I got the Calmini cat-back and header about a month ago when I put in my lift.
It works pretty good though it was a pain in the ass to install.
They don't send you enough material with the kit because they recently changed the design and I think they are trying to sell of their stock before they implement the design change. (or something along those lines) :-/
So if you order it your gonna have to find a two foot piece of 2" exhaust pipe and bend it to fit between the Cat and the flange pipe that comes out of the muffler.
And the kit is no longer a full bolt on kit. You gotta weld the collector to the cat, then you gotta weld the piece of pipe that they dont send you to the other side of the cat, and to the flange pipe that comes out of the muffler. (like I mentioned above)
Make sure you bend the pipe that runs from the cat to the flange pipe perfectly or else it tweaks everything out of line and it's a bitch to attach the pipe to the hangers. ( I had to do it twice before everything sat right)
If I were to do it again I would just order the header and have a local exhast shop do the rest for me with a flow master kit. Since I live in Canada it cost an arm and a leg to get that stuff shipped up here.
But don't get me wrong. With all the install probs set aside, its a great system. Huge power differance!
