I'm getting ready to put Kooks lt's and the 3" kooks o/r x-pipe on mine... it will be flowing int a MAC 3" catback... i'm told by the shop doing the work that they did the same set up on another Terminator and it was the best sounding combo they'd heard... so i'm pretty pumped... i'd lose the catted H and do an o/r H or X... and also a good catback if you don't already have one.
I've only had the headers and h pipe on for about a month. With the headers at WOT it's pretty darn loud :-D I can't imagine NOT haveing cats. Anyway post up when your install is complete :beer:
I will be posting a vid of my new set up once it's done so stay tuned... here is a link to my current set up if you haven't seen it on the original thread:
