Well ive got the classic signs..rotten egg smell, studdering badly at idle, loss of power, and a code. anyone know of cheaper cats? the only ones ive been able to find are 700$ plus. yikes.

Just buy some magnaflow high flow cats off ebay universal fit and weld them on in place of the stock 2 down from the manifolds. The other 2 that come right after the manifolds are harder to get cheap but im sure someone makes them too. Otherwise just buy some headers instead and run 2 cats or get someone to cut the first 2 out and run pipe in its place.

Idk if you've fixed them yet but you live in Wyoming so I would go no cats
