Proposition 65 requires California to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. This list, which must be updated at least once a year, has grown to include approximately 900 chemicals since it was first published in 1987.

I watched a ton of videos and finally found one from Edge Autosport that went through 6 different variations of ETS setups.

In layman’s terms, a catback exhaust system provides a smoother, more streamlined path for exhaust gases to exit your car, allowing your engine to work more efficiently. When catalytic converters were first introduced, most vehicles used carburetors that provided a relatively rich air-fuel ratio. Oxygen (O2) levels in the exhaust stream were therefore generally insufficient for the catalytic reaction to occur efficiently.

Considering cat-back exhausts replace more restrictions, they typically offer increased performance and noise compared to axle-back systems
