WBO2 sensor install question
 

Hi,
I am in the process of learning self-tuning for my evo x, and I know a WBO2 sensor is a must for tuning. My question is: with welding the sensor to the down pipe, it means that's a permanent install correct? If my plan is to have stock turbo and tbe swapped in 2011, I'd better wait until this is all complete then do the o2 sensor install?

Thanks.

The bungs are actually cheap so you could always get one welded in, then get a new one for the new exhaust, but you pay for the job to be done twice. Other options, if you plan on running a test pipe, just get one with O2 bungs in you can use on the new TBE.

Thanks for the info. I do intent to get a test pipe.
