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!

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.

E36 Sedan LTW Spoiler:

Experience a modern interpretation of LTW styling with our latest creation. Inspired by the classic E36 lightweight, and crafted with precision by our expert engineering team at Turner, we proudly introduce our carbon LTW spoiler, setting a new standard in the industry. Carefully crafted with a multi-piece carbon design, our spoiler is not just an accessory; it's a work of art featuring a flawless glass-like finish and perfectly matched carbon weave.

As fellow enthusiasts, we understand the importance of preserving the integrity of E36s and their components. With iconic colors like Techno Violet, Boston Green, and Estoril Blue in mind, we refuse to compromise the original trunk and paint with traditional drilling methods. Instead, our carbon LTW spoiler features an innovative fastening system that requires no modifications and preserves your car's pristine showroom finish. With precision-engineered billet clamps and high-quality 3M double-sided tape, installation is a breeze, requiring only basic hand tools. No drilling is necessary.

Research and development:

We feel it is crucial to share our journey into the design and engineering that went into developing this remarkable carbon spoiler. The development of this LTW spoiler was not a quick process; it spanned over three years. Throughout this time, we dedicated ourselves to refining, testing, and making adjustments to craft a spoiler that we're thrilled to introduce to the community.

From perfecting the form and fitment to ensuring the spoilers's stability, every aspect of this project presented significant challenges. This carbon spoiler is comprised of 5 components, the base spoiler, 70mm risers, upper spoiler, gurney flap, and most importantly the mounting brackets.

Anyone familiar with carbon fiber knows the difficulty of working with these nearly 50-inch wide pieces to achieve straightness without flex while maintaining a consistent carbon weave pattern. During the initial stages of carbon testing, the manufacturing process proved to be nothing short of impossible. Issues such as carbon fiber twisting during curing, waviness in the exterior appearance, and mismatched carbon weave posed significant hurdles.

Furthermore, ensuring precise fitment was paramount. Not only did the spoiler components need to seamlessly integrate with the trunk gaps, but they also had to clear adjacent body portions without error. We underwent rigorous testing, cycling through five sets of carbon spoiler prototypes before achieving a result that met our exact standards.

Numerous adjustments were made throughout the project, including modifications to the carbon composition, bracketry, and the incorporation of gaskets between carbon layers. Our passion and dedication were poured into every aspect of this product.

Throughout the project timeline, we conducted extensive long-term testing on various vehicles, subjecting the spoiler to speeds beyond what can be publicly disclosed. When we say these spoilers are secure, we mean it. Utilizing both 3M double-sided tape and four billet brackets with a total of eight fasteners, this spoiler can be confidently installed. The billet mounting brackets are designed to fasten over the top of the factory seam sealer on the underside of the trunk for maximum stability. Near the end of testing, we decided to add an adhesive-backed gasket to the underside of the base, providing yet another layer of paint protection.

Styling:

The greatest part we have enjoyed over this project is the versatile style of the spoiler as designed. If you have read this far into our development process we can strongly say that you are a true car enthusiast. As car enthusiasts we can never leave the car alone, changing setups and most importantly styling. With the multi-piece design, the option to change up your look is just moments away with a little help from some hand tools.

Initially, we were fully committed to running the complete setup: full height, 70mm risers, and gurney flap – all inspired by the LTW look with a modern carbon twist. However, as we spent more time with the spoiler, our perspective shifted. We decided to remove the 70mm risers and suddenly rediscovered our love for the E36's original aesthetic. Without the risers, the spoiler took on a new, understated elegance, blending seamlessly with the car's overall design.

Time passed, and we began to explore other options. Removing the gurney flap toned down the race car vibe, revealing yet another layer of the spoiler's versatility. Each subtle alteration brought about a significant change in style, proving that even the smallest adjustments could make a world of difference.

Our journey with the spoiler was one of constant evolution; from full-on LTW racing aesthetics to more understated styling and back again. This flexibility was the true beauty of our creation, keeping us engaged and dedicated throughout the rigorous development process.

E36 M3 Street Flow Rear Diffuser

Add-on diffuser to deliver a true motorsport look to your M3. Fastened seamlessly to the bottom of the rear bumper giving a platform to show off your exhaust and complete the rear end of the E36.

The E36 M3 is an amazing looking car right out of the box but a common BMW issue is the height of the front vs rear bumpers. As far back as the E30, the front bumper is much lower than the rear bumper and the E36 M3 faces the same issue. With this problem the front bumper is always super low to the ground and the rear bumper looks in-complete. The ECS add-on diffuser is a unique option for balancing out the rear bumper with the height of the front bumper for a full and complete look.

Give your M3 that wild style that stands out from the crowd, and obtain a nice balanced look. This is just the start of a new line of Street Flow Diffusers diffusers that are a must have extension of your awesome ride. The diffusers come powder coated in a sleek satin-black finish, are a blast to install and fit seamlessly against the rear bumper for a professional looking install every time. The Street Flow diffuser attaches below your factory rear diffuser and exhaust of your choosing to fill out the rear end for a nice full and aggressive styling profile.

Lets take a trip together down a new and unique path. Over the years ECS has designed factory replacement ABS and Carbon Fiber diffusers for all different models of BMW's. For the factory replacements ECS focus was to take the oem characteristics and add a twist and really bring out a more aggressive look with a direct replacement diffuser. For their new line of diffusers, us as car enthusiasts wanted to design a set of diffusers that really pushed the envelope and stepped outside of our comfort zone. Our new line of add-on diffusers is a result of our engineering team and fellow enthusiasts spending time study the M3 chassis, modeling different designs, testing prototypes and making changes to get a final product that we are extremely excited to offer. The E36 M3 Street Flow Diffuser is the first in our line of new diffusers. Stay tuned for the E92 M3 diffusers next!

Features:

Adds an aggressive aesthetic in addition to the subtle factory rear diffuser
Lightweight and durable 10ga aluminum in satin black powder coat to blend with the factory trim color
Installation is secure and simple with ample adjustability built in for perfect fitment
Design:

10 ga 5052 aluminum construction

E36 Coupe LTW Spoiler:

Experience a modern interpretation of LTW styling with our latest creation. Inspired by the classic E36 lightweight, and crafted with precision by our expert engineering team at Turner, we proudly introduce our carbon LTW spoiler, setting a new standard in the industry. Carefully crafted with a multi-piece carbon design, our spoiler is not just an accessory; it's a work of art featuring a flawless glass-like finish and perfectly matched carbon weave.

As fellow enthusiasts, we understand the importance of preserving the integrity of E36s and their components. With iconic colors like Techno Violet, Boston Green, and Estoril Blue in mind, we refuse to compromise the original trunk and paint with traditional drilling methods. Instead, our carbon LTW spoiler features an innovative fastening system that requires no modifications and preserves your car's pristine showroom finish. With precision-engineered billet clamps and high-quality 3M double-sided tape, installation is a breeze, requiring only basic hand tools. No drilling is necessary.

This solution not only guarantees the carbon cosmetics will always play well with any personalization of the exhaust that is adopted but also offers an economical option compared to much pricier alternatives. Together with the Dinan Rear Side Splitters, the combination creates a "full" rear diffuser that is restrained but elevated and creates a nuanced OEM+ option for the marketplace. Features: 2x2 gloss twill dry carbon fiber (pre-preg) manufactured to be impact-resistant, durable, and strong Clear-coated for maximum UV protection and fade resistance Utilizes factory mounting tabs for an easy installation with a clean fit and finish Pair together with the Dinan Rear Side Splitters to complete the full rear look

Carbon fiber is a staple in the performance world and has been incorporated into motorsports since the early 80s. Over time companies have taken it upon themselves to create new carbon products to add to your car that may have not been originally available. Autotecknic is no different. If you're looking for a carbon addition that has been made to the highest standards with premium materials, then Autotecknic's line of carbon additions is your one-stop shop. Add some carbon to your M-Performance rear valance! Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold and then into a sealed autoclave to cure properly. This method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means fewer pinholes and virtually no air pockets in the carbon. Dry carbon is the highest-quality version of carbon fiber products that are produced.

Carbon fiber is a staple in the performance world and has been incorporated into motorsports since the early 80s. Over time companies have taken it upon themselves to create new carbon products to add to your car that may not have been originally available. Autotecknic is no different. If you're looking for a carbon addition that has been made to the highest standards with premium materials, then Autotecknic's line of carbon additions is your one-stop shop. Give your M5 a more aggressive appearance with this dry carbon fiber diffuser! This carbon fiber center diffuser comprises 100% pre-preg dry carbon technology for the ultimate lightweight, high-durability, and precise fitment. Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold and then into a sealed autoclave to cure properly. This method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means fewer pinholes and virtually no air pockets in the carbon. Dry carbon is the highest-quality version of carbon fiber products that are produced.
