Only on the trucks. If it was effective, you would think mother GM would have used them on more appliacations

Just think what could happen if it fell off, all the damage it would cause. There must've been an extreme amount of testing to come up with this mod. It would be great to dyno it against a standard baffle to see if there is a difference. Good post.
