Up for sale is my borla cat back exhaust. Price is $450 obo + your stock exhaust (I need it to replace the borla) Im selling this because im selling my gtp. Exhaust has been on my car for about a year now. I have a shop where I would be able to swap the exhaust onto your car for you, free of charge as long as you can do it during the week M-F After 5pm. On a saturday or sunday we would have to do the swap at my house.
