extremely nice gxp! i dont have money for a turbo but after exhaust and the overkill tune thats probably all im gonna do to it performance wise for awhile. I'm waiting to do my exhaust until the new headers get released for purchase. Their alot cheaper than DT's and from what ive read better. Then im gonna do 3 inch to the y split then go down to 2.5iche to the mufflers. the tips are gonna be 2.5 inlet and 3.0 outlet. but a cutout will be coming soon as well and when you say you put yours before the cat...can you take a pic when you get a chance of where at ?
