Magnaflow Glass Pack Mufflers Reviews


All around perfection

Reviewed By jefferson c (MOSCOW, ID) Reviewed for a 1999 Jeep Wrangler —6/5/2016 7:58 PM

For a glass pack replacement of the Wrangler Tj factory muffler, this was the perfect choice. This muffler was economical, an easy fit without cutting, and it is only a tad louder than the stock muffler. Ya, if you are thinking hot rod sound, or hoping to make your 6 cylinder sound like a V8, the #18135 22" glass pack is not the one for you- get something shorter. Otherwise, this is a great choice and you wont regret it!
