Question on cat back exhaust

[brandons95]

I was looking into getting the hks carbon ti cat back but I was wondering if the catback exhausts come with the o2 bung for the second o2 sensor. Thanks

I have the APEXi N1 cat back and it came with the o2 bung. Not sure if that helps much but I believe any bolt up cat back will come with the o2 bung.

Thanks, that is what i was looking for.

If it is "bolt-on" exhaust, it should come with a bung for the rear o2. My Apex'i N1 has one.

Do you know if the cat back systems will still bolt directly up if i have the cat eliminator down pipe.

It depends on what brand you are going with. I know the RRE dp's bolt up to the APEXi directly. But I am unsure as to the other ones.

Most items will bolt up to "stock locations." In other words, your cat elim pipe should end with a flange at exactly where your cat would be. So, in these cases, everything will bolt right up.
