So I have been fighting exhaust leaks on the GMW for a while, and the biggest concerning one is the exhaust leaking into the cabin. I believe its coming in around the shifter surround.
I need to pull it apart yet, but due to the previous owner installing a T5 transmission, I am best guessing the OEM rubber boot around the shifter is long gone, and the actual surround has a broken tab as well. It really cuts down the enjoyment of driving this thing.
What is the go to for rubber sheeting for sealing in such an area? I do have a plan to *hopefully* fix the leak in the header (replacement after a bit more measurements to hopefully fit manifolds) but sealing the exhaust OUT of the cabin would be glorious as well.
Keeping the exhaust gas in the exhaust pipes is likely your best defense.
In reply to ross2004 :
That just might do it... I should check with some of the local drag racers if anyone is needing to update some expired gear...
In reply to John Welsh:
That is the overall goal, but the absurdity of how they fit the header in there, while impressive, is making taking measurements a bit difficult presently. I know its leaking at the flange as well as somewhere among the welds under the heat wrap on it. I need to pull the steering shaft as well as possibly pull the engine to facilitate the removal of the current header.

But then you don't get to hear those fancy colors after driving long distances.
While sealing the exhaust should be number 1, patching the hole is also useful. I buy rubber sheet from McMaster.
I sell rolls of rubber. Maybe a sample....
thickness? Width? Length?
sometimes I go to McMaster too.....
