Will a USDM Type R header fit a JDM b16 in an 90 integra? or will i need a longer/shorter cat? or some modification?

thanks
need to know asap thanks

 

i think it should fit.

 

It'll fit the block, but I think the cat won't reach all the way.. also I think the flanges won't line up.

 

flange angle is most likly different than your factory cat..

 

damn, does anyone know for sure so i don't waste my time putting it in and taking it out?

THanks for alll the help

 

i heard that all bseries headers fit the block but when you go to bolt up the end of the header to the cat you have problems. i have a Kamakazie for an ITR on my GSR and I had to get about 2 inches taken out of my exhaust and the fittment of the entire exhaust system is still kinda out of whack.

 

ok thanks alot i have a high flow cat for a eg also so maybe it'll just work out that it'll fit with that i guess i'll go for it

thanks
