Hello all. My name is Derrik. I recently bought about a month ago a 2011 Dodge Charger R/T AWD. Iv always been a ford guy but moving to the mid west I needed an AWD vehicle and I wanted a sports car so I found an AWD Charger. I have a few questions about mods as I’m new to the dodge world. With mustangs, they have websites like latemodelresto and americanmuscle to order parts for. Do they have any good performance parts websites for our cars like such? I’m wanting to do a full catless exhaust with probably SLP mufflers. Where can I find good performance parts at? Also, with it being AWD, is it possible to change the gear ratio in the diff’s? Iv always had manuals so autos are also new to me, as also having and AWD vehicle. Going catless, I’d imagine I’d need to get a tuner/tune to prevent the CEL from coming on? Or are something like mil eliminators an option for the application? Also with these cars, are tuners worth spending the money on? Any other good advise from you all on good performance mods will be very helpful. I’ll also be putting lowering springs on it as well. Thank you all!
