hey im putting headers on in a few days i was wondering if most people needed one two or three Foulers, and if you use more then one do you use both the moded and un moded Fouler and put then together and place that on top of the original one or do you only add another moded Fouler and make the chamber bigger?

for me , i bougth a pair of those antifouler. They come in 2.
I drilled a hole in one of them.
The O2 sensor goes into the drilled one,
Then the drilled antifouler goes into the undrill one.
The undrilled antifouler goes to s-pipe.

did one set take care of it? cause i have one set and its drilled already i just haven't installed it yet, if im going to need more i would wanna do it before i put the stuff on the car

GammaTNT 05-20-2008 11:02 PM

yes, i just used 1 set, i have a DC header by the way.
I have heard Megan header are sort of hit or miss.

CSOCSO 05-21-2008 12:19 AM

if u have megan header probably u will need 3 of those..

get two set anyway.. its cheeeeeap...

Thanks for the write-up wasn't sure if I needed to drill all the way through or just past the first part. A 1/2" bit looked too big to use but it worked perfectly. Thanks again!

just installed the DME header and antifouler into s-pipe ... and guess what, it doesn't work :tap: CEL still there ... sigh

CSOCSO 08-19-2008 12:21 AM

If you want a permanent fix go to a exhaust shop and get a o2 bung welded in behind the cat on the midpipe and relocate the o2 sensor and you won't ever have a cel from the aftermarket header.

Over a year and 25K no CEL.

I got the custom angled antifouler from InLikeFlint ....

Installed it same time as header and I haven't thrown cell yet .....

CSOCSO 08-20-2008 01:12 AM

i got 3 antifoulers and no cel since last year...

with two foulers the cel came back on the highway.

calvinhuh 08-26-2008 09:06 PM

for the people who is using more then 1 fouler

are u running stock exhaust.??

im running strup header.
it comes with 1 fouler.
when i installed it i had tanabe exahust on .


when i took off the tanabe and went back to stock

my CEL came back.
and seems like it wont go away.


aa by the wayy for the poeple using 2 or 3 anti foulers

did u guy have to erase the code after installign the foulers? to get rid of CEL?

or did the CEL just dissapear after installing it?
or did it dissapear after driving for couple miles??

CSOCSO 08-27-2008 03:49 AM

you always have to reset.......

calvinhuh 09-10-2008 03:49 PM

hmm is it normal that
after getting the cel
maybe like 1 or 2 days later the CEL dissapears
and then couple hundreds miles later the CEL comes back?

Mr_Meaty 09-11-2008 04:34 AM

i've heard of a few people with that issue...I think you need to add another antifouler on there...inconsistency...

aryan13 10-17-2008 04:06 PM

The trick to the antifouler is torun your car for about 15 minutes at idle. Don't rev the engine just let the computer get used to the new setup.

CSOCSO 10-17-2008 05:27 PM

it might come back on the highway.... if it does then you need a third antifouler...
