Ok so i have a b20b on my 98 integra, and if i was to buy either header or exhaust, which model cars do i buy it for; in example ls, or gsr. I have an ls by the way but i was wonder if it is the model of the car that affects the perfect fitment or the engine that affects the fitment.

Can i get answers from someone who knows for sure or has the same engine. Thanks..

 

You can buy an LS header, the GS-R one is different bc of the cat...

 

any more opinion?

 

b18b header

 

any more advices?

 

any b series header will line up with the head. However, it will not line up with the exhaust. Buy an LS header for your B20 and you will probably still have some difficulty getting an aftermarket exhaust which lines up properly. But, that's as close as your gonna get.

 

if i get an aftermarket ls header and an aftermarket exhaust this will bolts up perfectly to my oem cat? i heard that engine doesnt affect the fitment except if its an h or d series, but the chasis that affect the fitment.
