Which header for Beta swap?

Hey guys, I'm considering the beta swap. Which header seems to have the best fitment with the Accent? This would probably be a 98 or 99 Accent with a 2000 or earlier Beta engine. Thanks!

I own a OBX 4-2-1 header on my beta swap accent that worked out ok. Got it off of ebay.
How do you like the gains? Did you put it on during the swap or after? I would probably do everything at once...

Anybody dyno 4-2-1 vs. 4-1 headers?

I'm a newbie to Accents but I have swapped a Chrysler 2.4 into my Neon and have had loads of fun. I'd kinda like to do an Accent as a "mini me" 14 second 1/4 mile, 30mpg daily driver :)
The gains are awesome with all the extra air flow/gas. I have also added a s-afcII to control all the air/fuel.
I have an ss autochrome header off of ebay, quality was good, shipping was super fast, fitment was ok, 200 bucks to my door in canada, came with header with both 02 bungs, downpipe, catdelete pipe, and all hardware and gaskets....whichever one you choose make sure it has the upper o2 bung cause otherwise it'll be a pain in the arse. I dynoed my beta with just intake, header, 2.5 in exhaust, and i made 133 whp.

did you get a cel because of no cat ??? is 2.5 the best size for a na beta motor??
Yes I have a cel for no cat...but if you put a cat in, it shouldn't be a problem. you can buy 2.5 hi-flow cats for very cheap. The cat delete pipe that it comes with is seperate so if you want to run your cat it is no problem.

In my opinion for a mildly tuned n/a 2l 2.5 in. pipe is more then adequate. I dont think you'll see any gains with a larger dameter pipe
