Buy some mandrel bent 2 1/2 tail pipes if your local shop does not do mandrel bends. Decide if you want an H-pipe or X-pipe and have your local exhaust shop fab it up. Muffler choice is very subjective but for me I like the H-pipe with a chambered muffler and the X-pipe with a straight thru Muffler.
Just curious, why the H-pipe/chambered, x-pipe/straight-thru preference? Did you notice any difference with popping on decel or was it simply tone?

With unequal length manifolds or shorties, it's not like it matters whether he's running 2 1/4" or 5". There's not going to be any scavenging to speak of, and he won't be restricted by the exhaust pipe or mufflers.



However, with a good set of Tri-Y or full length headers, 2 1/4" would make a difference. So would 2", but they'd hurt the top end unless it's basically stock. Tuned exhaust IS a thing. =)

Ended up going with the JBA 40 2650 full length 2.5" exhaust system.
Thanks.
