Ive read lots of mixed reviews about having cats on a supercharged car. Seems like guys are experiencing meltdown of the cats when modifying supercharged engines. Can anyone relate to this? More specifically with ARH cats. I plan to do a mild build. Ported blower, pulley, 103 TB, and longtubes. Id really like to run cats for ease of inspection as well as exhaust fumes. Anyone doing it with similar mods?

Just finished my build with the same parts. Builder and I discussed the cats and thru both our research found no such specific info on ARH. I have heard of cats burning out from running to lean from the tune but I am far from an expert. Looking at my exhaust I am definitely not lean.

Thanks for sharing. How long have you been running with your current setup? Any track time?

Just finished days ago. I will not be tracking this car, strictly street and touring.

Congratulations on the build! I just saw your thread. I bet it’s a blast! Good luck.

Normal driving they will hold up fine. I’ve seen several sets from all of them fail on the dyno though. Really long pulls on street will get them also. The short blasts are fine but they won’t last in extended heat applications. Hopefully the bigger GESI converters will hold up better, but not a ton of info on them yet.
