Kind of a quick question. What is the stock exhaust pipe size on the cooper s? I can't tell if it's 2.25 or 2.5 inch. Looking to throw an inline muffler in....any info would be great.
Naw....no need for a new exhaust. I chopped off the two mufflers under the *** end....now just need something to get rid of the howl at freeway speeds! lol gets to be a lil' too much after a while
