And when the mechanic who replaced the solenoids had to remove the headers, not a single bolt broke or needed to be tapped out.
Leading evidence: 'Replace solenoids had' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace roughly $100 and you�ll be happy' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I don�t really have any rust, except for what looks like a few parts that a mechanic replaced while doing work 2 years ago on my solenoid replacements.

They charged me $220 and used Galvanized 1.5 or 1.75� pipe, then spray paint heat treated it.

I used galvanized carriage bolts and nuts from Lowes for the sleeve clamps so they hold up better.

I don�t think the carriage bolts used on the sleeve clamp are stainless, though.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Is the stock exhaust system on a 996 fully stainless steel?
I don�t really have any rust, except for what looks like a few parts that a mechanic replaced while doing work 2 years ago on my solenoid replacements. One of the put an Audi exhaust clamp, and the other, who knows what brand it is - it�s rusted all over. I�d like to replace these clamps, as they are both visible from behind the car and it looks unsightly.
Anyone know of the stock Porsche clamps are stainless or have anti-corrosion materials applied to them (bolts included)?
VW/Audi part number 1ko 253 141 e
Unknown clamp brand
As you see the original clamps don�t rust (not sure if they�re stainless or just treated/coated). This is clearly not the case with the replacement (which I�m sure the mechanic made a hefty profit on). While the stock clamps are expensive, there are only two of them... replace both for roughly $100 and you�ll be happy when you look at the car from behind (everyone�s favorite view...😃
I read somewhere here on RL that most of the OEM bolts, nuts and washers on this car are also treated with a corrosion inhibitor. Nice. This is what separates the 911 from regular cars. I think a lot of folks don�t know this and use new bolts and pieces from other sources. This is also another reason why sometimes OEM is the way to go with Porsche.
I had to remove the mufflers on my car to get the Gundo/Fister hack completed, and I had zero issues taking apart the exhaust.
And when the mechanic who replaced the solenoids had to remove the headers, not a single bolt broke or needed to be tapped out. I�m sure having the better bolts in there made that more possible of an outcome.
I�m also thinking about what I might want to spend for a new exhaust system. I�d want full stainless and something that reduces the weight, but not willing to drop $6k on titanium or even $4k on something else.
I believe the tubing, mufflers, and sleeves are stainless. I don�t think the carriage bolts used on the sleeve clamp are stainless, though. Neither are the exhaust tip clamps.
I recently did a DIY Fister mod and replaced
the carriage bolts and tip clamps. I needed bolt extractors to remove both. I used galvanized carriage bolts and nuts from Lowes for the sleeve clamps so they hold up better.
I did. Believe it or not, I had mine done at SuperMAX Muffler & Brakes, 6230 W. North Avenue, Chicago, IL 60639. Phone is [phone removed]. They charged me $220 and used Galvanized 1.5 or 1.75� pipe, then spray paint heat treated it. I don�t think it was perfect, but it still sounds good 5 years later.
