    Rated 2 out of 5 by from You get what you pay for I bought this kit KNOWING it was cheap and likely wouldn't fit perfect but I needed an exhaust quick and my budget was running thin finishing my truck. One side for pretty darn perfect the other side wasn't bent right where it goes over the crossmember and totally through off the exhaust the rest of the way back. My muffler is almost sideways and I ha to fabricate a hanger from 1/8" plate to make it work. Besides the bad bends, the joints are too sloppy and each one has an exhaust leak. I'm going to drop it all and re-work it and weld it in now. If I had to do over again is buy a higher end kit or get an exhaust shop to do it. BUT if your wallet was thin like mine it can be done but I tec omen welding the joints an tossing the clamps.

    Rated 4 out of 5 by from Good quality Everything fit good except the left pipe that bolted to the header wasn't bent enough. I had to cut, bend, and re-weld it to make it contour correctly. All in all a good deal vs muffler shop charges
