All I can say is "WOW" I don't care what others say about the AF1, I just finished installing it on my 04 SCab and I love it! It sounds incredible, I love the WOT sound and I can DEFINTELY tell a difference in performance. I am even more excited now to get the Troyer XCal 2 and Magnaflow SISO to complete my stage 1 performance kit. As far as pricing I have seen on other threads....I won't say how much, but Troyer is now offering a special pricing package on the XCal2 and AF1 intake that is an incredible deal, much cheaper than buying them seperately. I opted to by the MagnaFlow SISO from Performance Peddler, as it was cheaper to do that than buy the complete Stage 1 from Troyer.

 

cant wait to get the af1 and xcal2 combo myself...good to hear its working out for you
