Non-Fouler Attempt

[Jinx]

Ok, I caved in after PMs and countless people on here recommending a catless mid-pipe on a FI car. I'm running the stock Whipple tune and I have NC inspections to deal with. Hypothetically, I'm planning on using two stacked non-foulers like people have mentioned. But through searches on these forums and others, I can't find anyone with FI on a S197 using non-foulers. The Whipple tune is fat from my understanding, so I planned on using a idea I found on the SRT forums using steel wool (fine grain) packed into the lower nonfouler (the one that isn't drilled out for the O2 sensor).

I guess I hailing people with FI using these things and to see if the steel wool is necessary. I rather not have it due to having less things go wrong. South Carolina is starting to look like a better place to live.

Off-road H-pipe will be installed Monday.

Why not try getting it inspected before you install the O/R H pipe? I went through hell trying to get the Hot Rods and Kooks with catted X pipe to pass inspection. I kept failing due to the rear O2s not being ready. Went back and forth with my tuner even getting an emissions tune with no luck. I eventually gave up and went outlaw until I installed the Whipple. Got it from Lethal with the custom Jon Lund tune. Believe it or not, I passed with this setup, Whipple, Hot Rods, and Kooks with a catted x-pipe.

i dont have the stock mid-pipe. and the shitty upr catted x-pipe has the "rear" o2 bung pre-cat so i t redundant in my case.

A friend here eventually got it done with two sets of non-foulers on a KB car with LTs.

What year is your car? Some 05-06 cars get through with the rears turned on, but without throwing a code.

Edit: Nevermind, saw it in the sig. You may want to just give the OR mid a try, leave the O2s in and on, and see if it throws a code.

Well I have to have them on to pass in NC. So I hope this works.

Edit: I see that you understand my position (NC). lol.

I have no cats and running a pypes o/r h. Stacked 2 non foulers on both of my rear O2's, loaded my shitty diablosport vortech tune since it's a 50state carb legal tune. Of course my car ran like crap but I stayed out of boost and never went up 3500rpms while doing the obd drive cycle, worst 2 days of my life. Got all emission monitors ready! no cels and took it to my buddy's PIF. Told him to just close his eyes and do not do a visual under the car just plug in the machine and it passed!off the hook for 2 years.

Sounds good. I'll try the traditional no wool method first. lol. Thank you for sharing.

I'm getting nervous about my MD inspection coming up this year. I got the 02 foulers stacked two high at the moment and It through a sensor code the other day after putting 300 miles on it with the new setup. I'll clear the code and see if it pops up again... but I really hope that I don't have to jump through hoops in the end to get this thing to pass.

H-pipe installed with double stacked non-foulers and over 10 miles and no code.....we will see how far this goes this week.

I didn't think that MD checked if the rear O2s are turned on as of now.

what do you mean both rear 02s? i have three on my midpipe. two in that cats and one after

 

[Jinx]

One O2 is the primary reading, the other two are the "rear" or "downstream" O2 sensors.

 

[irishpwr46]

which ones?

 

[Jinx]

On the passanger side the one closest to the manifold is the primary. the other two are considered the rear O2s

After I have hacked, reset and done the drive cycle...I use this to verify that it will pass:
