Stainless Works exhaust fuel or rich smell

[rexford]

Hello, I installed the complete stainless works exhaust with long tube headers and cats and now the car smells rich or fuel smell from exhaust. I have an sct tune from 2 different companies to my specific car set up. I even had the 2nd o2 sensor shut off on both to see it that helped. What do I need to get rid of this?

Probably need to datalog and contact whomever you got the tune from.

When you change to LTs, you have to have your tuner change O2 sensor delay or your AFR readings will be off.
