I have a 2004 V6 I am pretty sure its a 3.9L. I was wondering if the MAC or JBL shorty headers will fit. been really hard finding stuff. everything i run across says 00-03 and 3.8L; is there any diffrence between the 3.8L and 3.9L V6?
It's all internal, but pretty much everything works on it. Get some MAC LT's and a catted h-pipe and either a magnaflow or flowmaster catback. Magnaflow has better performance, but there's a general concensus that flows sound a little better.
Icant seem to find a catted h-pipe, found a catted x-pipe but it was for stock or shorty headers. I dont like flowmaster their sound or their lack of perforamce. Most likely if I dont run the steeda side exhaust i will run magnaflow
MAc used to make a catted h-pipe, but stopped due to supplier issues about a year ago. You can jsut buy an h-pipe and have a couple high flow cats welded in, that way everything will still bolt up correctly.
