intake leak?
 

Ok I just got finished putting in my magnus 75 mm manifold, and it sounds funny, but cool. I thought if it was a leak in the manifold the car would run like shit, like it has a boost leak. But it runs fine. So I don't really know if it is suppose to sound like that or not? (i'm running the stang throttle body)

It will sound a lot differently, simplest way to check is by doing a boost-leak check which is always a good idea after working with the induction track.
