DynoMax Ultra Flo Cat Back Exhaust with Single Exit in Stainless Steel Reviews
The kit was certainly a good price. Quadratec shipped quickly and it arrived in good condition. It was installed on my Jeep in late November of 2018. I love the slightly deeper and throaty sound note it gives the 3.8. Not too loud, but sounds tougher. I am disappointed however, that in less than 2 months, I noticed significant surface and weld rusting occurring. Not concerned form a performance perspective, but it looks bad. Both the muffler, and the tubing including the polished tip are showing rust. For a kit listed as Stainless Steel, i was surprised how quickly this showed up.
