Red Rhino: I did not buy the Force II system. I removed (cut) the large single "suitcase" behind the cats and welded straight pipes. I sounded Ok at idle but when I accelerated to pass someone, I sounded too raspy and loud for my taste. I ended up welding the suitcase back to the original location. The R/T now has 8K miles and it beginning to sound OK. I may purchase an aftermarket muffler system later but for now I have others vehicles and toys to upgrade too.

 

A friend of mine did that and had the same result. Sounded great at idle, but under WOT it sounded like crap. Very raspy and loud. And not a good loud.

 

I have the American Thunder system and it sounds great at startup and idle, and sounds sick at wide open throttle. I LOVE the sound.


My only (STRONG) recommendation would be to fully paint the pipes in ceramic high temperature paint before you install. The material is not great and will start to rust almost immediately. I'm a year in and will need to drop my whole system to paint in the spring.


If you do this (paint ahead of time) you will be really happy.
