I will soon be removing my a4ld for rebuilding. I want to remove the y pipe to make it easier. I don't think the pipe has ever been removed. I think I'll end up in a 15 round fight to get it out. I already think I'll have to cut the fasteners and drill them out but it looks awfully tight up in there and I doubt I'll be able to get a hot wrench in there either. What has been your experience in getting the y pipe out?

Cut or snap off bolts and clamp if totally rotted....


Otherwise full manifold replacement with bad ass stainless fasteners

Sometimes the bolts come out with an impact... Often they do not and break off. Then you have to drill out what's left and chase the threads or use a nut... Chasing threads under a car is about the least fun thing I've done, nut is my preference.

I didn't ask for your life story, just answer the question!
Take it to an exhaust shop, pay them to remove the Y-pipe and replace all the hardware...
Now go home and easily remove your Y-pipe with no issues.

When I replaced my engine a few years ago I used a reciprocating saw to cut the Y-pipe so I could get it out with the exhaust manifolds still attached. Once out, I was able to deal with everything a lot easier. Then I had a muffler shop weld it back together. One piece of advice if you go that route: mark your Y-pipe before you cut it so that it can be re-aligned exactly as it was before cutting. I didnt' do that, we had to eyeball its alignment, and ended up needing to re-cut, re-orient and re-weld it.
