I saw an ad in SCC from a company called Air Dynamic Racing Inc.
They've got "Kits" for pretty good prices.
1 kit's got a CAI, Tenzo R muffler & headder for $349. There's other stuff too, light kits, suspension...The whole 9.
I just ordered a set of Indiglo guaged from em for $50 bucks.
Here's their link:
