My Vette has no cats and dual mode NPP mufflers. With the flaps closed, I can see over 9.5 psi, but the power goes way down when boost and exhaust back pressure go up. I wish someone would step up and make a dual mode muffler for the Camaro.
I appreciate your willingness to discuss your cam specs. Most shops won't do that. I won't do business with those that say, "Trust me, you won't have any idea what the cam is, but you'll like it!" I'll probably do the TVS install myself, but I'll give you a shout on the parts for cam,valve train, and exhaust upgrades.
I would say the exhaust is more restrective on the Camaro, a dual mode exhaust would be the ticket, I bet someone has one in the works.
We are really ramping up our Camaro offerings and almost have as many Camaros in the shop as Vettes, including 4 presently getting Magnachargers.
Let me know if I can help you with anything, I would sincerely appreciate your business.
