will a mac cat back fit the gt exhaust holes?
 

I am taking off my v6 bumper and installing a gt rear bumper. My question is will a cat back system like the mac or pypes line up with the stock gt holes?

Well.................................














Yes!!

Any exhaust system you get for a GT will line up with GT bumper spaces.. I beleive. =x

Remember..v6 is the base body for all mustangs.. so there isn't a spacing issue on things such as that.

-- feel free to correct me if im wrong --

You're right. The GT and V6 have the same body outside of the obvious cosmetic differences. Make sure you either buy the adapter that converts your stock y-pipe to the GT style exhaust, or you get midpipes that fit on a gt-catback because it will not fit on your exhaust set-up if you do so.
