I haven't ever installed an exhaust system. When my muffler shop told me I'd need a new exhaust and told me how much it would cost, I nearly fell over. I was able to buy this excellent system and install it myself saving $600 over the exhaust shop's estimate. When I compared the quality of the Borla system I was installing to the OEM system I removed, I was appalled. No wonder my new Borla system comes with a 1 million mile warranty. The instructions included were specific to my car & clear

Great Exhaust System

I installed the 140027 Borla system on my wife's 2003 Mini S. I only had one issue when installing this system, and that was getting the two old rusted nuts off the bolts of old system at the flange just behind the Cat.. The installation of the new system was very easy and the fit was perfect. I used ramps on the back wheels and partially jacked the right front wheel. Only needed a hacksaw for those two stubborn nuts which took a while to get off, several wrenches and a 1/4" screwdriver.
