I put on the Boss 302 H-Pipe with the side pipes and QTP cut outs. Sounds awesome. No drone. Not too loud with the cut outs open but I can close them and go back to stock for a quit ride when my rib is riding shotgun.
However, I might try a different set up if I delete the cats. I've been thinking of adding a blower eventually and the cats would be too restrictive and taking them off might make the straight pipes on the side too loud.
