BMW Exhaust Parts, Mufflers & Catalytic Converters

Our Race Inspired exhaust deletes the rear mufflers in the F10 M5 to allow more of the exhaust sound to be heard. We love our M5 but it's just too quiet so we looked at ways to get more of the stock exhaust to be heard. After evaluating the stock exhaust layout it was easy to see that removing the rear mufflers would accomplish what we wanted. But cutting the mufflers off is just the beginning. We then had to develop a set of pipes and design a set of tips that fit perfectly and also looked right at home on the M5 super sedan. And these M5 muffler delete pipes are the finished product.

Our axle-back exhaust is made from a 304 stainless steel tube in the same diameter as the stock exhaust and with mandrel bends for unimpeded flow. It fits with the stock hangers and is clamped to the stock exhaust pipes once the mufflers are cut off. And the entire installation can be done in about an hour with the exhaust on the car. With factory clamps, you can easily reinstall your stock mufflers or a set of Corsa Performance mufflers at any time. Our tips are also stainless in a perfectly proportioned 89mm (3.5" diameter). They fill out the rear bumper valence perfectly - not too small like stock and not boy-racer large. Tips are available in mirror silver or brushed aluminum..

The final result is that removing the stock mufflers really lets the M5 V8 sing! With the mufflers and flapper valves removed the sound on start-up is scintillating. The sound from the S63TU engine is robust and intoxicating - it just needs to be heard! From outside, the muffler-delete exhaust makes the car seem all the more impressive. From the burble at idle to the roar under full throttle there is little doubt that this is a proper M car. Inside the car during normal driving the sound is not changed much thanks to the Active Sound Design system. It's a little louder but not intrusive or irritating. Around town the car sounds much like stock but just a touch louder. The exhaust pops and burbles more with each downshift. On the highway at 70-80 cruising speeds it's as quiet as a muffled exhaust. We tried to get the exhaust to drone but only experienced it at low speeds in a high gear (i.e. - lugging the engine) which we normally wouldn't do.

Our Race Inspired M5 exhaust is perfect for enhancing and accentuating the stock sound. It lets more of the M5's soundtrack come through without extensive exhaust modifications. If you want to enjoy the M5's sound more, think of this as its volume knob turned up.

The factory cast-iron exhaust manifolds originally fitted to M50, M50TU, and S50B30US-powered E36s are notorious performance bottlenecks, plagued by excessive weight and a tendency to crack over time. Our Equal Length "Shorty" Exhaust Headers offer the ultimate remedy. Engineered specifically to maximize exhaust flow and encourage exhaust gas scavenging, these headers unleash a noticeable boost in overall engine efficiency and grant your M5X that crisp, aggressive inline-six growl without sacrificing low-end torque.

Unlike restrictive, uneven OEM cast-iron manifolds, our design utilizes high-quality T304 stainless steel construction shaped by precision mandrel bending. This specialized process ensures a uniform pipe diameter throughout every bend to maximize exhaust gas velocity and eliminate internal turbulence. The flow-optimized, equal-length primary runners merge seamlessly into a heavy-duty cast stainless steel collector, creating a restriction-free transition that dramatically improves scavenging. Our refined design completely transforms your driving experience, delivering a deeper, more pronounced tone under load while remaining perfectly civilized and drone-free at cruising speeds.

Built to endure years of high-RPM track abuse and extreme thermal stress, these headers are engineered with longevity in mind. Every joint is meticulously TIG-welded for exceptional structural integrity, ensuring the tubes can handle intense heat cycling without cracking. To guarantee a permanent, leak-free seal, the headers feature thick, precision laser-cut flanges that aggressively resist warping over time. Best of all, this is a true, headache-free upgrade; they drop directly into the E36 chassis and mate perfectly with your factory mid-pipe using OEM gaskets and hardware, requiring absolutely no custom fabrication or modification.
