    Does anybody have any insight on what the loudest exhaust set-up would be without aftermarket headers and without losing any performance?

    Two routes, neither are exceedingly expensive.

    1) Gut the cats, cut off resonators, get two lengths of pipe (or aftermarket pipes) and weld original tips on

    2) Get OVAL shaped electric cutouts. But be warned, they can "leak" because dirt/road grime/salt from winter roads/etc can get into the flanges and stop them from closing all the way. I had them on my 06 Mag SRT8 and even before I did my cam/heads and shit... it sounded like a NASCAR and I really never closed them. Only if I was close to a cop, just to avoid noise ordinance issues. They are addicting.

    Oh, and I mention oval shaped because you don;t have enough ground clearance for the regular ones. Better safe than sorry.

    If you get rid of the cats completely, will it throw a CEL? Have you gutted your cats, or know someone that has? If that didn't throw a CEL, getting rid of them completely shouldn't. I live in a no inspection state, so I can pretty much do whatever I want to the exhaust, as long as I don't get a noise complaint, but every car/truck I've ever had has been loud and I've never got one of those yet. If it won't throw a CEL, or if there is a plug in harness CEL eliminator like they make for Mustangs, I plan to chop out the cats and resonators, run new mandrel bent pipe and weld the tips back on. If they didn't go through the rear facia (have cutouts), I'd dump them at the rear axle. Old school. I may do that anyway, that's how my SRT8 Charger is. I guess I could hang some short dummy pipes with the tips on the end to look stock, then still dump them at the rear axle. Dumping makes the sound so deep and rumbly because it bounces off the pavement underneath the car. I can hear my girlfriend in my Charger 2 blocks away...sounds like thunder...
