Coochas, can you please PM me on dealer? I'm in Boston area and have deposit on new GT3. Want to make sure I'm not with a bad dealer. Thanks.

Hey Rocky, the flow is actually the same because the path is The only difference really is the reduction of packing/sound-deadening and material for "muffling" if you will As we say you don't "gain" any power (or loose any) because ours is just for sound so we made sure to keep flow the same. Either way even with full on exhaust/headers etc... there's just no way that it could cause an RMS leak. Porsche's pretty much perfected that on their own with the M96 block and then now with the 997GT3 because of the crap seal they use (unlike on the 996GT3).

But, they DID deny his warranty claim.

Porsche is not dumb. They already have a claimed cause: "reduced backpressure" which I'm sure they can back up with whatever real or fictional engineering analysis/statistics they can cook up and that you will never have access to. I think it will take a lot more than the cost of an RMS replacement to prove that your engineering is right and their engineers/numbers are wrong. The best thing going for the OP is that leaks are common on cars without aftermarket exhaust.

(All above said in half-devil's advocate... not trying to beat on anyone but Porsche's weak-@$$ excuses.)

What this does say to me is Porsche is turning another page in its supreme arrogance and making customers take the shaft for their design deficiencies. What does this tell existing customers looking to upgrade? I think it says to stay with what you have until it's proven to work or go to another brand. I'm not the only one with at least the former concern.

As a counterpoint, we got some notice a year or two back on my wife's Lexus regarding a problem that could affect some % of vehicles. They would replace some part to help mitigate the problem and, further, extend the warranty on any related problem to 100K miles. I don't even remember what the problem was which is my point. Lexus went out of their way to stand behind their product.

Wow they're really pushing the boat out on this eh Any chance you can go to another dealership and start over? I mean the whole RMS thing has been covered to death on here and other forums and Porsche knows it's an issue on stock cars. Look at F4plt's issue for example;(

Good talking to you today and as we were saying Porsche is likely trying to put an end to replacing RMS seals all day long and wants us all to ignore it... Porsche (not the dealership) looses about $1200 a pop in order to pay for the RMS each time so I'm sure the crunch is starting to show since it's happening all the time. Also here's F4plt's

Why chance it ?

Sharkwerks exhaust costs $2k, doesnt provide any power increase and now is a warranty risk
Just not worth it

They will win.

This is the same short-term thinking that led to the downfall of Detroit automakers. When will manufacturers learn that you have to stand behind what you sell?

I forgot to mention this in my first post as to how to proceed from hear. I would request that the state the denial of the claim or the lack of warranty in writing, Not only that its void for the bypass but the How a bypass could cause the leak. Make them commit in writing so you have proof of what they are saying. Don't let them off the hook with verbal.

we all know plenty of 3's that have no bypass and have RMS, I was one of them I have the bypass now but it leaked 3000 miles before and can prove it was fixed and leaked again before bypass was put on.

Also, part two, you can play this game to. take the by pass off and bring it back when it leaks bypass off still leaks can't be pressure anymore. or \

Last point to make its not such a big deal on the bypass as they don't have a way to fix it but If I had other problems that they can fix I would not let this slide. That is what they are counting on. don't do it.

Not always.
Someone not me got rms fixed with bypass pipe recently. Entire gt3 engine replaced. Present ur case to a technically sophisticated service advisor who will work for u. If the car cannot deal with simple open
Pipe mod, I don't know...... I certainly won't be buying another 130,00 Porsche.

Thanks for that. I'm anxious to see what responses you get from your PCNA post!

seefouress

Thanks Alex. One clarification please. Are you saying that there is no reduction in back pressure with your bypass or that a back pressure reduction can't cause an RMS leak? If it's the former, then it would seem that the cause given by Porsche in denying the RMS warranty claim is clearly in error.

butzip

my 912 doesn't leak

Sorry I had to. That is total BS, this problem has been going on long enough now!! Can't they figure it out for F sake?!? Damn embarassing if you ask me.

sharkster

Hey Rocky, correct there's no significant change in back pressure with our system. There would be a change with something like side muffler deletes/headers cats etc... but even then for Porsche to deny it based on a straight pipe would still be a stretch. I mean if that were the case then all 996/997/boxster must be running straight through exhausts too and leaking

Guess some read the Source...then give you a call....

Most likely you spoke to the FTR involved, and if it is whom I believe it is, he is a stand-up guy that is a walking knowledgeable technical encyclopedia about the brand.

A good guy to have in your corner
