opinion on this complete exhaust system?

That's not bad at all. I wonder if my local exhaust shop can come close to that. Kepich quoted me 190.00 plus 40.00 for shipping for a 2 1/4" kit w/high flow muffler. Is the only difference between a 74 and 75 the cat? I was just wondering. I also thought I read somewhere they were also stainless exhaust in 75.
Thanks Mike
