Not worth the money
I purchased this exhaust system thinking it was a better option than piecing my own system together. *big mistake. The pipes coming off the headers were not bent correctly. I had one side that sort of fit and 2 that didn't even come close. If you can't weld…do not buy this kit. I had to re fabricate the entire kit on the passenger side and the driver side from the muffler back. It is definitely not a "bolt on kit". *hardware…I was missing every single nut out of my kit and the clamps that are supplied are mis shaped and needed to be bent in order to use. All in all I would not recomend this kit. I attempted to contact customer service at Thrush and was placed on hold for an eternity. Bottom line. I would not purchase this kit. I was not happy with the quality and the bends in the pipe did not work for my application. IMO it would be cheaper and less of a headache to build your own system. I should of listened to the other reviews and went with my gut…
Bottom Line No, I would not recommend to a friend
