Just fitted the Gytr Complete exhaust system to go with my GTYR filter. Man, it's loud!!! Can feel the difference in power too. I've ordered the PC3 from Fuel moto but haven't received it yet. I hope I can feel the difference when I get that on. Quads and Mods are real expensive down here in New Zealand as our Dollar only buys US $.70c. My 07 700se lists for $12995 here. Was able to get a deal for $12500 including Gytr Filter and Nurf Bars. The Exhaust and Pc3 adds another $1500 to cost to date. The wife is starting to think I love my Raptor more than her!!!
