This crossover pipe replaces the heavier factory piece with lighter weight 304 stainless. Instead of the hydro-formed oval piece with crimps and restrictions added for factory clearances, this is a full 3" pipe with no restrictions. We don't expect any power gains with this piece (the factory piece is mostly free-flowing aside from the crimped sections). The slightly better flow will help throttle and turbo response, especially with downpipes. This crossover can be used with stock or aftermarket downpipes.
- Better throttle response and faster turbo spool up times
- Mandrel Bent 3" piping. Smooth transition to the exhaust system
- 100% Stainless Steel Construction
- Precision CNC machined turbocharger V-Band and flange
- Multiple finish options: brushed, polished, black thermal ceramic
