o2 sensor replacement question

Recommended Posts

I am hoping someone on LP can help me. I am trying to figure out if installed cat bypass pipes need to be totally removed to access the secondary o2 sensors on an SV-R (in order to put o2 extenders in place)? It seems like a TON of work just to access sensors that may occasionally need to be addressed by the dealer. Or can you get to them with from the top of the engine without removing the wing, bumper, etc.

 

Any help is much appreciated!

Pretty sure you need to remove everything to get access to the testpipes/cats. Also I would not recommend the extenders. They don't do anything. I've tried them on my Porsche Turbo, Gallardo, 458, 488 and it doesn't work. Aventadors don't throw a cel with test pipes anyways. If it does, you are better off getting a tune.
