These studs will save the day! Stripped or corroded exhaust manifold studs are a major pain to deal with. Rusted studs fuse themselves to the nuts and back out of the cylinder head. These are M6x35 stainless exhaust manifold studs with new copper nuts that will make your manifold install a breeze! These studs have an internal 3mm hex so no more "double-nutting" or stud installers are needed, so no more galling threads! These have been a best seller for us since the late 1990s!

Why own the only V8-powered M3 if you can’t actually hear it? BMW's E9X M3 features a hefty rear muffler assembly that silences the S65's distinctive soundtrack. While full cat-back systems can require a serious financial commitment, our new Muffler Delete Kit offers an affordable, no-compromise solution that brings your M3 to life!

This system transforms the character of your S65 by replacing the restrictive factory mufflers with a free-flowing, TIG-welded stainless steel assembly designed to amplify tone, shed weight, and preserve OEM fit and finish. Our design features dual 2.5" primary tubing that flows into adjustable 3" quad tips, creating a clean yet aggressive aesthetic. Up front, factory-style V-band flanges connect directly to the OEM midpipe—meaning no cutting of factory exhaust piping. At the rear, Accuseal slip-fit connections allow perfect tip alignment within the factory diffuser, ensuring a tailored, symmetrical look every time.

FEATURES

TIG-welded dual 2.5" primary tubing transitioning into adjustable 3" quad tips for a bold, refined appearance

OE-style V-band flanges for true factory-like integration—no cutting required

Accuseal slip-fit joints for full adjustability and precise tip placement

Utilizes factory hangers for a clean, bolt-on installation with zero drilling or modification

PRODUCT DEVELOPMENT

Our Rear Muffler Delete Kit is the result of advanced engineering, testing, and quality assurance by Turner’s Research & Development team. Every stage of development employs FARO laser scanning, SolidWorks 3D CAD modeling, and in-house rapid prototyping for precise fitment and design validation. Performance and durability are proven through Mustang AWD 500 SE dyno testing and Superflow SF-750 Flowbench analysis, ensuring each component meets Turner’s uncompromising standards for performance and quality.

Our new E36 Axle Back Exhaust is a versatile exhaust offering a number of options for E36 owners. With the factory exhaust you can upgrade to having valve control for different tone and volume options on the fly. For the fully upgraded or turbo owners this exhaust features a 2.0" to 3.0" exhaust pipe conversion and full 3.0" valved muffler that can be used with a custom full 3.0" exhaust.

When it comes to shopping for exhausts you want to find one that suits your driving style and sound preference. While one part of you wants to have a loud and aggressive sounding exhaust, there is another part of you that knows you don't want to wake up the neighborhood or annoy your significant other. Finally the answer to your dilemma, thanks to our engineers at Turner you no longer need to choose between rowdy and tame. With your new light-weight performance exhaust you have the option to go from tame and tasteful to loud and rowdy.

Our Valved exhaust was designed specifically for your E36 and there are no other options on the market like this. Control the tone and volume of your exhaust with the click of a button. With the valves closed you have a nice low tone and hearty exhaust note. When the valves are open you get complete unrestricted access to sound and power for when your at the track or just in the mood to let it rip.

Our Turner axleback features dual 2.0" to 3.0" adapter that connects directly to your factory mid-pipes. From the adapter is full 3.0" exhaust piping with a smooth flow path to lower back pressure which leads to increased performance and a smoother exhaust tone. The 3.0" rear exhaust section flows into a full 3" valved muffler. The muffler features integrated 3" exhaust tips for an aggressive look that fills out your rear diffuser to get the perfect appearance.

New in 2023 you have two new options for E36 exhausts, our Turner valved and non valved axle back exhaust setups. With our Non Valved Axle-Back you achieve a happy medium of volume and tone but without the ability to adjust the volume. Our Valved Axle-Back is another variation and a true weapon, not only does it have the option to fit to your factory exhaust system but it is also the clear option for those looking to make a full 3.0" exhaust. After putting together the front 3.0" exhaust section you can assemble it with our Turner Valved Axle-Back for not only a full custom 3.0" exhaust but also have the luxury of volume control all with perfectly paired integrated 90's styled exhaust tips that fill out the rear valance with perfect proportions.

Non-M Fitment:
Although we designed this exhaust specifically for the M3 model we felt it was a shame to rob this exhaust opportunity from the Non-M E36 owners. Face it, every straight six deserves a sweet exhaust. If you or your fellow enthusiasts feel so inclined our exhaust can be fitted to all standard 6 cylinder E36s. ** For non-m E36s you will have to slightly bend the exhaust hangers to get perfect fitment in the non-m rear bumper/diffuser. **

Dual 2.0" to 3.0" exhaust adapter

Experience a more engaging driving experience accompanied by weight savings, increased flow, and most importantly an exhilarating exhaust note!

The G87 is no stranger to performance. Right out of the box the new M2 features rocket-like acceleration, and great handling and is even offered with a manual gearbox. With the Turner Performance exhaust, you get a more engaged feeling improving the driving experience. Increased sound you can both hear and feel offers a direct line of feedback between you and the car. The added volume allows you to feel where you are in the power band without looking at your rpm gauge allowing you to feather the exhaust around turns and when shifting in your manual transmission. Along with the increased volume and feeling our exhaust features smooth transitions and improved flow for improved throttle response and sound on deceleration.

Our mission was to amplify the G87 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow, reduced weight by 18 lbs, and delivered an exhaust system that captures the full unrestricted sound of the twin-turbo inline-6 S58 engine. The increase in flow was gained from dual 3.0" 304 stainless steel exhaust pipes that feed into a free-flowing valved muffler. Our team designed this catback with flow in mind to ensure the exhaust would never be restricted. Weight reduction is achieved by replacing the factory piping with lightweight 304ss for a modest weight advantage free from the added weight of the bulky factory muffler. Paired with our exhaust is a valved muffler that allows for both a smooth tone and rowdy exhaust note that can be controlled with factory options. All of this plus the direct fitment and straightforward installation leads to our Turner Performance Catback exhaust being the clear answer in your mission to find the best exhaust for your S58-powered M2.

Part Design and Features:

Turner In-house designed and engineered using FARO ARM laser scanning technology and SolidWorks 3D CAD modeling for precision fitment.
T304 Stainless Material in a natural finish - 1.25mm wall thickness, back purged and TIG-welded throughout

Performance Catback Exhaust for pure unrestricted power and sound. This exhaust takes out all of the stop gates and pairs with the N55 for an iconic driving experience.

Take your N55 to the next level and show the S55 drivers who is boss with our Turner Race-Inspired Catback. This light weight and free flowing exhaust boasts a smooth, clean, and rowdy exhaust note. Although the N55 found in the F chassis of BMW features a loud "cold start" once the car is warmed up the exhaust lacks character and volume. The twin scroll turbo featured on your M2 does a great job of limiting the volume on the factory exhaust but we want to hear the exhaust! No more boring and subtle exhaust, in comes our Turner catback to drop weight, get rid of restrictions and release the full engine and turbo sounds!

When you are shopping for an F87 M2 you have two options to choose from. Your choice can be the standard M2 with the N55 engine or the M2 Competition that comes equipped with the S55. The best part about either the competition or non-comp M2 is you are still getting the "M" suspension, characteristics and drive. From our experience there is not a big trade off between the two models that can justify the price difference. With the N55 you get a lighter weight and extremely capable weapon. Paired with an intake, tune, and the our lightweight exhaust the M2 is not a car to be messed with.

We set out to amplify the N55 M2 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow, reduced your exhaust weight to a total of 28lbs, and delivered an exhaust system that captures the full unrestricted sound of the sonorous twin scroll turbo inline-6 N55 engine. The increase in flow is gained from true 3.0" 304 stainless steel front section that feeds into the straight-through free flowing rear section. We specifically designed this catback with flow in mind to ensure the exhaust would never be a restriction. Weight reduction is achieved by replacing the factory mufflers and resonators with straight through lightweight stainless for the most weight advantage possible. The best part of the race inspired catback is the capability to perform far beyond the point that the factory exhaust.

Here at Turner our mission was to amplify the G80/G82 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow and delivered an exhaust system that captures the full unrestricted sound of the sonorous twin turbo inline-6 S58 engine. The increase in flow was gained from smooth flow path dual 3.0" stainless exhaust pipes that feed into one of the best designed mufflers on the market. Our engineers specifically designed the muffler with flow in mind to ensure that even with the exhaust valves closed, our muffler flows better and sounds better than the stock muffler. The best part of our Turner performance catback is the capability to control just how aggressive you want to your exhaust to sound, far beyond the point that the factory exhaust is able to perform. All of this plus the direct fitment and straight forward installation leads to our valved exhaust being the clear answer in your mission to find the best exhaust for your S58 powered G80 or G82.

The G80 took the world by storm by breaking the mold of BMW's standard design language. With the G80 and G82, a whole new generation of M car owners emerged. At first people were hesitant about the larger more distinguished front grilles, but after the shock was gone the true glory of BMW's newest M cars began to shine. The G80 M3 and G82 M4 are incredibly capable cars out of the box and Turner's large range of upgrades means the sky is the limit. Give your G80 or G82 the aggressive exhaust note that you wanted from the factory with Turner Motorsport's G80 G82 Stainless Valved Catback Exhaust.

Let’s be honest—what’s the point of owning a B58-powered BMW if you can’t hear it? The factory M340i and M440i rear muffler assembly is oversized, heavy, and overly restrictive, muting the deep, aggressive tone the B58 engine was designed to produce. Our Muffler Delete System is the perfect solution for enthusiasts looking to unleash that signature turbocharged inline-six sound without the cost of a full cat-back system.

Engineered and manufactured in-house, this system replaces the factory rear muffler with a free-flowing, TIG-welded 304 stainless steel setup designed to enhance tone, reduce weight, and maintain OE-level fitment and quality. At the front, 3" primary tubing mates seamlessly to your factory midpipe using a durable stainless steel sleeve clamp. At the rear axle, the primary tubing transitions to dual 2.5" adjustable tailpipe sections for a clean, yet aggressive look. These tailpipe sections merge to quad outlets, designed for compatibility with our selection of 3.5" exhaust tips, allowing you to tailor the system's appearance to your liking. Accuseal-style, slip-fit joints allow for easy adjustment, ensuring perfect tip placement inside the factory rear diffuser. The result? A more engaging exhaust note and a clean, motorsport-inspired appearance that transforms your BMW’s personality both visually and acoustically.

Features & Benefits

TIG-welded 3" primary tubing transitions to dual 2.5" adjustable tip sections for a bold, refined look Accuseal slip-fit joints offer full adjustability for precise alignment and perfect tip placement Direct-fit design connects to the factory exhaust at OE cut points using the original sleeve clamps Quad 2.5" tip outlets compatible with Turner tip options in Brushed Aluminum, Black Chrome, or Mirror Chrome Utilizes factory exhaust hangers for a clean, bolt-on installation—no cutting or drilling required Kit Contents:

Mid-Pipes (Left & Right) Crossover Pipes (Left & Right) Tail-Pipes (Left & Right) Logo Bracket & Hardware (2) Accuseal-Style Exhaust Clamps (2) Sleeve Exhaust Clamps (4) Turner Motorsport 3.5" Tips – Choose Your Finish! Product Development
