With the Ramair and Viking exhaust (full system) Plus proper tune,what should I expect in horsepower and torque gains over stock.? Ramair ordered this morning,waiting on call from paul on Exhaust.
 
It depends on the size of the header 1 or 2 pipes and how good the tuner is. Anything lower the 155 and well I would be wonderimg about my cam timing
