Hey Brian,
A week ago i bought an 05 Magnum RT and i did lots of searching and asked a few questions here on the forum. I just picked up my car from the local shop here in Miami (GAW Racing) and i had the following installed and it made a world of difference..!!
I got a Borla exhaust from
www.borla.com part#140112, i also got a K&N cold air intake from
www.k&n.com part#57-1542 and a superchip from
www.superchip.com part#3825. I'm really happy with the set-up it feels like a totally different car.
Hope this helps!
