I also have a 07 Charger Daytona RT in Sublime with a SLP Loudmouth exhaust. I had thought this car handled very well and was fast. Until I got my new Challenger.

The Challenger seems to just have so much power and handles more like it weighs 3000lbs. WHen I am driving around I feel like I am driving a very fast Muscle Car. Although I love my Charger it just doesn't feel the same.

The exhaust on the Challenger is no where near the sound of my Charger with the SLP but I plan on adding a new exhaust soon to bring out the sound.
