Test Pipes / Cat Delete - BMW E9X M3


Product Description

The Test Pipes features a expansion slot at the rear of the Test Pipe to provide that tight exhaust gas seal with the help of the European designed TORCA style clamps.

An additional support brace is also provided (just like the factory) to relieve the load and stress if installed. 
The gains in horsepower through the free flowing design of the Test Pipes and the replacing of the factory catalytic converters by removing the restrictions of the stock cats. With guaranteed HP gains this application is a must for the track user.
Removal of the catalytic converter involved. Check your local emissions requirements for licensed street cars.
