dimensions of the protege 5 downpipe O gasket?

[justin1194]

im looking for specific sizing/dimensions of the O ring donut gasket from the exhaust manifold towards the exhaust pipe before the second cat, im facing an exhaust leak with an aftermarket header.

It's a donut gasket, oem one will work. Autozone and autozone carries them. Do not get the cheap flat style gasket it's round and thick

If it fits on the secondary cat pipe tightly, you have the right size. The gap is between the donut gasket and the J-pipe. The exhaust springs may be worn out.
Other people have got a flex pipe welded to the secondary cat pipe and connect to the J-pipe with nuts and bolts and no springs. I think I need to do that.
