The mods list in your signature say you're about to do the DP/RP. That's a good next step. You might want to hold off on deleting resos and the muffler until you see how much louder and how much drone at 2500 rpm you get after that, especially when decelerating.
I love the extra power from the DP/RP. But I had to actually ADD an additional reso where the RP is just to tame the droning. I just got tired of the splitting headaches in daily driving.
I can't imagine driving daily a car with 3 inch DP/RP cats delete and no resos or muffler. And I would be a cop magnet for sure.
