Does anyone here use O2 spacers in combination with bypass-pipes (without a tune)? If so, does it prevent the CEL from coming on?

I have a FVD muffler that I would want to use with bypass pipes but I don't want to flash the car just yet.

 

Wondering if
works...

 

Hi Guys,
Hah speaking of Amazon!!! Vibrant 11619 Use the smallest insert. Has worked for us

 

You mean those?:



Do i need 4 of them or just 2 in back?

Thanks

 

That's it, with small insert. Only 2 on the rear or secondary sensors.

 

Awesome! Thanks!

 

Is it normal when cel comes and go?

 

Will these work on the 2016 GT3 RS? I am installing a full Akrapovic system (no side mufflers)

 

Hey guys Scott here at Fabspeed Motorsport, we carry the top of the line O2 spacers with 20 Catalytic Cells that minimize the risk of pesky check engine lights.
Universal O2 Spacers with Catalytic Converters scrub the exhaust and lengthen the distance between the O2 sensor(s) and the exhaust flow to reduce the chance of a CEL.

We've taken our O2 spacers a step further. The factory ECU compares the readings from a pair of oxygen sensors to measure the effectiveness of the catalysts. When a high-flow cat or catbypass pipe is used the exhaust gases reach the O2 sensor faster and uncleaned, leading to high chances to throw a CEL. Our O2 spacers retract the secondary oxygen sensors from the direct flow of gases, restoring the balance that the ECU requires when using aftermarket catalysts or catbypass pipes. The high quality built in catalysts scrub the exhaust to further reduce the chance of a CEL. Two fitting options and the two piece design allow for adjustment to get best possible fitment and results.







FEATURES:

• Fits most makes & models worldwide (Sold as a Pair)
• Compatible with all Fabspeed Motorsport header, Sport Cat, and Catbypass products
• Minimizes the triggering of the CEL by moving the O2 sensor further from the exhaust stream and scrubbing exhaust
• Male end threads into existing M18 x 1.5 O2 Bungs
• Spacer body dimensions: 3 3/4" L x 1 1/2" W x 1 1/2" H
• Fitting dimensions: 1" L x 1" W x 1" H (not including threaded portion)
• 1" depth of threads on fittings for adjustments

IMPORTANT NOTES:

• For use on downstream oxygen sensors only
• This product cannot guarantee emissions compliance and resolve check engine lights
• Universal fitment

Still don't know if the Vibrant or Fabspeed O2 spacer will work on a full Akrapovic exhaust --> http://www.akrapovic.com/en/car/prod...60&yearId=4247

Would really help so I know what to order....

 

I can speak for the Fabspeed Product, ours fits most makes & models worldwide, and the male end threads into existing M18 x 1.5 O2 Bungs (standard size)

 

Do you still make these? Can't find them on the site.

 

Likely pulled due to legality issues.

for me since the installation of the esmotors line without cat and extensions 2 months ago the engine fault has appeared 3 times. Error code P2099
