I would probably get the SLP system for the new challenger. If it the Loudmouth system, it might be to loud for me. My brother has that system on his 98 Firehawk, it does sound good, but a little loud for long drives.
I learned the hard way to be careful when it comes to the exhaust system...I had 3" dual pipes with crossovers installed on my 67 Charger. The exhaust guy thought my built 360 6-pak needed the extra breathing....it now sounds like a NASCAR racer at Daytona!
Had a nice stereo radio that I was planning to install....not needed...couldn't hear it................and yes the sound from the exhaust really works on your body if driving long distances (may change out at a later date)....but it does sound mean!
