ZL1 catalytic converters on an LS3
I know they are different part numbers and ZL1 cats are more $’s. Likely because of stainless steel exterior. Are they different inside and is it ok to use them on an LS3?

No issues with stock cats, cats came with ZL1 manifolds I bought. Thought I’d install them as well.

I think they would be better built because of the supercharger. But Im guessing of course.

I suspect so, installed them today. Seem fine.
Was an open day at the track so I gave it a try. Lots of corners but could open up on straight sections. Didn’t know 3rd is good to 100 mph. Maybe it’s the cats |

Then.....click the "Compute RPM" button. If you're running a 28" diameter tire, then it would be 5630 RPMs. http://www.advanced-ev.com/Calculators/TireSize/ KW

That Calculator is Assuming 1:1 Ratio in Transmission. With the SS Manual Trans 3rd gear 1.43 RPM would be approx. 8050 with 28" Diameter tire |
