1320 Header & Overpipe
 

Is anyone using this combination? I've found a couple of posts on the header but not the overpipe. These are definitely on low end of the price spectrum, are they worth it?

On a slightly different topic, any concerns of not having a heat shield with the aftermarket headers?

Everyone I've seen use these have had exhaust leak issues and strange rattles. Rattle has been narrowed down to the "CEL Delete" that they weld on... that also does not work.

I'd avoid personally.

I just ordered this combo, will be here Wednesday. I read it was mostly the header not playing well with other overpipes but I grabbed some grimmspeed gaskets just to be sure. I'll try to update once it comes in. I have my doubts too...

Yes, i've UEL & Overpipe !

No leaks and no CEL in my case,
I replace gaskets using original subaru parts

Here you go boys, showed up today while i was installing my Perrin intake. Let me know if you want any other pictures. The shipping weight said 22lbs for header/op/hardware. I'll be using grimmspeed gaskets instead of the one provided and I plan on removing the 02 L-extender they provide since I'll run an OFT tune. I probably won't be able to install until next weekend, the 22nd.

Why o2 spacer rattles?

Probably because its really 3 separate pieces.https://uploads.tapatalk-cdn.com/201...edee746c5b.jpg

And what to do for free rattle?

Either remove it and screw in 02 sensor like on the stock header, but you'll need a tune to turn off the CEL. Or keep it and use a good amount of loctite should work, but I'm not sure how it will hold up to high heat.

I got my header and overpipe in last week. I'll be installing this Saturday the 16th. I'll let you know how it goes.

The 90 degree fitting provided with the header is that where your o2 sensor is supposed to be mounted instead of directly into the header

Sent from my SM-G900V using Tapatalk

Yes, there's also a second bung further down the header that doesn't have the 90° bracket. I understand it's entire purpose is to eliminate a CEL, which only uses the first sensor to decide if a code should be thrown.

Does 1320 provide any instructions about the o2 sensors

Sent from my SM-G900V using Tapatalk

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

Sent from my SM-G900V using Tapatalk

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

Sent from my SM-G900V using Tapatalk

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

Sent from my LG-D800 using Tapatalk

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?

Sent from my SM-G900V using Tapatalk

1320 54mm to stock front pipe

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

Recently just installed mines and they do have a rattle coming from what I think is the flex pipes. I definitely feel the difference in power and I had only purchased mine for 275 so I would say worth.

i have the 1320 headers and overpipe. 400 miles and got a cel but i cant tell if its the O2 or the flex threads broke causing a code. i habe the 1320 headers and OP but i also have the full Invidia N1 system so who knows. hope its a simple fix...just hope the headers aint break....

you will get the CEL if you aren't running a stage 2 tune that disables the O2 sensor CEL. O2 spacers don't always work for everyone, if you are running one at all.

yea i get u and not running anything other than what the box brung however i will be getting a tune this spring. with all the bolt ons and E85 should be looking up to 215-220 whp
