BMW E28 Supersprint Exhaust Systems 

Description: Supersprint Inc. was formed in 1955 with the objective of designing and building the highest quality exhaust systems in the world. That objective has been the driving force behind each Supersprint product from the first system built to those being developed for the future. When you purchase a Supersprint product you can be assured it is the highest quality available. All design is validated by extensive testing which includes hours of dyno testing on Supersprint's exclusive in-house Maha 4-wheel chassis dynamometer. When compared to a domestic stainless system, the Supersprint Stainless system showed a 30% flow improvement over the Factory M3 system. To protect against corrosion each non-stainless system receives an aluminized coating inside and out. All internal tubing, resonators and tail pipes are stainless steel. Packing material is longstrand stainless steel wool and rockwool. TÜV Approved.
