Cat confusion
My 2000 has a cloggged cat, what are the options out there ? Magnaflow recs 99509HM becuase of the engine size and test weight of vehicle but list is $ 394. They said a smaller cat would burn up. What is everyone out there running and has anybody burned one up ? I know DKF and Skipperw run smaller ones and MF has lots of ones rated for 6.2l and 6000 lbs. I would like to run the smallest quietest and cheapest one out there in front of a 5 x 11 x 22 #14578 MF muffler, Thanks

I can't really say. I put on a louder muffler and new piping at the same time as the cat. If you let the exhaust exit in the stock location I think you'll hardly notice a difference in sound between the stock cat and smaller cat.

If you're going to be towing a lot, or hauling heavy, I would go with the larger one so it doesn't get overstressed.
If it's a daily driver, and you just want to fix it right away cheap, and you're not going to be pulling heavy loads, I wouldn't worry about it too much.

I bought the MF 95509 cat it was rated for 7.5 liters and 13000 gvw and reccomended for the 6.8 liter and under $ 100. magnaflow reccomended their new 99509 Heavy Metal but it was like 50 bucks more, both have the same 4 tall x 7 wide by 15.5 body. I did not know the difference but figured it was probably just a new type of catlyst. Anybody have a clue what "heavy metal" woould refer to?

I'd put my fingure on a thicker gauge metal I.E more resistant to rust, metal fatigue.

And against Federal Law. Also not cheap when you fail emissions inspections, depending on the state your living in
