Read this Link then research the terms and it should give you a good idea. Link
HINTS: 1. Ebay is not a mod guide 2. Buy the JWT intake - end of discussion 3. B&B and Labree are both good exhausts - make your own decision 4. Some say there are fitament issues with Megan racing pipes but the price makes it worthwile for people who don't have the money for GD items. 5. Like #3 - you make the decision between ASHSPEC ECU and JWT ECU. 6. jeez this could go on forever.......good luck
