I don't know about removing the resonator bud. I would just go with headers and leave the rest of the exhaust alone. I've read that removing the res will give you a raspy tone, and all the restriction is up front, manifolds/u-bend...that headers would eliminate. Do some more searches, browse around a lil more and read up on other ppls expereinces, what works/what doesn't, and learn from other ppls mistakes. Take your time, you can really save yourself alot of money and time by just reading up on things.
