looks like my 02 sensors are done for...

is this the type of deal where i might as well just install a whole new turbo back system with new 02 sensors ?

how hard is it to replace them alone ?

also if you are on a budget, what would be the first/cheapest thing to do to get more flow thru your exhaust ?

thanks

Primaries or secondaries?

Both !

Well O2s arent hard to replace at all. The primaries are the only ones Id worry about replacing since theyre the only ones that actually do anything. You could just leave bad secondaries and deal with the CEL or get a spacer for them. As for the exhaust, I dont see any need to get a whole new exhaust if theres nothing wrong with the one you have right now. Just do the primaries and youll be good

Cheapest way to get more way is to gut the pre cats on the stock exhaust. You will have a cel. Look into spacers or tune out the cats and post o2 sensors.
