Product Description

Your car's factory exhaust was designed by an accountant, not a racer. It uses narrow, crushed piping to keep the car quiet and cheap, effectively choking off your engine's potential. Upgrading to this Performance Exhaust System is like taking a gag off your motor. By widening the path to 3 inches and using smooth mandrel bends, we allow the engine to exhale freely. Less backpressure means the piston doesn't have to work as hard to push exhaust out, which translates directly into more torque and horsepower at the wheels.

But let's talk about the style. You aren't just buying performance; you're buying a presence.

• The Single Wall Option: With a massive 4.5" Tip, this is for the driver who wants to be seen. The Burnt Tip finish gives you that titanium-race-car look, while the Polished finish keeps it classic and clean.

• The OEM Style Option: Perfect for the driver who wants the performance gains and the deep sound, but wants to keep the visual profile a bit more subtle and refined.

Regardless of which tip you choose, you are getting T-304 Stainless Steel armor that will outlast the car itself. Don't settle for the tinny, restrictive noise of a stock system. Bolt this on, turn the key, and fall in love with the throttle response all over again.
