Description
When deciding on the right exhaust the hardest part is feeling confident in the best sound mixed with increased performance, this really leaves you to guess based on reputation. Fortunately, Supersprint has the reputation covered when it comes to BMW exhausts. For over 60 years their goal has always been designing and building the highest quality exhaust available. This has been achieved through extensive testing using real race teams to get the best feedback there is to offer, from the ones who demand the best everyday. Extensive dyno testing, high quality materials, and race team feedback are what allow Supersprint to extract the power from your engine, not just the noise.
This Supersprint performance exhaust is built from the Euro M5/M6 exhaust layout but fits the non-M E24/E28 (see fitment notes below). It features oversized dual 50mm stainless steel pipes leading from the catalytic converter. This Supersprint system has a center resonator and rear muffler with free-flow designs for a sporty sound and less restriction to free up horsepower. Both systems are bolt-on to the stock factory catalytic converter (see fitment notes below) and use all of the stock hangers and gaskets. This makes for an excellent replacement exhaust system because the sound is such a great match to the M30 engine and retro cool that these cars have now. It's a classic growl and throaty sound without being overly aggressive. We've had nothing but compliments on the sound from this system. The previous mild steel versions have been discontinued - this system is now 100% T304 stainless steel!
1982-1988 635, 1984-1988 535 models should have a stock 3-bolt flange where the center resonator and front catalytic converter meet. This Supersprint system is a direct bolt-on replacement to this system.
1988-1989 635 BMW changed the center resonator and cat flanges from a 3-bolt triangle to a 2-bolt diamond-shaped flange. The Supersprint center resonator uses the 3-bolt flange. So you must either cut off the 3-bolt flange and reinstall the original 2-bolt flange. Or cut the 2-bolt flange from the cat and weld on a new 3-bolt flange (BMW p/n 18111178137 and gaskets p/n 18301723886, available separately).
This system was originally designed for the Euro E24/E28 which does not have the rear hanger attachment over the tips like on a US model (you will need the Euro hanger setup). In addition the tips are shorter on the Euro muffler since the Euro bumpers do not extend as far as the US bumpers. So the tips on this muffler will sit just past the valance but tucked far under the bumper.
