Doug’s or tti headers

I'd be interested in what you've done with the engine and what your goal is. Shorties are marginally better than factory manifolds but long tube headers beat both. I've always been a fan of Doug's with TTIs a very close second. Supertruck makes a good recommendation for the Schumacher Tri-Y's if your engine is on the milder side. (Now the door is open for the velocity vs exhaust gas expansion debate; ready, go!).
