Hi flow cats

[ViperPete]

hey guys

I have B&B longtubes with high flow cats.

The stuff inside the cats is breaking apart and rattling like hell.

If I cut them out and weld in straight pipe am I going to have a CEL?

Thanks

If you don't have a tune that has turned off the rear O2 sensors, you will.

Will the CEL cause the truck to run badly?

No.....it won't turn into a Ford!

Problems with the front sensors is a different story.

You can buy spacers off ebay for like 15 bucks to space out your rear o2 sensors and that way they wont throw a code

I had them turned off when my computer was flash tuned. Never had a problem running the JMB mid pipes. All 4 O2 sensors were in the pipes just like stock.
