I purchased a mac off road pipe for my 03 and i have had nothing but trouble.i have had it for three months it leaks on both sides of the manifolds.we have tried everything to get it to stop. talked to mac on it and they said they would not do anything to help me the guy i talked to was mike he is a real prick.so i asked to talk to the owner and he said the owner dont talk to anyone he is to busy to.he said that when i welded the pipe together i voided my warranty guess what they are the ones who said to weld it.this is not the first mac product i have had trouble with but i will not have anymore beacuse i will not ever buy from them again.oh guess what else the prick said. dont buy bassani they cost to much but they do fit a little better.so all you buyers looking for exhaust think twice before you buy mac. :bash:
