Where the heck are you guys coming up with these HP numbers for aftermarket headers? You can't assume this number or that number because the stk. exhaust manifold looks restrictive. The stk. exhaust manifold may not be restrictive on a stk. setup. And that would include a Cold Air Induction kit and tuner.
Granted there isn't a lot of information on this stuff most likely due to the vehicle not being noted as a performance vehicle and the majority of owners are not going to modify them. So we have to wait until someone or some manufacturer decides to do back to back testing and then hopefully they share information.
