99 Y-Pipe
Hey, Whats the deal with the 99 Y-Pipes? Instead of there just being 2 o2 sensors on the precats, there is a 3rd one in between them. On my new WSP Y-Pipe, there are only places for the 2, pre-cat, o2 sensors. Do I have the right Y-pipe or are there places for 3 o2 sensors on the 99 y-pipe?

Re: 99 Y-Pipe
If you have cali-spec 99, you need to reuse the OEM precat. One section should curve up and the other is just straight.
