I would just like to let potential buyers know what a nice product this is. I just received mine, very prompt shipping with great communication and I am very happy with it. It is very stiff, being 5 ply, so very little flexing will occur under boost. I am currently running a 5-3½ reducer because this is the largest reducer I could find. I have an 3-3½ adapter on the intake pipe to make it work. The reducer is only 4 ply and flexes quite a bit under boost and when the throttle blade closes. This reducer should cure that, as well as look better. This post ended up being longer than I wanted but for anyone running a 3 inch intake pipe with a 5 inch GT500 throttle body this is a must have.
