4-1 or 4-2-1
Ive got some money and am about to purchase some upgrades for my car, and I have a question. Im in the market for some racing headers, and im wondering whether I should go with 4-2-1 or 4-1.
If I go 4-1, what kind of torque loss/ daily driveability loss / problems am I looking at?
If I go 4-2-1, what kind of performance loss / advantages over 4-1 am I looking at?
Emissions / legal issues are NOT an issue here. (Good ol' Mississippi ^_^ )
Any other input would be greatly appreciated. Thanks in advance guys!

RE: 4-1 or 4-2-1
ok. my collection of knowledge came up a bit today. i picked up a book with a bunch of back to back dyno tests on different mods on hondas. the difference between 4-1 and 4-2-1 headers are WAY less than any of us thought. its like 1-2 hp on the bottom or the top. take your pick. you probably wont even notice it one way or the other. just drop the dough on a good brand. Comptech looks solid, as does Greddy and DC. those are the easiest to find anyway.
