Kook header question

Quick question. My set up right now is

Borla type S exhaust
Boss man
Airaid intake
84.5mm TB

What size headers should I go with
1 3/4 or 1 7/8. I'm N/A for now maybe one day go FI but no time soon.

Definitely 1 7/8 but keep in mind because the Kooks are a mid length equal length header they are much harder to install over many of the longtube headers out there. Not for the faint of heart.

That is what I've heard but my cars in for the winter so I figure an hour here and hour there. It will get done before spring.

Thanks for the input.

Can you explain a little more for my knowledge. I never understood the measurements for the headers. And what's makes kooks different other than being equal length header. Sorry if it sounds like a noob question.

Kooks is different on these cars because they're a mid length header vs the others which are true longtubes. The advantage to them are the o2 placements. These cars while not big in displacement love to breath especially in the upper rpm's so a 1 7/8 primary works well. Even N/A.

I went with Kooks 1-7/8 pipes. I'm planning to drop the K-member which should cut the install time in half.

Cool I think I'll go with the 1 7/8. I think I'll go with the x pipe I have one right now with the borla it sounds mean!! How much louder does your exhaust get with headers(with cats).

Hey man, it looks like in that picture you have 2 different midpipe extensions that connect to the headers, catted and O/R, are either one for sale?
