Catalytic converters

[Skyboogie87]

I just put a mbrp pro series cat back and jba shorty headers on my 2019 1500 custom v6 4.3 but would really love to finish the job and Replace the catalytic converters with more high performance but can’t seem to find them? Does anyone know of any or what else I can do

Modern cats are pretty high flow. Not much to be gained any more.

You may have to build your own, it would be cheaper than a brand name when you find one. 
 

100 cell or 200 cell converters would be your best bet. 200 is about average for aftermarket high flow cats pipes. 
 

400 cell is the most common factory converter. 
 

You will gain more sound than noticeable power.

Not worth it. No power to be gained.
