Where is the best place to buy an intermediate exhaust pipe? (manifold to wastegate)

Vroom · 10-31-2002, 07:52 AM

The droaning noise I'm getting on my '86 944 Turbo is apparently coming from the intermediate pipe between the exhaust manifold and wastegate. This is supposed to be a common problem with these systems (double walled pipes?). Where can I buy this part at the best price? The parts mgr. at the dealer says that the replacement pipes are designed to avoid this problem in the future. But his cost is: $1158 just for the part.

My mechanic is checking around.

I have the "breakout" schematic of the exhaust system. The part number is;
#951 111 096 15 I believe.

HAS ANYONE ELSE EXPERIENCED THIS PROBLEM? (Droaning noise after car reaches operating temperature, doesn't matter whether it's in or out of gear)

Thanks very much.

Hi,

The exhaust piece that you are talking about is also called a crossover pipe. It connects the exhaust manifolds, the wastegate, and the turbo together. I would check on ebay as I see these come up sometimes. Also check with some auto wreckers like PAP or 944 Ecology. Although this part does have double walls, I have not seen one fail, but that does not mean much. I did have a double wall exhaust pipe collapse, but on my car it was the pipe leading into the catalytic converter. It collapsed so much that it choked my engine to the point that it would barely idle.

Got an 86' turbo. Took it to my garage to investigate what I thought was a crack in the manifold. Turned out to be a 3" crack in the cross-over pipe!. I had resigned myself to a large bill but the mechanic said that it could be welded. These guys are specialists and assured me that some specialist welding would fix it permenantly. Gave them the benefit of the doubt. The welding cost £40.00 ($65.00) This was great! Unfortunatly the removal and refitting including 'O' rings and new studs to the wastegate cost just under £300 ($425.00) Just got it back and the exhaust sounds sweet with no problems.

Check to see if yours pipe can be welded...
