Pitty Nameless still has that torque dip though, but otherwise they also have quality product.. just that in my eyes ace is better  . No torque dip, among best welds i've seen, mandrel bent, low angle collector. Where are flaws, damnit? |
I originally looked at PTuning’s 4-1, but I think I was a bit naive to want that header just because it made the most peak horsepower of all of the ones I’d seen. A header with a strong midrange that can hold torque down to redline without dropping off too bad would likely make the biggest difference in acceleration, as opposed to one that only makes torque at the higher RPM range (I think).
However, I’ve seen some people that run a 4-1 header and use a shorter final drive ratio to give the car that added “torque” feel.
