The Blitz Front Pipe connects the exhaust diffuser (dump pipe) through to the catalytic converter. The front pipe must be as free from bends as possible and have adequate diameter to ensure turbulence-free exhaust flow. The Blitz Front Pipe has been designed with these considerations in mind with diameters between 2.5" and 3".
