Yes they will, but it will still not be as loud as the offroad pipes.

buddy of mine back in KC had an SLP LM2 system on his 03 Mach 1, and it was pretty aggressive sounding, and of moderate volume, but it wasnt too loud or obnoxious.

if you get a tuner it takes care of the CEL. so when you get it inspected and they hook it up it doesnt throw any codes. and BAMM!!! you pass inspection. it'll cost you a tuner though but its DEF worth it anyways.
