Review on Walker 53529 Ultra Domestic Converter by James Fisher

Worked on 04' Jeep Wrangler X First ordered with rear (3rd) roller, it didn't fit at all. This system is completely OEM except for the rear cat. I lengthened the pipe and continued with the 2.5" all the way. No more checking engine codes/lights and you can see the difference in MPG and horsepower!
