muffler case size

Theres like a million that'll fit.

so what are they? or specifically what are you using?

Mine are custom stainless, 2 1/2" in/out, the exterior replicates OEM, but little restriction inside.

They were made specific to my application, by a fabricator who now has started his own exhaust company in Elmira Ont. Close to home for you Matt.

hey giles,
i remember you fired her up for me, sounded good with those muffs! Ive really grown fond of the sound of Borla xr-1's, so im going to try and run those, but trying to decide which case will fit in there best is kinda hard...thought id see what everyone else runs
