best sound yet that I had - open pipes - too loud to drive without getting pulled over or going deaf but it sounded so good. Very deep V8 burble and popping on deceleration and at idle, opening the gates of hell scream at high rpm.
no cats, no resonator and stock muffler = too much buzzing
no cats, no resonator, flowmaster muffler = better but still buzzed from 2k to 3k rpm
no cats, glasspack at resonator location, flowmaster = even better but still had buzzing around 2.5-3k rpm
no front cats, high flow main cat, glasspack, flowmaster = even better but I still have a little buzz at 3k. My current setup. Got the low end torque back with this setup too. Harvey was right - the main cat makes a difference.
Still searching for the perfect sound. I think glasspacks where the stock pre-cats are would completely kill the buzz but unfortunately they would probably die from the heat rather quickly.
