Use the "sport" button to divert routing to switch from flowing through the side mufflers to a direct "bypassed" flow.
The first thing you’ll notice will be the rich, mellow sound delivered by the chambered muffler. The second thing you’ll notice is the improved performance as lowered backpressure and improved scavenging let your engine deliver more power and torque. The third thing you’ll notice is more money in your pocket after you fill up. With all the tubing mandrel-bent without reducing its cross-section, and every bend made to the minimum bend angle, MBRP exhaust systems can substantially reduce backpressure through the system. You don’t need to expend horsepower forcing exhaust gases through a pinhole, and improved scavenging of those same gases means more mixture drawn into the cylinders for more power. It’s a win-win deal. MBRP engineers all of its systems to fit perfectly the first time. You’ll be able to install your MBRP exhaust system with nothing more than simple hand tools. MBRP’s Bypass Muffler Kit is constructed entirely of T304 stainless steel.
