i was wondering for the descendent exhaust .....how would i do to connect the second o2 sensor that goes on the exhaust or does it not need .....

 

What second o2 sensor are you talking about? Can you post a pic? If not, is it on the piece with the resinator? (it's like a slightly larger cylinder that is welded in between the 2.5" exhaust)

 

The second o2 sensor is well before the portion of the exhaust that gets replaced. You won't need to touch any sensors when installing a cat-back exhaust on this car.

 

I had to plug the spot that was used for reading egt since my exhaust came off a boosted tc. That's why I was asking. All I used was a oil plug for a Volvo and locktite. Not sure if descendants came like that, or if that was custom for the turbo install. Either way I'm sure he figured it out by now lol
