i would go buy 2 4" band clamps for it. reusing the stock clamps sucks if you can even get them off. also the band clamps seal much better. i bought 2 for 11 dollars from local truck shop.also you will probably have to cut off muffler with sawzall.it sounds awsome though!! my mileage dropped cause i rev every gear out to hear the truck!!
