Turner Motorsport BMW Exhaust Parts, Mufflers & Catalytic Converters

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.

The S54 under the hood of your E46 M3 is a high-revving masterpiece, but factory exhaust setups and many aftermarket options leave you stuck with that dreaded, tinny exhaust rasp. The Turner Motorsport Equal Length Section 1 Exhaust is built to cure the S54's sound once and for all, delivering the aggressive, track-inspired tone your M3 deserved from the factory.

We designed this equal-length section 1 pipe with a proprietary internal resonator that smooths out exhaust pulses, completely killing unwanted rasp while dialing in a throatier, exotic sound profile. Built from heavy-duty 304 stainless steel with precise pie-cut welds, it’s engineered to withstand the thermal stress of aggressive track days and daily street driving without rusting or deteriorating. It’s a 100% direct bolt-on upgrade using existing factory hangers, meaning you get pure motorsport sound and performance with an effortless installation.
