I did the 2nd cat delete on my NA coupe and it did sound better and picked up some low end grunt. Thanks for the input.
Yes the Needswings downpipes will remove all 4 cats but he'll add 2 hi flow cats back for a grand as an option. Also if you remove the resonator on a srt-6 you'll get some drone at lower RPM's. Up to you if you can deal with that.
