Learning Slowly...
Ordered an aftermarket 4" exhaust for mine and when I went under the truck to eyeball the oem exhaust I couldn't find a cat - where they not available on 01' Excursions? Just wonderin'
Manual transmission with 275 HP has a cat or had. Somebody stole mine
I think it has to do with the rare metals in cats - that or the resale value - the one on my a6 is like 2k from what I have understood...
