i had dx headers wich have a single port downpipe. when i bought my swap they did not installed the headers cause they where 4-2-1 and the downpipe wasen't included. but i kept the header should i get a 2 port downpipe or keep my current setup? for now i have stock exhaust but a plan to install a cat back near future.

also can get the the header on the right it from a zc jdm sohc and left is d15b jdm

wich one you would choose?

 

pick the zc ....i believe it has bigger runners....if not, choose the d15b

 

but ur best bet would be a 4-1 header....check out bisimoto....looks nice and pulls some power out, but a lil pricey

 

i am not interested in a aftm header. 4-1 don't think it a good idea for a stock motor.

 

bump

 

where'd you get the downpipe for the jdm d15b?

Thats a very uneducated assumption. ANY motor benefits greatly from a good exhasut menifold setup.

 

If you have to choose from those, I'd say ZC one.

Yes, a header (tubular exhaust manifold) flows much better and opposes less restriction which means more power. Even if the motor is stock.
