I am trading in my 2008 Mini Cooper Clubman S. I bought a Magnaflow stainless steel exhaust system part # 16855 for it back in January of 2011. The dealership that I'm trading it in to said they have no interest in the exhaust so I removed the Magnaflow and installed the original exhaust. I can't believe the difference the exhaust made now that it's back to stock. The Magnaflow system definitely improves performance and it sounds great! I'm asking $500 for the system and I can also install it if needed as I own an automotive repair shop. Contact me if interested.
