I i have a garret 5 bolt flange housing and down pipe and i was told i dont need a gasket but i still think i do but the fact that i cannot find a part number for it is making me think not. So do i need one one and if so what is the part number? If i dont will it leak?

 

no you do not need to use one,ive never had one and i think most people on here dont use them either

 

ok cool thanks man

 

I use this one:

If your flanges are flat, then most people don't run a gasket, and usually the connection gets sealed by carbon from exhaust gases. My downpipe on my old setup leaked, so I got this gasket and it never leaked again. I've since been through several setups/downpipes, and I've reused the gasket each time. It's just some cheap insurance to me.

ATP also makes a similar gasket:

as long as your surfaces are true you wont need a gasket, to me its just something else that can blow out and cause more problems

 

both surfaces are true the face on the turbo housing was decked actually the kid told me

 

no, in fact i didnt even know 5bolt dp gaskets existed, Vband FTW!
