ok so i have a ek hatch, my ws2 bolts directly onto my header,no cat, and i was wondering if a 2.5 inch header would bolt onto the 2.25 inch piping. im confused because i was under the impression that i would need a 2.5 to 2.25in testr pipe but the mid pipe on the ws2 is long so yeah and advide would be greatly appreciated.
thanks

 

bump no one??

 

It should bolt up no problem, but I thought the WS2 exhaust was something like 2.4 inches or close too it?

 

no i think its 2.36in

 

its 2.25 on the inside and 2.36 on the outside of the piping.
i have my stock header on it now but are most aftermarket headers the same length?

 

1999 civic ek b16-needs new head4ers!!!



Header, You only have one.

 

yeah...thanks
