The aftermarket OEM replacements are all crush bent. They are a downgrade from stock. Magnaflow has a replacement high flow cat (the likely source of your rattle) and a performance cat back. You can buy both sections for less than the cost of the Supersprint cat back and the fit is perfect. It is however a little loud. I have a customer that had the full Magnaflow exhaust but replaced the cat back with a Strommung unit to quiet it down a bit. If I can help just give me a call. 772.215.4069 Sent from my iPad using Tapatalk __________________ SUPPORT 318ti.org! CLICK THE LINK ABOVE!
