5 Stars   Great fit and awesome sound. LMR.com Expert Review!
By on 8/20/2014
Image uploaded by Lee C. This is by far one of the best fitting exhaust kits I've ever put on. A buddy and I had this kit installed in 30-45 minutes. No head aches and everything fit as it should. I really like the tips on these. The etched name on the tip is a nice touch. The sound can be very mellow or deep like a foxbody 5.0 if you want it. That's the great thing about these is the adjustable sound. I have these cranked all the way out and it's a nice deep tone and reminds me of my old foxbody 5.0. There is a slight drone right at 60mph, but it goes away with more speed and other than that it sounds great inside.

Yes, I would recommend this item to a friend!
