what size pipe for true duals?
i have 3'' H-pipe dumped with 1-chambers at the moment, but when i get my LT's installed and cats taken out, i want to switch to 2.5'' because i need to get it re-run anyway since the shop that did mine left me with hardly any clearance and just didnt do a very good job. would there be anything wrong with fitting the 3'' inlet/outlet diameter mufflers into the 2.5'' pipe? sorry, didnt want to hijack the thread

I have 2.5's w/x-pipe and love them. Dutinsss, using the 3" mufflers would be fine. The 2.5 and 3 inch mufflers are actually the same size. They just have different diameter inlet/outlet flanges welded on. Just use a 3" to 2.5" reducer and demensionally, for clearance issues, it would be the same as just 2.5s.

only reason is i got a real good deal on the whole setup off of a 03 cobra and modified it, but for 50 bucks and it was barley used why not.
with the 408 tho i'm redoing the exhaust to 3in and gonna go over the axel instead of dumping it
