I love my borla stainless steel XR-1 race mufflers. They sound great, have a lifetime waranty, and very nice construction too They flow way better than any other chokemaster or chambered style muffler

If I really had it my way id have bullets on my car since they sound awesome and flow better than anything...but driving two hours to the track each way at 3000rpms would probably make me deaf in about one trip lol
