D series header ques.
How many of you guys have used a 4-2-1 & a 4-1 header on a D series? I just installed a 4-2-1 on the wifes car & yes it's better than the stock manifold. I've heard the 4-2-1 is best for bottom end & mid, while 4-1 is best for mid to top end. Whats your take?

4-2-1 is better for midrange power, 4-1 improves later on in the powerban (high RPM). I got a 4-2-1 just because it was a good deal and I have heard of people having clearance issues with 4-1 on EF chassis. [EDIT: didn't realize what forum I was in... oops =p ]
