I have a 99-00 honda civic ex and i just swapped in a b20...i got some OBX headers on there but there about an inch too short from my pipings...

can i use different headers soo i wont have to get my pipings re-done...cause i have a catback exhaust and i dont wanna do nothing to it..

Can some one help me ASAP!!!

 

pretty standard with swaps
take it to a shop and have them lengthen the pipes on the cat

 

How far are your header from the exhaust? Can you fit a cat?

If not go to a muffler shop and ask them to custom make you a test pipe so its still bolt on, and your catback wont be touched.

Downside is if your in cali, shops wont do it because of smog reasons and the fact that its illegal here. So you could also find someone with a header.

 

my headers are about an inch from my cat...i dunno what kinda car the headers came off of...i know is that its for a bseries...can i used 99-00 honda civic si headers without any modifications?

BTW: i have a high-flow cat!!

Welded or bolt on? Bolt on have them extend the end.

Make it work, or make it pretty. Pick one.

I would guess if the header you have on now doesn't fit than a 99-00 header would be too short as well. But you can try it. Like the other guy said, make it work or make it pretty. Besides, in a couple of months your cat is probably going to discolor and get some rust on it anyway. And no one will ever see your cat.

 

yeah just got get the extra inch welded onto it its easiest that way

 

If you dont want them to cut any of you piping then have them make you an extra pice, or make it yourself......take and cut a 2 1/2 piece of pipe and weld 2 flanges to it...then just put it in the gap and bolt it up....You may want to get the bolts that have the springs with them because if not you may cause the bolts to break...Goodluck

 

no u cant use a stock si header. all be series headers/exhaust manifolds are shorter than the d series.

 

had myne extended as well this will always be an issue with swaps unless your not changing series -
