Ap•March 18, 2018
Muffler had a pin hole in weld around the case when purchased this is the first out of the 6 flowmaster mufflers that I have purchased overall good muffler a lot better than the dynomax welded muffler that fell apart on the inside

My truck sounds awesome with the new muffler and exhaust. I went from a 3" flowmaster to this 2.50" flowmaster. Thanks
Good But didnt fit

Great product, sounded good but didnt fit my 91 s10 2.5L, Pipe was smaller than the exhaust so I'll be selling it but it arrived quickly in good condition 4 stars.
