Awesome exhaust!!! Qiuet around town but yet roars like a raped ape when you open her up. I got an honest 150 degree drop in EGT during heavy towing in the mountains which let me feed the engine even more fuel. The only downside was the labor intensive install. None of the factory hangers would line up on my 05 2500 ext cab long bed. I had to bend, tweak & relocate evry one of them. The clamps shown in the picture was not what came with my system & I had to modify them as well. All in all a great product. The down pipe turned a nice blue color from the heavy towing I do. Also I thought the giant polished tip looked awful gawdy & would probably be easy to rip off in the mountains. It looks darn good the way it is!

This exhaust sounds great! You barely notice a change from stock till you hit around 2100rpm and this bad boy really opens up. Already noticed a small increase in MPG's and swear the engine spools up faster than before. Great product, easy install, not problem matching up with factory mounts. The kit showed up without the tip, but working with XDP to have one sent out.
