Has anyone had any experience with flowmaster mufflers? If so, what muffler did you use, are you satisfied, and did you notice any increase in performance?
I have quite a bit of experience with Flowmaster. Their
Flowmaster® Part #: 817674 sounds completely awesome on these Pentastars! (in my opinion). Listen for yourself...but to answer your question about performance, well...I would recommend buying an exhaust that is pleasant to your ear. If you're buying to look for performance increase, you most likely will be disappointed no matter WHAT you buy. Increases (if any) are very negligible. Instead, buy it because it sounds good!
This kit completely tucks under the Jeep and exits
out the back. Additionally, you wont blow exhaust all over yourself on those dusty trails like the down-piped kits that exit before the axle!
This series (American Thunder) has pretty aggressive outside volumes. But no more than the Dynamax setup that guys around here are running. You can get this same kit with an additional resonator called the Force II.
I also run the 44 series Flowmaster cat-back kit w/resonators (Force II) on my Supercharged 2012 Challenger
..here's an install vid of how easy this thing is...
