That car makes that GP look like right at home on there. I give it two thumbs up.
For the exhaust, if you can get the money together skip the SLP exhaust and get some Borla Mufflers and a cat from www.justmagnaflow.com
(the SLP cat is WAY overpriced and flows practically identical), a u-bend delete, and a high flow resonator. You will not be disappointed, I gauruntee you that much.
I have talked to a few GP guys who have run both SLP exhaust and Borla mufflers and they all say the prefer the Borla hands down.
