Am headed to the local exhaust shop tomorrow. Read in the LXforums that the flowmaster 40's in place of the suitcase muffler gave a great musclecar sound at WOT but left the interior quiet during normal operation. Oh yeah, and the resonators were kept in place. Just wondering, because I don't remember previously reading, if anyone else has worked this setup on their Chargers? I want the musclecar sound without having to yell in competition with interior drone. If anyone out there can give me an opinion....and I know ya'll can ....please do so. I may even just put straight pipes on with resonators only to see what, and how loud, that is. Hit and miss until I find that perfect sound, if ya know what I mean. Thanks in advance.
