I tried searching but didn't find what I was looking for.

I got an AMS downpipe and Megan 02 housing, I was just curious if this setup required the OEM donut 02 gasket? (or another gasket?)...I just want to be sure

I heard of ppl reusing the OEM gasket, my 02 housing I bought used and it still has a gasket on it, curious if I could reuse it, although I wasen't sure if the gap I'm seeing between the 02 housing and dp flange is normal.




Your input would be great.
Just trying to get everything sorted for my virgin evo, I've had it for 3 yrs with only tuning it on stock setup...will go from unmodified to
-megan 02 housing
-3" TBE (AMS dp, Megan catback, extra borla 6" muffler@ the cat)
-AMS IC
-AMS LICP
-UICP (custom)
-3" intake w/ Amsoil filter (custom)
-spal slim fan
-walbro
Next I really need injectors but probably wait until spring

 

Someone can varify this

 

Looks fine to me, I also have a custom downpipe and MAP o2 housing and got the felpro donut gasket from advance (had to order) but fit like normal and was like 18 bucks I think. You won't need anything special, you can reuse it but if everything else is new might as well get a new donut

 

Thanks for the advice, everything is used pertaining to the gasket....I'll just replace it.
