well my grandfather has had a 06 magnum R/T for a while now.
The only thing hes done to it it take the second set of mufflers off to make it a little louder.

Im trying to talk him into modding it a little, maybe a better exhaust(I llike LMII), some bolt ons, ect...

What kind of stuff can you do to the magnum?

Thanks

JD

the superchips flashpaq was a great mod for the rt.

Thanks,
what kind of gains do you get with the flashpaq?
