I bought this for my 2007 Jeep Wrangler after I had the engine charged. The previous muffler, The one I used had too much back pressure and kept blowing through the exhaust pipe and cracking the exhaust manifold on the driver's side due to the 2.0" inner baffles. This muffler solved my problem! Flows well and is a true 2.5". -Inlet to outlet Not disgustingly loud Just the perfect smooth sound that sounds great and doesn't scream "I'm a teenager who needs attention."
