What is the gasket called where the exhaust manifold meets the first O2 sensor right off the motor as it turns down to go under the truck to the cat?

Thanks

 

Collector?

 

I just replaced mine last night, what a difference! Totally different truck! They are called collector gaskets. I got them for like $5 a piece. You need two. They are really easy to replace too.

 

Tramendous....Thanks

 

where did you buy it?

 

Oreilly's

 

Exhaust manifold to downpipe gasket? Should be able to get them at autozone, checker, napa, online, muffler shop, etc.

 

I bought mine last week as Schucks and still have an exhaust leak at the collector not sure what to do now. I have and extra manifold might swap them out to see if the old has a warped flange.

 

i think mine is warped like yours as well.

i replaced my blown out fel pro with ones from napa, then replaced them with oem toyota metal ones, and still an annoying ass exhaust leak

saving up for a header and new cat/muffler.
