I bought the Calamini Cat back for my s/c. Living in NY I would no recommend you buy it. It was on since the end of last summer. I only have 12,000 miles on my car probably 4 is with the exhaust. Now the muffler is completely rusted out and the exhaust tip is hitting the rear fender and rattle like a bitch. If it aint Stainless, dont waste your time, living in the northeast we are screwed. Magaflow is comming out with a cat back in 6 weeks.
