Ok couldn't find this anywhere, I just picked up an AEM wideband for a really good price, I know it has to go after the turbo but how will this affect my readings running the cats? or should i just have them gutted and be done with it

 

i can only assume that you need the cats for emmissions purposes

 

not at the moment, my truck is exempt for another couple years

 

well then why not get rid of them until them and then when the time comes just weld soem hi-flows in

 

The cats wont affect the WB enough to make any different (at most, it's .1-.2 difference in AF) I ran mine with stock cats and WB after the turbo for 20k+ miles before i got a ORY.

 

As said above.Just make sure the wideband is after the turbo.I would gut the cats too.

 

People have been running widebands for years infront of the turbo on the GN's.....
