thanks for getting back to me....I was thinking I would probably run 2.25 on this one....2.5 would probably be over kill on this motor N/A with bolt ons. As far as the muffler is concerned I am def. looking for something that will be under $50....I have the greddy cat back system on my 4th gen, but that cost as much as my 87....I would like to get by with compete exhaust for around $150 or under....there is a guy here that put full exhaust on my brothers car....all the pipe, 2 mufflers, and labor for $75.

He just does not put cats in...hahahah....any other advice would be helpful, I would really like to hear some cheaper muffler alternatives that have a little grunt to them. Thanks
