E9x M3 Test Pipes

Expected release date is May 31st 2018

Product Description

Our E9x M3 test pipes are designed to improve performance by removing the exhaust restriction caused by the factory primary catalytic converters. Replacing these cats with a straight pipe design allows the car to gain up to 15 HP and provides a more agressive exhaust note while retaining the rest of the stock exhaust system. To take full adavantage of this product and to not have increased emissions errors we recommend our specially developed M3 performance software. Our test pipes are compatible with all NA and supercharged vehicles. Installation is done by removing the front section of the stock exhaust system and attaching our test pipes in place with the supplied clamps. This system is designed for off road use only and will not pass emissions testing.
