i have hooker fenderwell headers in my 71 now and im going to schumacher tri y headers as i want my fender clearnce back, so i can get some bigger tires on the car. my question is how much of a power loss will i notice. the motors around 500hp. was wondering if anyone has done something like this before. thanks

That's totally dependent on whether or not the Schmacher's now become the "cork" in the system, ie. if you're running high flowing heads you could see a lose at the top end. Going to need some more info on your engine, exhaust system and whether you 1/4 mile it.
