VRSF E9X M3 S65 Test Pipes

Unleash the sound of your S65 V8 while adding performance with a set of VRSF Test Pipes for your E9x M3! With not enough performance mods available for the E9X M3, we offer the catless test pipes. Removing restriction will automatically increase performance gains on any car. By removing the catalytic converter, you will have increase airflow through the exhaust. This will also increase sound and a little smell. By running catless you may find gains upwards of 25 hp and 25 tq.  By eliminating the restrictive 400 cell catalytic converters in the factory downpipes, back pressure is reduced significantly which results in an increase in power & a more aggressive exhaust note. These bypass pipes are constructed from mandrel bent, 304 grade stainless steel and are designed to work with the OEM exhaust. Welding is not required for installation, just cut and bolt into place using supplied exhaust clamps. Professional installation recommended. Made for E90,E92,E93 M3. Tune required to eliminate the CEL that may appear.   Made for off road use only.
