hey i was wondering how easy it would be if i tried to install an o2 sensor and exhaust by myself. I dont know how yet but im going to learn. Would this take awhile?

 

I have limited mechanical skills but I installed the AWE Twin 2 exhaustmyself. It took me a little less than 4 hours. I used jack stands and it was freakin cold out, so that slowed me down. It was really pretty self explanatory.

 

4hrs for a cat back? That is a long time.

Anyway, changing a O2 is really easy. Getting to it is the PITA. If it's the drivers side primary, it's tucked in there, the passenger side is a little easier.

You will need a crow foot wrench to get at it. Really it takes about 15min, but it may take over an hour to figure out how to get a grip on it & break it loose.
