Complete transformation for your 1 series. Direct bolt on muffler delete for a rowdy sound and a new and improved aggressive diffuser to compliment the exhaust.

A full aesthetic and sound transformation that is a direct fit solution. Both the diffuser and muffler delete are a direct replacement for the factory unit that can be upgraded with hand tools, no cutting or modification necessary!

M-Sport Rear Diffuser Upgrade:

Presenting the ECS rear diffuser tailored exclusively for your 1 Series – a fusion of both aftermarket and factory styling. Rarely does one find a design that not only encapsulates every curve and contour of a vehicle but elevates its overall aesthetic with a single, impactful addition. Amongst the limited options available for the 1 Series, the engineers at ECS have risen to the challenge of providing aftermarket support for these perfectly sized vehicles.

The diffuser replaces the mundane factory M Sport diffuser with a perfectly fitting alternative, designed to enhance the rear end of the 1 Series. Using the existing factory hardware and tab mounting locations, a transformation is merely a few screws and a plastic trim tool away. During the prototype phase, an impressive fit and finish were achieved, but their commitment to excellence led them to make further refinements. With the updated design, the ECS diffuser is now polished to perfection, an indication of the craftsmanship invested in each product.

Installation is a breeze, requiring no drilling, cutting, or modifications of any kind. Simply remove the current valance, align the tabs, and effortlessly secure the diffuser in place using the factory mounting locations and hardware. Ensure a snug fit by verifying the alignment of all tabs, and with a gentle press, witness the tabs seamlessly click into position.

For those with a 1 Series, anticipate a wave of excitement as a range of exhaust options tailored to all motor variants, including the N52, N54, and N55, are unveiled.

Features and advantages:

Transformative
Enhances the rear aesthetic of the 1 Series

Crafted from lightweight, vacuum-formed UV-stabilized gloss black ABS polymer
Compatible with both E82 and E88 models equipped with the M-Sport Package

The ECS muffler delete removes the heavy and restrictive factory exhaust muffler and replaces it with a high-flow, straight-through exhaust pipe. This adds a louder exhaust note in a simple, cost-effective way without replacing the entire exhaust system and is fully compatible with the OEM rear valance. The muffler delete creates a noticeable increase in exhaust sound and more exhilarating turbo noise, without adding significant drone at cruising speeds. As an added bonus, this muffler delete shaves off 23.0 lbs., weighing in at only 7.0 lbs compared to the OEM muffler at 30 lbs!

Refresh and upgrade your front intercooler to ensure you are supplying your engine with the maximum amount of airflow. With the added charge pipe and BOV kit you can drive confidently knowing the plastic charge pipe is replaced with a much stronger metal alternative with added blow off valve for a full performance and sound upgrade!

OEM+ Upgraded Front Mount Intercooler:

Upgrade your N54/N55 performance effortlessly with this "OEM+" Intercooler from ECS Tuning! This premium intercooler is engineered to deliver superior cooling efficiency and increased horsepower without the hassle of extensive bumper/core support modifications.

Key Features:

Enhanced Core Depth: Featuring a robust aluminum bar and plate core, this intercooler ensures optimal heat dissipation for peak performance.

Perfect Fitment: Designed to fit just like the OEM unit, it requires no additional brackets or modifications to the bumper or core support.
Compatibility: Works seamlessly with OE charge pipes and pipe connectors for easy installation.
Benefits:

Improved Cooling Efficiency: Significantly lowers intercooler outlet temperatures, ensuring your engine runs cooler and more efficiently.
Increased Durability: Aluminum end tanks offer enhanced durability and longevity compared to factory plastic construction.

Whether you're after increased performance or an OEM purist, the ECS Tuning OEM+ Intercooler is the perfect upgrade for your BMW. Enjoy the benefits of increased horsepower and lower temperatures with an easy, hassle-free installation.

N54 Chargepipe and BOV Kit:

All of the tuning in the world is only as good as the weakest link. More boost in your 135/335 is great! But you will soon learn that some of the factory hardware is not up to the task of handling that extra pressure. One of the first things to fail and cause a boost leak are the factory boost diverter valves. This allows boost to "leak" out of the intake stream and a loss of power from the engine. This ECS Tuning chargepipe upgrade includes a blow-off valve in place of the factory diverter valves. The BOV is higher quality than the diverter valves and will exit intake air to the outside instead of putting it back through the turbo system (which will reduce strain on the turbos). This aluminum chargepipe is also much more robust than the stock plastic factory pipe and the connection to the throttle body is stronger, eliminating another failure point of the stock pipe.

Built-in 1/8" NPT ports allow you to run an additional methanol injection kit (bungs included if you don't want use the ports).

This is a complete kit that includes everything you need to replace the factory chargepipe and diverter valves -

powedercoat chargepipe
ECS Tuning blow-off valve
multiple BOV springs to suit your vacuum/boost needs
vacuum plugs for the stock diverter valve hoses
silicone hose connection to intercooler piping
all hardware and hose clamps with instructions

N55 Performance Cat-Back Exhaust - E82/E88 135:

Lightweight cat-back featuring an exotic exhaust note. Designed for the perfect blend of performance and functionality!

Prepare to give your 1 series the boost it deserves. This cat-back exhaust was made to redefine the driving experience of your 135. Manufactured from premium brushed stainless steel, it is not just about reducing weight; it's about enhancing performance with unrestricted airflow. And the sound? It's a symphony of power and precision, carefully crafted for an unforgettable soundtrack. The sound experience is more than you could ask for. With the freedom of exhaust- flow and tuned exhaust note, we are very excited to get these exhausts on 135's everywhere, don't wait!

Featured on the ECS Tuning YouTube Channel! - CLICK HERE FOR SOUND CLIPS! -

When crafting the ECS exhaust systems, their primary focus is on achieving the perfect balance of sound and comfort. ECS's understand the desire for a thrilling exhaust note without the annoyance of highway drone or interior vibrations. The exhaust for your 135 incorporates this balance, offering a strageic blend of sportiness and practicality. Drawing from their extensive experience, particularly with N55 cars like the E9x series, they have engineered an exhaust packed with innovative features, compatible with both factory and aftermarket downpipes. Experience the perfect blend of performance and everyday usability.

There is something about a cat-back exhaust that is just so good. Being able to unbolt and replace the entire visible exhaust gives you butterflies in your stomach. A fresh new exhaust and just knowing that things are about to get rowdy. This exhaust features twin 2.5" brushed pipes with flanges that bolt directly to your factory and aftermarket down-pipes. The dual 2.5" mid-pipes make their way toward the rear axle and converge into a single 3" exhaust section. The 3" exhaust section snakes through the rear section of the car making smooth dips and curves to make its way into a light-weight 3" turbo style muffler. Don't be fooled by the 135 muffler, the size is nothing but deceiving. The turbo-style muffler features an inner design that refines the exhaust note to perfection. An extraordinary mixture of both tone and volume. Paired with the 3" muffler is your choice of 3.5" exhaust tips that give your rear diffuser a sporty look that shouts performance.

Although both N54 and N55 share identical exhaust geometry, the N55 mid-pipes do not feature secondaries. Though the N55 cat-back is compatible with N54 downpipes this is not suggested. Supposedly this N55 catback sounds absolutely glorious on an N54, even with aftermarket downpipes.

Upgrade your E9X BMW with this all-in-one Turner Motorsport bundle featuring Fixed Camber Plates and Monoball Front Thrust Arms. Designed to improve handling, reduce deflection, and increase steering precision, this package delivers a noticeable performance boost both on the street and track—all without breaking the bank.

E9X Front Camber Plates – Fixed Position

Most BMWs leave the factory with conservative front camber to encourage understeer, which compromises handling and accelerates tire wear by reducing contact patch engagement. Turner Motorsport’s Fixed Camber Plates are a simple, effective solution, adding up to 2.5° of negative camber to your E90, E92, or E93.

By increasing front negative camber, you’ll enjoy:

Improved turn-in and cornering confidence

Reduced tire wear

Better overall handling balance

Designed with expertise gained from Turner Motorsport’s participation in the Speed World Challenge series, these plates are offset for the optimal camber/caster combination when running stock-diameter springs. They add only ~6mm of ride height and utilize the factory upper strut mount for a clean, straightforward installation—perfect for racing classes where adjustable camber plates are restricted, or for enthusiasts who want a simple, cost-effective negative camber upgrade.

Installation: Press out OEM studs and alignment pin; see Turner’s detailed PDF for guidance.

Monoball Front Thrust Arm Upgrade Kit

BMW’s stock front thrust arm bushings are soft, compliant, and prone to wear—allowing fore/aft wheel movement that degrades steering feel, alignment, braking response, and tire performance. While designed for comfort, these OEM components fall short for enthusiasts and track-focused drivers seeking maximum control.

Turner Motorsport’s Monoball Front Thrust Arms solve these issues with:

Sealed OEM BMW ball joints for exceptional durability

CNC-machined 6061-T6 anodized aluminum bearing assembly with knurled OD for perfect press-fit and long life

Low-friction, no-bind design to eliminate unwanted suspension deflection

The result? Instantaneous turn-in, precise steering, direct braking feedback, and exceptional suspension feel, all while maintaining comfort and reliability for daily driving. Perfect for track use or spirited street driving, these thrust arms are a no-compromise upgrade for anyone looking to enhance BMW front-end performance.

N55 Charge Pipe Kit:

If you are looking to improve your intake system, a major component to consider is your charge pipe and boost pipe. The stock plastic BMW charge pipe is flimsy, prone to cracking, and restricts airflow at high RPMs. This results in unreliability and restricted power. ECS Tuning's new line of powder-coated Aluminum Charge Pipes are designed to replace your stock pipes, offering increased strength, reliability, and higher airflow!

Using aluminum construction and black powder coating, this pipe not only looks great but is structurally stronger and won't crack after long-term exposure to heating/cooling cycles. This is perfect for anyone who is looking for more power, whether the car is stock, or highly modified.

Additionally, all OE ports are retained and all clips and seals are included for installation! There's no longer a need to reuse your stock clip and o-ring.

As an added bonus, a water/meth bung has been added to the design for those who are looking to get the highest levels of performance out of their BMW's engine!

Features:

OEM Fitment
Increased diameter and airflow
Increase throttle response and decreases turbo lag.
Powder-coated black aluminum piping.
CNC Machined Throttle Body Flange
Includes one 1/8' NPT bung for meth/water injection.
Includes everything necessary to upgrade from factory chargepipe.
4-Ply Reinforced Silicone Coupler
1-Year Limited Warranty against defects or workmanship

Doorbuster Bundle! Turner Motorsport Polyurethane Shifter Arm Bushing with Every DSSR Purchase for E8X/E9X RWD Models!

Upgrade your shifting setup and feel the difference! This limited-time kit includes a FREE Polyurethane Shifter Arm Bushing when you buy the Turner Motorsport Dual Shear Selector Rod (DSSR) for your E8X or E9X 135i/335i. Make gear changes tighter, crisper, and more precise with this unbeatable pairing!

Turner Motorsport Dual Shear Selector Rod (DSSR)

Enhance your N54-equipped 135i or 335i’s driving feel with the Turner Motorsport DSSR. Designed to give your shifter a much more precise and solid connection, this DSSR replaces the OEM selector rod, eliminating the play and deflection that come from single-shear designs. Pair it with a Turner short-shift kit for the ultimate shifting upgrade.

Think of the DSSR as a major upgrade from the single-contact OEM rod, much like riding a bike with two hands instead of one: you have stronger, more precise control over each gear change. With its dual-contact setup, the DSSR “sandwiches” both sides of the shifter and transmission, creating a direct link that feels solid, eliminating the vague and sloppy feel of the factory setup.

Key Benefits:

Enhanced Precision: Significantly reduces deflection and play, giving you a more connected feel while shifting Compatible with Factory & Aftermarket Shifters: Perfect for custom setups as well as stock configurations Durable Build: Fabricated from high-quality 303 stainless steel, offering rust resistance and longevity Complete Hardware Included: Comes with zinc-plated hardware for a secure installation Specifications:

Material: 303 stainless steel construction Compatibility: Replacement for part #25117524722 (E8X/E9X N54 models) Installation Design: Two-piece assembly with captive pins, designed for simple alignment and adjustability Fitment: Specially engineered to fit the tight N54 carrier without interference Installation Tips:

Remove your factory selector rod and take note of its orientation. Attach the DSSR to both the transmission selector joint and lower shift lever. Shift to 3rd or 5th gear for maximum access to the supplied hardware, then secure tightly. Turner Motorsport Polyurethane Shifter Arm Bushing

Want more responsive and accurate shifts without sacrificing comfort? The Turner Motorsport Polyurethane Shifter Arm Bushing is the perfect enhancement to reduce unwanted movement and play in the shift arm assembly. Factory rubber bushings absorb vibrations for smoothness but compromise direct feedback and often wear out, leading to sloppy, imprecise shifting.

Crafted from high-performance polyurethane with a corrosion-resistant 304 stainless steel sleeve, this bushing maintains stability without stretching or wearing out like rubber. Experience the tactile feel of more precise shifts, with minimal NVH (Noise, Vibration, and Harshness) added to your drive. A must-have for any driver looking to take control of their BMW's performance.

Key Features:

Precision Control: Firmer than factory rubber for a crisp, responsive shifter feel Long-Lasting Materials: Made with durable 70a polyurethane and a 304 stainless steel mounting sleeve Easy Installation: Direct replacement—no modifications needed OEM Compatibility: Replaces BMW part numbers 25111222015 and 25111222652 Specifications:

Material: High-quality 70a polyurethane and 304 stainless steel Made in the USA: Proudly manufactured with quality materials Durability: Improved lifespan over factory rubber bushings, reducing slop and enhancing gear engagement Don’t miss out on this Doorbuster Deal!
