No papers came in the box. I don't believe their website explains it either.

@xsl27x has the right idea if you've got a stage 2 tune from OFT or tuning with ecutek for something similiar it's best to remove the 90 degree bend for the O2 sensor bung, otherwise you'll skew values for the tune.

So what do you do with the o2 sensor

2 sensors go In the stock header. 2 bungs on the 1320 header. Just swap both over.

So forget the 90 degree fitting in just install the sensors as they are installed on the stock header is that right

Yes. If you're tuned via OFT or ecutek, you don't need to worry about CEL.

Yeah I wasn't concerned about a CEL I was going to have a tune, just trying to figure out what to do with the actual sensors

Pulled the stock header and sensors. Cleaned them up with some MAF cleaner and steel wool, light coat of anti-seize in the bungs and installed. Black in the collector, grey by the flex pipe.

Should be installed tomorrow, just need to source 2 nuts and bolts since the 1320 header doesn't have studs.

What overpipe are you using?

Got the header and overpipe in today. Just gotta find some bolts to mate them together since it doesn't have pressed in studs.

A few notes though:

I had to use the 90° fitting and extender due to space constraints. Without them, the 02 sensor was jammed against the plastic wheel well and I didn't want the sensor to get bent/damaged during normal driving when the engine shifts. I used red loctite on all the adapter joints so hopefully it doesn't rattle.

There is one header nut that is extremely inaccessible. All others can easily be torqued with an 8" extension + 14mm deep socket, no u-joint needed. To get this nut (driver side, under the runners) use a 14mm crows foot on the 8" extension. I hand tightened this as much as I could first, got all others to 22ft lbs, then came back with the crows foot.

I was able to get the OP in place even after torquing the header all the way down, without raising the engine. Just feed it up through the transmission tunnel and keep rotating towards the drivers side and it will slide into place. Just takes a little finesse and patience.

Here's a quick sound clip. I think I have a slight exhaust leak. Probably at the header/op flange.

Any rattles or anything so far? I really don't wanna spend 600+ on a header when I get OP and Header for less than 500
