Great cat back system!
This is one nice cat back system... Very high quality and great fit. I am super picky about exhaust sound. I don’t like it too loud, too raspy and poppy or too obnoxious. This system sounds perfect. Great rumble and sound under load. There is some drone but I can live with it. My Power Wagon felt a tad more responsive as well. I haven’t gone through a tank of fuel yet so I don’t know if there’s any MPG gain. This is a 4” system so the exhaust tip is...large...its attractive but its begging to drag something on a trail. Very happy with this system.
