Haven't had any problems with mine. Here is what I would do though if you get the Borla Hush. The flange that comes with it is 2.5", find somewhere that sells it with the 3" flange as well. This way, if you don't have an upgraded downpipe, then when do you, you'll have the 3" flange to swap, otherwise, you won't be able to hook the Borla to your downpipe. Also, where I bought mine, they sold the hangers for like an extra $30, so I got those as well. Was real easy just to cut the old ones with wire cutters to take them off, and use some type of lube (ie: PB Blast) to put the new hangers on. It should only take 15-30 minutes to put the exhaust on, it really was that easy. I was able to drive the car up onto some tire ramps from the front, and do the whole exhaust that way.
