What is the diameter of Mach 1 exhaust tips, I found a pair cheap but was wondering if they were any bigger than the GT's
The stock Mach 1 exhaust tip should be 2 1/2".
They are 3" OD just like the GT tips, but are rolled.
The cat-back piping is 2 1/4"
I have a pair that were cut off a Mach 1 with 50 miles..i paid $40 for them but never used them![]()

So much for doing a search over at Mach1registry. I could'nt remember what size they were either, so I looked it up and someone wrote they were 2 1/2". I had my stock exhaust taken off after a couple months back when I bought my Mach four years ago. I think 3 1/2" tips look best. I think 4" tips are too big.
