This intermediate stainless steel Sport exhaust tube replaces the stock intermediate exhaust muffler (reference 911.010478) or the catalytic converter, for vehicles that are so equipped. It optimizes the outflow of exhaust gases from the engine and reduces back pressure. This has the net effect of increasing available engine power.

 

This Sport by-pass tube is also fitted with a mounting nut for your Porsche’s oxygen (Lambda) probe.

 

This Sport by-pass tube is recommended for track use.            

 

Quantity required per vehicle: 1

 

Note: This Sport by-pass tube cannot be mounted on 911 Turbo’s. This item is sold separately.
