I just landed an 80 series muffler with the tailpipes for 40 off my local craigslist. Its 3 inch inlet 2 2.5 inch outlet. Now all i gotta do is figure out how to get the exhaust from the headers to the muffler...

 

You should be able to find an appropriate S-pipe and I-pipe at Summit.

 

my local exhaust shop is custom making me a 2.5 x 2.5 x 3 inchy pipe and running custom bent 3 inch pipe back to it fo 100 bux!! How do you guys think it will sound? my cam specs are 218/224 270 adv. duration, .462/.469 lift @.050.

the cam also has a 110 degree LSA

 

I've got the same thing for anyone else who's interested (plus shipping, of course).

Some people like it. I got tired of it, but put up with it another 6 years after that, anyway. It'll be loud, a little quieter if you have a cat.
