The Z06 exhaust is 3" from the factory, yet it necks down to 2.5" as it enters the mufflers, reducing exhaust flow and performance. The Billy Boat Bullet System is an entirely 3 inch, T-304 stainless steel system, using precision mandrel bends for uninterrupted flow and performance. The system uses a rear similar to a 3" version of the B&B Bullet system, using an additional small resonated muffler at the back of the system.
The muffler tips are double walled, 4" round or 4.5" oval. Theentire system comes completely polished and the result is a truly spectacular look and sound that gives this high performance sports car the look and aggressive sound which will have heads turning everywhere you go.
All B&B products are precision built in rugged fixtures, completely TIG welded, and are a direct replacement for stock exhaust components and include all hardware and gaskets. No machining, no cutting and no welding means easy installation. BB Part Number FCOR-0235.
