Tegiwa Primary Decat Pipes (E9X M3)
Tegiwa Primary Decat Pipes, or ‘Test Pipes’, for the E90/E92/E93 M3.
These are the perfect way to de-restrict the exhaust system of the S65 engine, with gains of up to 40bhp in conjunction with a remap (required). Requires cutting of the original exhaust – these stainless steel pipes then have a slip fit over the existing pipes, replacing the primary catalytic converters. Provides improved sound, throttle response and performance.
Priced per pair.
