Flange repair was too small, if anyone else decides to go this route, I recommend getting a slightly bigger size

Walker 31871
or any other flange repair kit that is about 2 1/4 inch
They run about 15 bucks for two from rockauto

Good luck to anyone who needs to do this, hopefully this helps at all

Thumbs up

Just replaced the original gasket on my 2007 hatchback with 120k miles and 10 salty upstate NY winters. :D

Before trying to loosen the flange bolts, I used a MAP-Pro torch ($50 at the Homeless Despot) to get the nuts red-hot. You can hit the nuts with a torch from the engine bay -- I unclipped a wiring harness to make more room to work. Watch your aim -- there are O2 sensor wires just above the flange on the driver's side.

After heating each nut, I crawled underneath, hammered a socket with long extension onto the rusty bolt head, and carefully(!) applied torque. Got them both loose with no fuss, and the rest of the job was easy. I used new bolts but kept the original captive nuts.

The replacement gasket I used was a Walker 31619. May be a little different than OEM gasket size (definitely different material), but it seems to make a good seal. Car sounds much quieter now and less rough when accelerating. I'm probably breathing cleaner cabin air too.

Time to do mine as well. I can taste the fumes with the hood open.. and a shot of SeaFoam shows it's leaking there, also be a good idea to take the header off and check that as well. Good info on the or replacements.

Yes, I would definitely monitor this in the future and for anyone else who owns this vehicle.

My spring bolts were just corroded to pieces which is why they snapped so quickly.

But yes, Definitely torch/Heat before torquing anything exhaust in the future!
