Go to any auto parts store and get one for a S2000 should be like $10-15

 

why for a s2000?

 

because its 2.5 inch

 

got ya. thanks man.

 

I have a JDM 4-1 header with 2.5 collector and a 2.5 blox test pipe and I just went to autozone and i am using a s2000 donut gasket and its perfect

 

thanks for the info man! i got a ebay 4-1 header, with a ebay downpipe, testpipe and a apexi ws2 exhaust , just put it on today, but when i was putting it on, the donut gasket is all tore up n broken i got a loud exhaust leak.

 

Any further info on this setup? I have a b16 in my ek hatch and have (what I assume to be) an ebay 4-1 header, ordered a 2.5 blox adj. test pipe and 2.5 tsudo cat back exhaust. I have been searching hi and low for information on this exact issue as I have been wondering what donut gasket to use and how it paired with the ebay items. any further details would be greatly appreciated!!
