i tried using the search engine and typed in "where do i need a gasket" but nothing helped me. i have a greddy evo cat back exhaust that i installed awhile back and i was just wondering if i need a gasket inbetween the header and cat. and if i need one from the cat to the exhaust pipe after it.

is there anything like a general rule of thumb for gaskets?

 

you can contact the exhaust company and buy an exhaust. i would'nt worry about it unless it starts leaking

 

You buy the flexible gasket from Honda.It looks like a tapperd washer. 10 buks from honda.

 

is that for inbetween the header and cat?[QUOTE=jdm_loser]You buy the flexible gasket from Honda.It looks like a tapperd washer.

 

Anywhere metal would be touching metal you need a gasket. Period.

 

yes, you need that gasket. they call it a donut gasket. you'll probably have to special order it since honda says "they never go out". just use the one that's on your oem header. if you don't it'll rattle and you'll have an exhaust leak.

 

yeah i think i have an exhaust leak. i need to get a new because i think when i put on my exhaust the gasket fell off and i never put it back on. thanks for the info guys
