i had the exact same setup---i cut out the resonator and it made a huge difference, then i got so used to it, i ran true dual straight pipes and couldnt get used to it and ended up putting super 40 flows on it.....sounds superb.....if i may say.....if you want to spend more money or i guess if your willing to, get a good exhaust shop to run true dual straights and then shop for mufflers.....put the mufflers near the hottest area of the pipes after the trucks been runnin for a while(where the exhaust pulses stop, youll get the most power) if you dont want to spend much more money just cut out the resonator
