The plug foulers is really making me think about gutting my cats. If it is that simple to get rid of the CEL. Now I just need to find a Y-Pipe.

 

what's wrong with your y ?? flex pipe ?

 

Cattman has a couple of extras.

 

Nah I was thinking of going with the Warp Speed Y Pipe.

 

I spoke with Brian last week and he mentioned the Y Pipes that where being completed. For the price of his Y-pipe alone I could go with the latest version of OBX headers.

 

I could be wrong but i don't think a y pipe by itself would create enough hp on the 5.5 to get me to buy one unless i got a set of headers but i can tell you that i love the sound and power gain from just having my cats gutted and you don't have to fuss with the sh!tty obx fitment issues that come along with the cheaper price tag..Id say Cattman or gut your cats to avoid future problems imo.

 

Since i gutted my cat maybe about 5,000 miles ago i haven't had any cel and im using anti fouler. They work great IMHO.

 

It's hard to make a logical argument for buying an aftermarket y-pipe on the 5.5 gen, unless you're adamant about retaining the precats un-gutted, and content to make a little extra HP for a pretty hefty cost.

And before you say, "But your car...", understand that I didn't arrive at my current configuration with benefit of hindsight.


So far so good. Great feedback, 036mtmax.

 

Not sure what I am gonna do now. I think I may just get the Non cattman Y pipe and gut my cats. Just gotta sell my stock system first. Oh and Rochester...Soon I will have a "Gunning for Rochester" thread. I was hitting my engine bay with degreaser and towels today till the heat made me dizzy. Once I break out the q tips and tooth brushes maybe I can have an engine shot as clean as yours!
Nothing but respect brother!

 

So you drilled the hole how big? 1/2"? Nice to see how it turns out! Forget adding wires if this solves all issues for a few bucks.

So I got to the precats but chickened out a bit going for the process since I had somewhere to go. Very happy I drive a FL car because all my bolts came off with ease. It's good to know I can put the heat shields back (they are in great condition). Put some anti-seize for the future.

 

Unless your OEM y-pipe needs to be replaced, just gut the precats. Replacing the y-pipe is not the most cost-effective power mod. That would be phenolic spacers.

If you do, I'll likely comment on your progress. Although I've been feeling somewhat jaded and impatient with the devolving nature of the 5th gen forum, so I'm not sure if that's an invitation or a warning.

 

Its an invitation for you to give some constructive criticism. Some of us are pretty **** on the exterior and interior but neglect under the hood. Make sure you reply with some HQ pics so I can compare!

 

Yea man 1/2 inch drill bit and drilled it out, thanks for that link too nish

 

Did you only use one of the non foulers? If you have a chance, I'd like to hear more details since this seems like the cheapest way to fix the CEL

Also, did you use the 18mm?

 

No they come 2 in a package in the HELP isle at auto zone, I think they were $4.99 They were the 18mm ones and there were a shorter set which looked almost identical but i went with the longer ones as i figured the further the 02 is away from the exhaust the better.. In the pic i posted you see one anti-fouler plugged in and above that where the other 02 is you put the other one in there, If you don't have an 02 sensor removal tool id have someone do it as it was kind of a pita to get too.Still no cel as of today.

 

Bumping this cause I've got teh rattle and I'm gonna have a shop gut my precats pretty soon.

Anybody got the part numbers on the foulers? Also, how's the CEL situation going for those running them > sims?

I wanna buy the foulers, drill them out and have them ready for the shop.

I think you need 4 of the 18mm ones. Two of them need to have a 1/2 inch hole drilled thru them I think. Also not sure what position the drilled ones go in. Further from the manifold?

 

Yup, need four 18mm's and the drilled ones go further from the manifold.

This only needs to be done for the primaries correct? Then the secondaries can simply be bolted back in?

 

This is to trick the secondaries NOT the primaries.

 

You only need two anti-foulers you can get them at Autozone in the help isle. There is a short 18mm and a long 18mm, Get the longer of the two. The guy i sold the car to still hasn't had a CEL and it's been almost 15k.

 

Correct. The primaries still need to source the pre-catalyst signal.

15,000 miles is quite a testimonial for this little trick.

Good feedback, 036mtmax.

 

I'm about to try this trick when I install my headers. I will post a review as time goes on. We may have figured a solid way around buying the rare 02 sims.

 

Had anti foulers since I gutted my pre cats about a year and a half ago. No cel since then.

 

Great news from people that have had the test of time go well. If anything, I think we could add length to the antifoulers if the code does pop up or even mess with the diameter of the hole allowing gasses into them.

 

That's why i tried the foulers first. Plus i didn't like the idea of splicing into my 02 wires even though if done right it has proven to be effective.

 

I completely agree. Cutting up the stainless sensor wires is just a pain in the *** to do correctly and the thought of cutting the harness itself is scary. Especially when voltage is an important factor in the ecu figuring values.

 

So you only need two of the long ones and they go into the manifolds right? No holes drilled in them. The othe two just go right into the original spots correct?

 

Im in the process of gutting my precats as well. Hopefully, we don't need to drill anything.

 

Here's a pic of one of the foulers plumbed into the Y after i installed them just to get an idea,
The only thing you will have to drill is the inside of the fouler 1/2 inch which takes like 30 seconds,
The link above that cjandura posted shows you how it should look.The other two you don't have to touch

 

Is it just the picture, or is that thing MASSIVE?

 

It's job is to pull the 02 further away from the exhaust stream so it's not sniffing as much fumes which in turn prevents the CEL from popping up, It sticks out about a 1/2 inch more than the regular 02 but who cares its under the car.

 

So, I gut the precats and if my catalytic converter is bad, would the foulers cancel the CEL without gutting the cconverter as well?

and i read from the link on the how to fouler,
"It is recommended to
only use this modification if you are using some type of fuel combustion
enhancer that will actually allow a slightly leaner mixture to fully
combust effectively such as various fuel additives like RXP or enhanced
spark plugs like the Pulstar Plugs, water fuel “hydrogen booster” add-ons
and other modification.", so this needs to be done as well?

 

Bad cat = bad cat. Bad cat = bad performance, cel or not.

 

If you gut the pre cats you don't have bad cats anymore because you are taking out all the crap inside and using foulers to trick the ECU, And your main cat isn't monitored by 02's so you can gut that or replace with a test pipe and you wont get a CEL.

 

It's fine dude don't worry about it, My car ran and still runs perfect. I always used 93 octane anyway because of timing advance but you don't need that crap.

 

And even then, you probably don't need 93. But stations that sell 91 are few and far between.





Let's see if that's enough bait to turn this into another "octane" thread.

 

What can be used besides a air chisel to gut?
and How?
Need to make sure, don't want to make things worse.

 

A huge-azz drill bit and a pair of safety goggles. But you'll still need the chisel.

 

So the foulers only go in the O2 sensors that are located in the y pipe correct? Only 2 of them. 1/2 inch does not need to be drilled in them?
