Ok so I am looking at some cheap headers for my Integra RS (B18A1), and I found a few that look suitable, however they only have 2" diameter @ the collector.

•Is that a good size?
•What diameter is the stock one?
•Would bigger be better? If so what size should I shoot for? (I understand this question cannot be answered without knowledge of the planned modifications, I do not plan to turbo, but I may do cams and valvetrain down the road, mild to advanced modifcations geared toward all motor setup is what I am planning)

So the setup would look something like 2" @ collector, 2.25" at cat (Header end) and 2.5" (At exhaust end), and 2.5" exhaust as they sell in the package. Is that good for what I plan? Or should I try and go 2.5" all the way from the collector back?

Thanks

 

Anyone?

 

2" is good enough. 2.5" if you do extreme all motor work.

 

That's a lot of talk about things coming from a girl?
did you see my sig??

anyways, what type of brands are you looking into?
Mild setup that would probably be fine, with headers such as dc sports, or others of the same price range.


Oh and if you want to see the type of headers Way up in the price range, & droolable.

Oh, and I noticed you said 2.5 exhaust, since you're not going to be doing immense n/a work, you can prolly get away with 2.25
