I am trying to cure an exhaust leak and am not sure what gasket I need. I am looking for the gasket that fits between the Y-pipe flange and center muffler flange. Do are DII's have a gasket that fits between these two flanges?

I check both A.B. and Rover's North and can't locate one. The first diagram below is from Rover's North but when I click on the the gasket I need it links me to the second image (Look at the last pic - bottom right - for the DII) - but then there is no gasket shown.

What gives?

 

No gasket there.

 

I didn't think so. I was cranking down on the bolts this evening and was wondering what was in there. How do I get these to two flanges to seal? I cranked the sh$t out of the two bolts, it's better than before, but it still leaks. It sounds like a wet fart when I'm accelerating up a hill. Any suggestions for me?
A diaper is not an option.

 

Unless the mating surfaces are damaged or you somehow aren't getting it to clamp properly, you are very likely looking in the wrong place for your exhaust leak.

Cheap test: get some exhaust wrap. Wrap the crap out of the joint. Take a test drive. If it still makes noise, you need to look elsewhere. If it doesn't make noise, you need to figure out how the mating surfaces are screwed up and bend them back, or go ghetto and slather it full of muffler weld, tighten it back up and hope for the best.

 

We're talking about that join right?

 

When the car is COLD - start it up, and run your hand over where you think the leak is - you'll feel it. (be quick though....)

I found several leaks at top of the y-pipes - the pipes had cracked just below the flange that attaches to the exhaust manifolds.

Yes, thats it.

 

I did. And I see water dripping between the flanges, which tells me that's where the leak is.
