Just curious if anybody has ever done this as well what power gains there might be over a mainfold as well as cost. Or would itb be all for show

Problem with the Top Secret set, besides the cost, is that the horns stand straight up, so there is likely clearance issues without modifying a hood.

There was a Jenvey prototype posted awhile back too I think--if u search for it. The Jenvey set were more angled and provided better clearance. Not sure how many got this setup beyond the prototype stage.

U would also need to switch to a drive by throttle cable, a good ems, good tune, etc...

You don't hear much talk about ITB's on the VQ, probably because the cost is high (for a properly running setup) for the gains returned (although I'm sure the throttle response is great).

 

No. It is impossible to do....
