5Competely satisified with muffler
By Maddog
The muffler arrived quickly. I removed the stock muffler on a 2011 Jeep JK and installed this muffler ahead of the rear axle next to the evaporator. There was not any size issues and the Hushpower has a reduced heat flow technology built in. And best of all, the sound and power gains are great. I am very satisfied with this product.
