I'm going to go with 2 1/2 pipes, lose the resonator, and add a Dynomax Super Turbo muffler.
How should I go about ordering the mandrel bent pipes? I don't really know exactly how much I need of each degree bent piping. Any suggestions?
I did my own exhaust. It's good that your going with 2.5" pipes, but if you lose the resinator don't be expecting to sneak over to your girlfriends house without waking up the neighborhood. I bend all my pipes using a pipe bending machine and also put dual exhaust on my car (what a bitch!), but it was worth it. All I'm suggesting is a high flow cat with your system.
