You'll love it and yes it is loud so be ready for a huge change... I was totally shocked when my buddy started the truck up for me and I stood there shocked. :rck:Thanks alot guys! Looks like I'm going with no muffler and a cat delete pipe....im excited to get to work.
The CTDs didn't come with CATs till the 600 in 04.5.Violation of Federal emissions laws to remove the Cat FYI.
The OP talked of removing his cat that is why I replied as I did.I removed the muffler but left the CAT on my 04.5 and it was good. Would I have liked it without the CAT? Probably... but I didn't remove it because of thinking ahead down the road and didn't want to possibly run into any problems.
And if you don't have an intake... get one. And if you haven't removed the silencer ring then do that too.
I have a couple of vids in my Gallery of both the intake and exhaust.
