    17395 is rated 3.0 out of 5 by 3.
    Rated 5 out of 5 by from Easy install, deep tone I bought this exhaust kit to replace the old stock exhaust that had a Flowmaster muffler. In it. This kit being far shorter than the stock exhaust system is very easy to install. That being said....let me caution you to heat the nuts that fasten the Y pipe to the exhaust system with a map gas torch before disassembling the exhaust. I did not and broke my Y pipe to exhaust system studs and had to grind them with a carbide bit and air hammer them out, that was a tremendous delay, but once the studs were replaced it was a breeze. Only other thing of note is that the clamps that come with the kit are not really a match for the thick gauge tubing of the muffler and exhaust pipes in the kit. I suggest using the clamps to get you by until the muffler can be welded in place. I am very pleased with the sound of this exhaust system and think that it sounds very deep and has a throaty roar to it.

    Rated 3 out of 5 by from Intermediate exhaust pipe bent wrong Got this exhaust system, very easy to put together, sounds great. Very happy with it... only problem was the intermediate pipe was bent wrong, tried every way to put it in, took it to muffler shop and the made an intermediate pipe that would work.

    Rated 1 out of 5 by from Garbage I thought flowmaster was supposed to at least be a decent product. I was wrong. Fitment is terrible.. hits the frame. Main pipe is too short and the front flange is angled incorrectly.. I’ve bought eBay exhausts that fit better than this.. utter junk.
