Piper now produces an exciting range of stainless steel performance manifolds. These manifolds are made from high grade T304 stainless steel and will increase power and torque by approx 10%. The manifolds are finished in a polished stainless steel and can be fitted to either a standard system or a Piper performance full exhaust system. The car will be slightly more responsive and mid range power will be increased. Superb fit with quality second to none.
