This already assembled kit for your E90 is sure to make the most of the N52 engine note! This kit retains the stock secondary cats. Consists of Non-Resonated section 2 center pipes with Supersprint's Performance Muffler featuring 80mm diameter exhaust tips. Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preference. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Add a little more growl and sporty exuberance to the E32 740 with the Supersprint performance exhaust. This cat-back system has a tuned center resonator and sport muffler. Both are freer flowing than the stock 740 exhaust which gives a more sport-oriented sound and a modest power increase thanks to less restriction. Supersprint exhausts are often found on restored classic BMWs as a mild sport exhaust, thanks to their OEM quality and refined sound. The complete system is stainless steel and a direct fit to the stock catalytic converters (with the appropriate adapter pipe for the SWB or LWB).

This Supersprint performance exhaust is built from the Euro M5/M6 exhaust layout but fits the 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!

Fitment Notes: This rear muffler fits with the stock 535/635 US rear bumper.

  • 1982-1987 535/635 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. It has 3-bolt flanges.
  • 1988-1989 635 uses a 2-bolt flange on the stock cat section and that flange must be removed and replaced with the triangular 3-bolt flange (BMW p/n 18111178137) and gaskets (p/n 18301723886). Or remove the 3-bolt flanges from the Supersprint and re-weld the old 2-bolt flanges from the stock US resonator section.
  • 1985-1989 M5/M6 requires the complete Supersprint exhaust
