This performance resonator features a straight-through design to promote uninterrupted exhaust flow. With its 2.25" inlet and outlet ports and 12.6" overall length, it reduces engine noise while maintaining power. The dark tone muffler delivers a deeper tone without sacrificing flow. For durability, it undergoes a polishing treatment on its stainless steel surface to withstand high exhaust temperatures. Professional installation is recommended due to welding requirements. It comes with a 2-year warranty to protect your investment.
