will a dc-sports header bolt right in to a b16 or is it longer or shorter?

 

It should... but what chasis is the engine in and what dc header are you using.... gotta be more specific dude

 

haha, sorry, i wasnt thinking...its for a b18, and i wanna put it on my b16...i know it will bolt on to the motor, but will it be any shorter or longer on the other end?

 

it will hang lower (as in less ground clearance) because the b18 block is taller.

 

What's the design? 4-2-1 or 4-1?

 

its a 4-1

 

my jdm 4-1 header (like the jdm itr) is the same length. just hangs a little low. and you need a 2.5" cat.

 

cool, thanks guys

 

What car do you have? Integra gsr header are shorter. B16/Type R are same length. Not sure about ls.

 

i have a 99 civic si

 

Realistically you would want the 4-2-1 design to 'save' the TQ which would be lost by the 4-1 design. However, the gains are MUCH (overall) with the 4-1 design in my opinion, at high RPM's you will feel the increased power. Again, the dyno screenshots are very informative.

Don't for get the torque the header down evenly on the gasket!
