I was told that since we knew the back pressure produced by the stillen cat back that all we had to do was duplicate that and that is all we did. We did change the diameter of the pipes from there back as well but I allegedly and producing the same back pressure as a stillen cat back system which I thought would produce the same HP as a stillen would and the sound is fantastic.
I am so impressed in the unique sound.
Now I want to put drop in filters amd go to a tune shop in Sarasota and make the final adjustments.
I think they will back up the OEM and let me save it in case I need it.
I will keep you posted once I get the HP and TQ results back
Thanks again
