3SX / Kooks 3SX NA Long Tube Headers Non-Turbo DOHC 3000GT - QUALITY MADE IN USA!!!

Mechanic n i thought it fit perfect on our 1994 3000gt non turbo front wheel drive (3sx suggested getting new motor mounts also which we did). But when you step on it and in between shift it hits the subframe. So now working on fixing that issue. It may fit per their engineering but when you take it to the real world things may sometimes not be considered like movement regardless of how great or small. Well keep everyone posted on what we had to do to fix this.Update: we had to cut a notch in the subframe.
