I purchased this a few weeks ago and have had it on since. It made a big difference in power and sound. The turbo whistle is quite a bit louder. The fit was really good. Came with new hardware and a gasket. Love it, now I just need to change out my 4 inch Flo-Pro with muffler for a MBRP 5 inch straight pipe.
