ive gone through 2 flowtech x pipes. They dont fit for *****! They are fine and dandy at the headers but when it gets to the catback they are extremely close to the ground. Having a lowered car put that section about 1" off the ground (literally). I tried contacting Holley and flowtech with no luck. I had to spend $100 to have the exhaust modified to fit right. The headers are ok but the X pipes and the manufacturer are duds.
