We're going to lose some low end torque with these headers, because any time you reduce back pressure, you will lose some low end torque. And it doesn't matter if it's headers or HFCs or test pipes or a cat-back exhaust. All of those components reduce back pressure, hence all of those components reduce low-end torque to a degree. Here's the thing. Low end torque is typically anything from 0-2500 rpm. As far as I'm concerned, what happens in that range is virtually inconsequential. |
+1. This is my take on it as well. I'm unsurprisedly expecting a drop in torque in the low rpm range vs a stock car, given how free-flowing my exhaust is now, and I could really care less. I actually do drive in that range a fair amount, as this is my primary car and I have to fight Houston traffic sometimes. But I only really care about HP/Torque gains up in the good rpms (4k-ish +), which is where my tach will be staying when I care about performance.
