I currently have the F.I. LTH's and 18" SS CBE.
As for intakes, I have the K&N Drop Ins and COBB Post MAF tubes.
The reason I went that route is the stock intake is actually very well designed to maximize power. So it didn't justify spending so much for a full CAI up front. That's why I didn't just buy one up front since I was modding on a budget. Now that I have all the rest done, I will be going with the Stillen Gen III's due to them having the most promise with gains, and several people having problems with Injens and water intake.
Eventually I will be getting the NST Lightweight pulley set, and once I have those and the Stillens I'll go get tuned to incorporate all my mods and pull out the last ounce of power.
Then begins the long wait before Forced Induction.
