"How do you know the headers were any good? Ive tested headers that were a 75 HP loss."
A 75 horse loss eh? :wtf: They must have been smaller tube than the stock manifolds.
Nope. Name brand junk. I've said this before but it's worth repeating here.
I've seen more headers LOSE power than make it. If you don't put the engine on a dyno and test you wouldn't know. Or worse yet, you dyno the engine with dyno headers (that is just dumb) and then wonder why the dyno numbers don't match what happens at the track.
Testing between good headers there is very little difference.
Testing between a good header and a junk one is huge.
