I have a 2007 Honda Civic EX and I am looking to purchase an aftermarket exhaust. I am looking at the Skunk2 Megapower 70mm exhaust... My problem is that it is for an Si. Will it still fit? Has anyone put an exhaust on an Si Exhaust on an Ex. I am also looking at the Greddy Evo2 exhaust and am encountering the same problem. Someone let me know what to do! Thanks.
