P0171 due to exhaust leak


Recommended Posts

I did a little searching at on one side the code did pop up for the leak but before I go buying a new uppipe it's a leak in the up pipe/manifold area it's just a little hard to pinpoint.

 

 

Anyways does anyone know (if I need to get it) if this up pipe will fit?

the one I have has the EGT bung which I ended up just plugging with a bolt since it's not installed anymore.

It will fit. The only reason the Legacy GT is not listed on that compatibility list is because our cars have a catted up-pipe with a sensor there by default. I have the Invidia pipe with the bung installed on mine, it’s the same thing just $1 more it looks like.

I would recommend an up pipe with the flex joint in it (Grimmspeed, STi take off) as you'll have a lot less grief in the long run with fitment. The solid pipes have some fitment issues at the manifold to up pipe joint with leaking.

 

I’ve actually heard of a lot of problems with flex joints wearing easily but that could just be bad luck or due to the weather conditions people drive in. The Invidia pipe fit like a glove for me and my VF52. I would probably only recommend a flex joint if you are running a larger turbo or aftermarket headers but that’s just me.

 

I also wrapped my up pipe with DEI wrap and silicone spray and have had no problems after ~40k miles.

This my first was a flex joint seemed to rust from the inside out and fell apart when I took it off

I agree I like the solid Invidia up pipe, fit is great. I just replaced mine a month ago after 8 years.

 

I think you know to leave all the bolts loose until they are are started.

 

The impact gun and some Aero-Kroil the old bolt plug came right out.

Totes magotes. Can't go wrong with an STi. The Invidia is a POS.

Dude, that POS broke on you TWICE! You had it welded it back together the first time, remember? Why do you keep deluding yourself it's not garbage?

 

Invidia up-pipes leak. Invidia up-pipes break. Why do people keep buying them?

;) right I was typing that on my phone and then remembered the weld repair two years ago.

 

It does fit well.
