IMF headers...
just wondering, but how do these affect drive-ability? Does it remove a lot of low-end power or torque? I know hp numbers up top are nice but what about down low is what I'm saying?
Thanks

I am not blowing smoke, i am not using it as a marketing tool, its truly what it feels like. I owned a 92 SC400 with these headers on it and i couldn't imagine going back to stock manifolds.
As for low end torque, it goes up, way up. Off the line it feels a lot more then a 20hp gain.

thanks for the PM Chase.
I'm fitting these headers to hopefully solve a fitment issue with other available headers.
I have a W58 manual conversion , and Rush headers wont fit , with out going to a hydraulic throwout.
IMF headers should hopefully solve this fitment issue.
I actually prefer 4 into 1 design as well rather than tri-y designs.
I have alot of experience in bike racing , and 4-1 designs are alot better for top end power , but don't seem to lose as much on the bottom as other designs.
It's true what ever you gain on the top end you lose from the bottom , but 4-1 design seem to lessen this to a degree. The scavenging effect is increased in 4 into one better than tri-y's collecting the wrong cylinders.
4 into one or flat plane crank , or hideously long primaries merging under the engine , simple really.
thanks again Chase.
