E90/92/93 335 Sedan/Coupe Muffler w/ Single Round Tip (90mm)
The Supersprint rear mufflers are of the performance proven flow through resonated design, rather than the baffled chamber design used by the factory and many other manufactures. The internal tubing diameter optimizes performance while the long strand rock wool sound deadening material provides the mature tone that Supersprint is so well know for. Tubing diameter is increased from the factory 57mm to 60mm for additional backpressure reduction. The factory one-piece muffler system has a complex design, which includes a built in flapper valve on one side of the system that has the sole purpose to alter the sound note at certain pre-set rpm levels. This design reduces performance at low RPM. Supersprint rear mufflers alone increase the torque and max hp by a significant amount, especially at low rpm. The results are a mature aggressive sound free of droning, even at low rpm and high loads. The results of installing the complete Supersprint system are aphenomenal 26 hp with a torque gain over 20 lb/ft.
Mounts to stock exhaust or with Supersprint Crossover pipes; 100% stainless steel. These mufflers produce a throatier growl from the engine without any dramatic after effects. What you get is a strong burble at idle and low rpm and a sporty rip at higher rpm.
Note: The single tip 90mm round system is a direct bolt on requiring no rear valance modifications. Price includes both left and right mufflers.
