I know many of you want me to just throw back on the stock manifold and cats, but that is not going to be what is happening.
This setup is working very well, we are running an 8PSI pulley which was designed and tuned for stock manifold and cats. Nothing is disappointing or "wrong" currently, this is about what I expected with my setup. This puts us in a great position to work on this car and provide the best possible setup for what we have, and improve this platform beyond what anyone was expecting.

My setup from the start was not going to be an exact 1 to 1 copy of what GTM is producing. I have decided to go my own route with the long tube headers, and Sam at GTM is helping out tremendously on this and we hope to move forward with some great results soon.
