Well, I put a gauge on the little tube for the auxillary ports. Did a few stationary and around the town runs and I am producing almost no back pressure in the tube.

As I drove around I noticed the guage barely even twitched until 6k RPM and then it produces about 1 Psi.

I stripped a bolt in front of the main cat so there is a pretty good exhaust leak.
Although there is still at the least 2 Psi coming out the mufflers.

Any ideas as to what is causing this?I was thinking that the little J scoop for the line broke off inside the cat and the air is just passing by instead of ramming some through.

 

that exhaust leak is killing you.
