Supersprint Metallic Cat System BMW E92 355i Coupe 07+
High horse power performance applications require the durability and free flow characteristics of metallic racing catalytic converters. Turning up the power or using you car on the track will quickly melt down and damage your O.E. ceramic catalytic converter. Each racing converter is manufactured to racing specifications utilizing a high heat resistant metallic core. The reduced cell count from the O.E. 400 C.P.S.I. to a high flow 200 C.P.S.I. makes the Supersprint racing converters the most free flowing on the market today. All components are 100% stainless steel, and all tubing is mandrel bent to assure you the highest flow volume. Legal only for racing vehicles which may never be used upon a highway. Not applicable or intended for street or highway use.
Supersprint products are developed around scientific knowledge. Supersprint designs and builds based on each engines performance characteristics. Because it is actually easier to lose horsepower through misuse of larger diameter tubing and badly designed silencers, exhaust flow rates and velocity are dramatically increased by Supersprint designs while still retaining factory OEM diameter tubes. All design is validated by extensive testing which includes hours of dyno testing on Supersprints exclusive in-house Maha 4-wheel chassis dynamometer. This rear muffler is constructed of 100% stainless steel. All internal tubing, resonators and tail pipes are stainless steel. Packing material is long-strand stainless steel wool and rockwool. These materials are manufactured to Supesprint specs and provide much higher heat resistance than fiberglass. These materials insure a longer lasting system that will not blow out packing due to heat break-down, and tone that retains sound quality for many years.*Contact Us for special pricing.*
