Replacing exhaust

Good luck, I'll certainly be paying someone else to do this... :sad:

So what would be the electrolyte?
Click to expand...

You are quite right, that without an electrolyte, there is no galvanic corrosion, but as Alex points out, it is bad engineering practice to use a combination of metals with the potential for this type of reaction. If the car is not routinely used, moisture could condense in / near the threaded areas. Heat is also needed for a galvanic reaction, but in this case it is your friend as the high temps would evaporate any potential electrolyte. I can't see how Ti has any benefit over SS in this application. I recall this matter was discussed at reasonable length about 9 months ago.
 
Slow progress, another tight spot where normal drill won't get in

Passenger side complete, 8 studs drilled and chased out with the tap supplied in the kit

Very happy, just the 2 to do in the drivers side and it will be finished

Drivers side, what's left of the studs cleaned up with an 8mm die, gold thumbscrew needs a large washer added as it doesnt fit fit flush with the head and won't keep the jig tight to the head if it's not fitted
 
Finished all 12 holes ready for SS bolts :thumb:

Thanks Ian, I just need to sort out the oil leak from the plug tubes easy whilst the exhaust and bumper are off and then next week when the new parts arrive i'll Put it together, might even have time for some DIY that I promised the wife I would do whilst on holiday
 
I thought (most probably wrong) that SS studs on an alu head was a bad idea due to galvanic corrosion, negating the SS advantage over standard studs/bolts. Doesn't someone on here produce affordable (as much as they can be) titanium versions?
 
Have you not read the previous comments in this thread. Titanium is worse than Stainless with regards to attacking Aluminium.
 
Hands-up. I didn't read the whole thread. 17 years on the forum and 42 posts for a reason :)

SS is still better than standard ones then?
 
Yes deffo. My SS ones have been in for other 4 years and wound out easy as anything last month.
 
The bolts corrode where they go through the exhaust manifold an gasket, on the Porsche OEM manifold it's a mild steel and stainless sandwich which itself corrodes around the mounting holes and makes the bolts rust just under the head, hence why the steel ones shear off.

The other issue is the bolt heads disappear over time so you round them off when you put a socket.

The only advantage is that steel is easier to drill out than stainless or titanium
