That is also a Power Pipe from AFM (intake power pipe) not sure how much it is alone, it has provisions for the race bypass, I am not sure if they make one with out it, be best to call.
Good luck using the STB, most blowers car require them to be modified to work, sounds like your best bet is to get a stock alum
Vortech pipe. Here contact Spence Hart
