Header, Intake, & Exhaust - 2000 si headers

hi,
i just wanted every ones opinion as far which headers are good.. i know i want 4-2-1 headers just dont know which name brand.. also will these set my check engine light off..(dont want that to happen.. happen with my rsx type s.. and cars that i had already beat up came back to beat so thats a no no...) thanx

look into some DC sports 4-2-1. and just remove the negative battery terminal when installing it. It resets the ECU so the CEL shouldnt come on

DC Sports is good, but really pricey...
Hedmen and Megan Racing are about the same quality for half the price, but the Megans aren't carb-legal in Cali as far as I know...

Also, there's only one header in a 2000 Civic SI ;)

thank you for your input.. i know theres only one header on the car but theres many brands of headers..(not trying to make fun of you or anything just explaining why i wrote it).. i asked this question because when i had my rsx-s i only thought that dc-sports and toda headers were the only ones for the type-s.. but now i fought out about jaskson racing/ sr-s/ buddy club headers... i just want some good ones.. because i have typr-r ones but i want a one piece

Just a question related to this.

I was considering getting some spoon headers 4-2 then a 2-1 downpipe. But i'm kindda wondering how's a full exhaust built, is it as followed:

Headers > downpipe > catalitic converter > b-pipe > muffler ?

I would love to go spoon from headers to muffler (i know i know $$$). I know they don't make catalitic converter, but i could get a performance cat to replace from a good brand.
