I had that same car, just different color. A few things I can tell you, GET the diablosport tuner and run the 93 octane tune. After that it will be an entirely different animal. I did a Mopar CAI and it sounded amazing. As for exhaust, I had about three different combos until I landed on running straight pipes that dumped into single chamber race mufflers right before the rear bumper, and it sounded BAD ASS, very little hwy drone. This car is a heavy SOB in turns. One of the best things I ever did was lower it, but theres a catch. The rear shocks are load leveling shocks called Nivomats, so if you just put in drop springs, it still wont lower it, you have to use shocks from a non-SRT 300C or go for the expensive coilovers. I also put a tower strut bar in the engine bay and after that it handled like a go-cart. When mine was running at the top of her game, people were amazed that such a heavy car could be so quick. Also, after I took that side moulding off it looked SO much cleaner. Unfortunately, she is no longer with me. RIP SRT8. Theres a few pics in my album. Best of luck!
