ESS 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 aggressive exhaust note while retaining the rest of the stock exhaust system.

To take full advantage of this product and do not have increased emissions errors we recommend our in-house developed M3 performance software.

ESS 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.
