No honda dealer stock 2.5 donut gasket for my hytech header. Im having hell time finding 2.5 inch donut gasket in stock. anyone have part numbers from local stores??any make model??

 

TTT

 

Felpro 2 17/32" Header Collector Doughnut Gasket Part Number: 9587

 

is that 2.5

 

It is 1/32" over 2.5" that's so it can slide over the 2.5" header pipe.

 

I had a similar issue, and ended up just going to NAPA and having the guy help me find a donut that would fit- the autozone guy kept bringing out exhaust manifold gaskets (he wasnt sure what a donut gasket was)-- I ended up using a felpro one off a GM

 

you got'er the felpro number that I posted above is actually for a 78' Z28 Camaro
