Since you have the 4-dr you should be ok removing the resonator, its just that on 2 doors like mine it drones at certain rpms. Something to do with the acoustics and harmonic frequencies of the 2dr vs the 4dr. Anyways, I am pretty sure that the measurments for the stock pipes is 2 1/4 ID, although measuring it yourself wouldn't be a bad idea just to double check, and it will only take a second. I would go ahead and scope out the whole set up too, just to get an idea of what you're gonna need and how much room you have to work with. Get a plan going of what you are gonna try and do and make a list of stuff to get at the parts store BEFORE you start cutting stuff up, trust me I learned this the hard way, lol. Don't be afraid to ask if you have questions about stuff.
