Exhaust header gasket - help needed

signes · 11-11-2012, 10:28 PM

In the midst of installing an Akra x-pipe and wound up discovering this when I removed the stock midpipe. Driver's side, completely shredded gasket.

Obviously wasn't expecting this so don't have a replacement. This is my daily so would rather finish tonight if possible. Anybody ever run into this or install the pipe without the gasket? (The one on the other side is totally fine.)

Appreciate any response tonight. Thanks (and thanks again to pbonsalb for all his help as I've been trying to work through this.)

I think I have the same problem and will be replacing it tomorrow. Any tips?

I replaced mine. They are inexpensive but were'nt in stock.

You may be able to cobble one using muffler tape for the time being....or multiple exhaust gaskets laid together. Maybe take the flange to an auto parts store to see what they have. They don't have to be torque very tight. GL -

That happened to me as well. Installing without he gasket will likely result in an exhaust leak. The dealer had them in stock but I found them at Napa (closer to me). Good Luck!
It's always frustrating when you think you have everything you need to complete a job but don't. It always seems to happen to me at 2AM

Nothing special as long as you have the replacement. They are a little snug when you slide them on but otherwise straightforward. Make sure any residue from the old gasket is removed first.

True!

Did you have to drop the whole exhaust or just loosen it to replace the gasket?

Any chance you have a NAPA part number? 2.5 inch conical exhaust gasket?

I don't see how you would have enough room to slide the exhaust back far enough to allow access to the headers without unbolting the midpipe. The pic below will give you an idea of how far you have to slide the exhaust back to be able to remove and slip on the new gasket.

Thanks, this is really helpful.

I replaced mine too at 80k km. It seems to be a common issue!

Found the source of the leak, the driver side exhaust header gasket as missing, passenger side was still in decent shape. Dealer must have forgotten to replace when they replaced the transmission.
