This dual out American Thunder cat-back exhaust system is the perfect choice with a 2.50-inch flanged pipe connecting directly to the catalytic converter and quickly transitioning to a full 3.00-inch mandrel-bent aluminized steel inlet tube flowing into a large case 80 Series Cross-flow performance muffler for a deep powerful sound.
