N63 downpipes no cel

Jay_d · 07-14-2021, 10:07 PM

Installed a set of VRSF downpipes about 2000km ago. Didn't want the trouble to install a JB4 so I use a 90 degree o2 mini cat from Amazon.

No cel after driving in city and high way. No pending codes either.

Very interesting, are all of your emission monitors showing ready too?

Jay_d · 07-17-2021, 12:52 AM

Just checked, monitors are all in the green.

nice!! how was the install, any tips?

Removing the oem cats is not fun. Remove the skid plate to get better access to the heatshield bolts.
Also I'm nearing 5000km's and catalyst efficiency popped up, the mini cat material is chipping away fast. I assume it can't handle the heat.

I would recommend finding a way to hide it all under the heat shield because during your emissions they will fail you if they do the visual check.

Before I had my tune I was failed due to visual, I had my heat shield on but not the engine cover. With the heat shield and engine cover it hides them much more and catch cans help out that much more to conceal it all. Just some advice for those about to go through emissions.
