I saw on one of your posts that you have the K&N FIPK and a TBS how did you get the TBS to fit, did you cut a notch out of the fan shroud. Does it whistle like a Supercharger, is it worth the money? Any pics of the TBS and the FIPK installed?

 

I had a K&N FIPK and a poweraid throttle body spacer and I had to cut a lot of my stock fan shroud to get it to fit.
It only whistles when you hit the throttle, it sounds pretty cool nonetheless, but a majority of people say they are a waste of $100.00 // Not sure if anyone has done a comparison, but most just say no to it.

 

here's a pic I found and scanned from my truck:
