I am about to instal my Megan manifold and Megan 02. My question is should I use the supplied gaskets or should I purchase OEM gaskets? Anyone use the supplied gaskets, if so how did they work?

 

oem one... half of my megan gasket went off 3 days after i installed it!!!
i had to adjust it to my turbo as well to fit perfectly... but u should do that after you drive with it for a couple of weeks becouse after high temp it bends a little!

 

I would use the OEM gasket at the cyl head connection and the Megan gasket at the turbo hotside connection. This was necessary for me since the manifold's mating surface was not totally flat and leaked with an OEM gasket, the extra "squish" in the Megan one helped to seal it up.

 

OE gaskets for anything ahead of the downpipe...

 

does the OEM donut gasket fit a 3.0" o2 housing to downpipe?

 

use the factory gaskets

 

for the Invidia 3 inch O2 Housing, when the stock O2 is smaller?

 

+1 on using the OEM gaskets for O2 housing, hotside, mani.....

the ones supplied w/ the megan housing and mani are crap and will burn up and cause an exhaust leak

 

+2 on using OEM gaskets. I have the Megan manifold installed in my car, the supplied gasket that came with it didn't last 2 weeks. When I bought the car I immediately replaced the gasket with an OEM turbo housing gasket and everything has been great since.

 

Yesssir, def. use the OEM gasket, i helped install a Megan manifold on an evo 9 and not 2 days into driving it the gsket actually blewout, OEM is def gonna be the way to go, thicker and more reliable...

 

yes, the factory gasket between the turbo and 02 is open and only covers the outer edge. You should be able to re-use it unless you mangle it. The 3 inch 02 housing refers to the bottom portion where it mates to the downpipe... now I believe invidia my provide that donut gasket.

 

oem is the only way to go..

 

Thanks guys OEM it is.
