After reading through how Trudeau and Biden are pushing a major Climate Change agenda together, it made me realize, maybe catalytic converters may not be a bad option. They do almost work like resonators, correct, even afternmarket ones? I was considering tiny 9" long stainless resonators instead of cats, price isn't much different. One big bonus to the Cats they have capped O2 sensor ports. I am planning either a AEM air/fuel meter at minimum or maybe and hopefully sequential multi port EFI on the new 350 stroker. My current 350, I have the APT part throttle set very lean and the idle mix will also get set on the leaner side. Full throttle on the richer side. I plan on clamping them on, expanding the pipes slightly as needed for a tight as fit as possible. Honestly less stinky exhaust would not hurt my feelings and like the catalytic converter exhaust smell much better. Here is the link.
