I bought a borla CBE brand new for 500 shipped (so happy) and will be installing it tomm. I know they were made for coupes but tons of ppl run them on the sedan. After some research I've found a lot of ppl saying they have "heard" either one or more of the hangers needs to be relocated or ~4" needs to be added to the exhaust for good Fitment. Id like to know definitively what needs to be done so I'm not wasting my time reinventing the wheel tomm. I'd like to save some time and hassle by getting a good answer first. Please help me out ppl!!
