Wow scotty ur an ass. Yeah I know to use a ruler, exhaust hangars are made of different materials and lenthgs if u seen my original post I knew I would need a longer hanger and maybe something firmer to keep it from hitting diff. But anyway none of the websites mention length of hangar just hole size and some say .75" longer than oem. That was reason for post is to see what hangars gave what clearance.seeing as they are multiple brands of hangars I wanted to know what to get instead if wasting my money on **** that wont work the I want. So scotty maybe you should take a class for aholes that cant seem understand what the context of a post is. So go bash the subie newbie somewhere else and let this thread die.
