Wouldn't that mess w my torque bc of the loss of backpressure

 

maybe a little......

 

I've got a 40 series on mine. I love that thing. I drive through a lot of tunnels here in Southeastern VA, and it sounds awesome echoing off the walls.

 

I just had a 3" si/do 2.5" super 10 set up on my 06 hemi ram today. I'm pretty excited and happy with the setup. Unfortunately, I am now certain all of my neighbors in my apartment complex hate me.

The super 10 on my truck sounds identical to this '04 with a super 10 on youtube. http://www.youtube.com/user/hotrod7687 I felt somewhat sketchy that the truck would have some bad popping or backrap in the exhaust when the RPM drops after a rev but it has none at all. The drone is quite bad, but once the truck hits a cruising speed and drops into O/D it goes silent.

Forgot to add - no noticeable loss of low end power.

 

I am a big fan of the cherrybomb extreme..... its alot louder than my buddies 40 series he has on his furd 150, but i have a 4.7 and i hear that they sound meanie on a 4.7 than the hemi but idk for sure...
