The exhaust is very mellow. has anyone tried to take out the resonators and run just the mufflers? Im curious as to how it would sound.

I would veture to say a lot like straight pipes. If u look at corsa resonators, you would see they are pretty much a 2.5 inch pipe with slots cut near the front of the can to create the wave reflections.
I always thought the Corsa was pretty loud myself, but without the resonance in the car it was more loud for everybody else on the street.

Hey Johnny go with headers....When you take off your stock manifolds you will see up close how restrictive they are....
