I actually ordered one from Autoanything off eBay, then needed a 2nd one so ordered it direct. My order was late due to MagnaFlow issues, but Autoanything was flawless. I've saved their website for future business.

Sounds great. Quiet enough to be comfortable while cruising but when you give it some gas, it sounds excellent. A little quieter than I expected due to the stock headers, though.

This muffler sounds fantastic on my 1999 Jeep Wrangler with the 4.0. Deep throaty sounds that you wouldn't expect from a 6 cylinder. It also sounds great on my brother's 1974 Chevy truck with a 350. I highly recommend it to anyone with a truck or jeep!
