Well I finally got my PROM 87/WMS combo on. From the sotp it is a real nice improvment. The engine howls know and it really is a nice improvment. The big differeance is the front end of the car really lifts up now.

On the down side I can really hear the noise from the Tri Ax now.

My Mac H pipe is on route at this time. I hope they complement each other (more air in and more out). I will dyno after the H pipe is put on.
