kind of curious too. I am down for some added sound and power but would rather drop my money on tires for the track rather than an exhaust .

There really isn't any parts. Just got to the muffler shop and tell them to remove everything from the 2nd cats and back. They will be able to weld in another couple pipes in its place. Unfortunately, I can't remove the secondary cats since in GA no muffler shop can tamper w/ emissions parts. Ugh!

Don't remove everything. All you need to do is have the secondary cats removed and replaced with straight pipe and also the mufflers. Do not remove the factory resonator...I could tell a huge gain in performance when I did mine. The car pulls so hard now....haven't raced anyone but a SS camaro from a 60mph roll and it turned out bad for him....I pulled 3cars easy!
Are you cutting the secondary cats and the mufflers in a way so you can get them rewelded if need it?
