Just got a stock 06 GXP w 56K. Was wondering what you guys thought was the best SOTP budget mod. Not interested in nitrous and turbo is out of my price range too.

not a budget, but tep transmission with the 329 gears made a huge differences.
i did feel a differences when i replaced the muffler and y-pipe with a single in dual out flowmaster race muffler.
