    Fast shipping, responds to messages pretty quick BUT needs to ensure the accuracy and photographs of what they are selling. They are a good seller although the item I received was not as pictured and expected and required. They provided me with a fast and honest response. I would buy from them again but ask a few questions like is the photo accurate. Thanks.

    poor design, was not a simple bolt up system, I had to have a exhaust company cut and modify the parts so it would fit correctly

    The flowmaster tubing was to big to fit on the stock header pipe, That had to be welded on .The muffler was hitting the cross-members, so the piping had to be cut and modified to fit correctly between the frame cross-members.

This system was supposed to be a bolt up exhaust. After two nights of trying to get this exhaust on my new jeep I had to take it to a professional exhaust shop for them to cut and fit and weld together this system. I called flowmaster and they were unhelpful and told me that cutting and welding is normal to install these. After the exhaust was professionally ...
