I think, as with everything, I just have to spend more money and keep experimenting.
I have longtubes, 3" off road H, pypes m80 resonators. I was running FR500 mufflers, have used these with the stock manifolds and cats/midpipe as well.
I seem to have a different opinion of the 500's than most people. The exhaust note is high pitched with a terrible rapping at 2800-3500 with any throttle (boost) at all. I think most people with these are n/a. I liked the shooting ducks on decel and shifts, and scaring the living hell out of everyone, and hurting my eardrums under overpasses, but hated the rapping all the time right when I was just trying to drive normally here and there.
Put my factory mufflers back on and with the m80's the car sounds pretty stock. Deep roar with now audible blower whine and with the 69mm pulley, tire squealing noises!
I had a central merge designed, a pro chamber, and will try this with the 500's to see if I can deepen the tone and kill the rapping. It will essentially change the length of the exhaust as the sound waves see it. The rapping has to be constructive interference.
Any other ideas? MBRP's are straight thru, but cheap. Corsa extremes?
