How are y'all doing that..catless
I'm new to performance and computer controlled engines, btw I have a 99 5.3 Sliverado. How are you guys supplementing the signal from the o2 sensors so that you can run catless?

That can be taken care of with a performance tune. The tuner can adjust for any new conditions that are caused by exhaust changes. I know Blackbear Performance can do it. I believe Wheatley and Nelson can too.

10-4 on just have it tuned out. You put you a nice exhaust and a catless Y and get you a good custom tune from a reputable tuner...and you'll enjoy your truck a whole lot more.

02 sims are not being sold new anymore and they were illegal in many states therefore you couldn't pass visual inspection. A tune will be way more beneficial and get the most out of running the new headers and catless y pipe!
