Hi Everyone

I've been trying to find a MAC cat back that is all stainless steel in ontario here. It seems like all the suppliers are not making it anymore. I'm not sure what the size of it is but the catback has 2.5" piping. I was wondering if I just get 2 stainless steel MAC mufflers is it going to sound good with the stock piping? Also what is the stock piping size? What size muffler should I get?

ive never seen any mac cb in ss, but im sure if you just put a set of mufflers on, it would still sound good. i think the stock size is 2.25

Yea just do the muffler swap
I actually saw the Mac all s/s cat back advertised awhile ago
Company is very strange in availability of their products. Took me 2+ years to find one of their chrome battery covers.

Thanks for the help guys. Thats good to know the size is 2.25...I guess going from 2.25 to a 2.5 catback won't make much of a difference. I'll post back when I get a hold of them.
