Jake,- read and re- read your first line-
Then understand that no matter which c/c you go with, unless you have a dyno tuned butt, you will not likely be able to see a noticeable difference in the horsepower output of your engine, only that your engine will run better now that the pcm will have better data to work with.
The engineers at the factory didnt engineer these trucks this way because they had too many O2 sensors laying around, and they didnt stick them in the pipes by random chance- their location is fairly specific.
if in doubt, go back with stock exhaust system, that eliminates any possibilities that its an exhaust issue.

Bear is 100% correct. Fit is the critical factor here, not "this one flows 2% better than that one." All will flow sufficiently, and will remove the noxious gasses. Visit Magnaflow's web site, input your info, and it will spit out the correct item(s) If you still have questions, give them a call, accept their learned advice, install, and enjoy the benefits.

Read and re-read the last post- especially where it said “ give them a call...”
youre getting the best advice one can get under the circumstances- we are not your neighbor, or your mechanic, and we cant do it for you.
If you cant weld, cut, or fabricate what you need(or want)- then save your sheckles and pay to have it done by a muffler shop.

It's going to be different PER SHOP, let alone per state!
Do you not have a PHONE? CALL AROUND!
P.S. If you bothered to put a location in your profile, it's possible someone from your area could even recommend a good shop.

Hi 10thgen, all of the catalytic converters we offer are intended to be a direct replacement for stock, in other words, we do not advertise any increase in performance or power from using them. The correct cat for your truck will depend on the emissions standards that your truck needs to comply with. Unless you are located in California, you can use any of the units listed below to meet the EPA standards. Some will be a direct bolt-on installation and others are universal and will require welding.
-left side, direct fit - 23344
-right side, direct fit - 23345
-front left or right, universal - 99176HM
-rear left or right, universal - 99356HM
If there are any other questions that we can answer about finding the correct catalytic converter for your truck, please do not hesitate to call us at 1-800-990-0905!

Did you install a turbo or a supercharger? Did you build a stroker motor and drop it in? Did you somehow magically increase the airflow through your motor by 30+%? No? THEN YOU DON'T NEED TO WORRY ABOUT HAVING HIGH-FLOW CATALYTIC CONVERTERS! How many people have to tell you how many times that the factory converters (or factory-spec replacements) are more than adequate for the stock (or even mildly built) modular motors and factory-design exhaust systems in these trucks????
