Pewter Metallic- 2000 Pontiac Trans Am WS6
HP gain from Headers
I have had 3 fourth generation Trans Ams,two with headers and the one i currently own which has no headers,i feel the difference between stock headers & aftermarket performance headers seems like my previous LT1 & LS1 produced more power with the addition of the aftermarket performance headers,my question is how much horsepower does the aftermarket performance headers actually add to the car? I found a set of edelbrock stainless steel headers with Y pipe for $325 these are used though,BTW my previous cars had full aftermarket exhaust,my current car has Borla exhaust

Tune will effect this number greatly.
So will the other mods on the car.
Basic bolt-on car without tune? 10-15RWHP.

True, didn't take that into account
Most gains will be up top
