Crack in Exhaust Manifold...

not my cup of tea. I don't feel like dealing with the issues that come with aftermarket headers.
Wish the dealership staff would listen better to their customers feedback and not try to rush through stuff. They apparently let the car run for over an hour while they performed the airbag recall and then tried to listen for the noise at idle ... even though i specifically asked them to listen for it on a cold start.
We'll go through the exercise again today, with a cold start while i am listening on the phone since i'm not in town to do it in person. that should do it.

Have them pull off the exhaust manifold heatshield and look for staining on the underside from exhaust leaking from the manifold.

They started the car again with me on the phone this morning and the foreman and service advisor are insisting this is normal high pressure fuel pump noise. I told them to do just what you suggested. we'll see what they come back with. I'll be back home tonight and will go over there tomorrow. How are people so incompetent? anyone that's ever heard an exhaust leak should be able to easily tell this is an exhaust leak.

Just as a quick update for anyone who recently had this issue: we currently have a few of our CARB-legal replacements in stock (both sides) and can be ordered through any authorized Magnaflow dealer. You can find our local resellers by visiting our website here:
http://www.magnaflow.com/where-to-buy/local-dealers/
Believe it or not, the majority of our business is actually in catalytic converters! All Magnaflow cats are designed to be a direct replacement for the OE units. We do not claim any performance gains or increased flow from using them.
As far as the install, it will depend on the relationship you have with your local dealership. We have heard of dealerships installing our catbacks and other bolt-ons for customers before, but we imagine most will not feel comfortable with installing a non-OE cat, even with an EO number. We would recommend having them put on by one of our authorized installers in Socal, which can also be found by visiting the link above.
We appreciate that, Lobux. We make sure to play by all the rules so that we can offer a product to customers that is a hassle-free 100% street-legal replacement.
We appreciate your realistic approach. Catalytic converters are designed to last the life of the vehicle, so when we hear of one failing after a short period of time, there is usually an external cause that contributed to the failure. We do have a manufacturer warranty on all our products that covers them against any defects, but we do not cover failure resulting from aftermarket tunes, faulty ignition system components, etc. If you have one of our products and believe them to be defective, please contact our support team at 1-800-990-0905 so we can get some additional details. We are happy to take a closer look at them to determine the cause of the issue.

It is interesting that magnaflow already has a product that they've gone through the trouble of having carb tested. It doesn't looks like it's been produced for any significant gains over the stock manifold. If that's the case then the question is magnaflow obviously see's a market for these, so maybe this failure isn't as rare as we thought?

No. If it were that easy I might have considered staying. The entire assembly has to be functionally identical to the OEM part because the OEM part passed all the tests and the only way CARB will approve an aftermarket piece is if it is truly identical. I had an HKS SSQV in recirculate mode on my Supra and it would not pass smog. I put the broken OEM BOV in its place (the rubber inside had turned to glass and chipped off so it did not seal at all) and passed smog with flying colors. Stupid as stupid gets, but those are the rules. There is no way to get any aftermarket header with or without cats to legally pass smog in California.
I think it's awesome Magnaflow even bothered to develop and test these headers AND paid CARB the extortion money to get them approved. I have a whole new respect for them.

While the Magnaflow replacement might be enticing at first glance, do your homework on the quality of their cats. I had a Magnaflow replacement cat on my M3 several years back, and it failed within 2 years. I remember reading numerous reports all over the internet with similar outcomes.
Your tune has a lot to do with a cat's service life. The more rich the tune, the shorter the service life. There are a lot of reasons why the OEMS use fat tuning, but mostly because running rich won't cause warranty failures like running tight or running lean. And while it would be handy to be able to say their stuff has a high failure rate because it's posted on the 'Net, that's anecdotal evidence at best. Only Magnaflow know for sure what their failure rate it. Coming from BMW, I am sure you've seen the horror stories of bearing failures in BMWs, but I suspect if you queried 100 actual owners, you'd find the number of failures to be a whole lot smaller than the scary posts might make you believe. We have the same thing here with the valley plate leak (there's a thread on it), and it surely is an ugly failure, but no one here can say for sure if it's 1 in 10, 1 in 100, or 1 in 1000. We just know folks who have had the problem and once it's posted somewhere, Google lets others who have had a failure know there is a thread about it, so it becomes a lightning rod for complaints.
I make no claims for Magnaflow's quality, just concerned that making a blanket statement based on anecdotal evidence isn't fair to the manufacturer at all.

UPDATE:
Spoke to the dealership, they ended up doing the job by dropping the sub frame (i told them to do an online search for IS-F header installs before dropping the drive train out of the car). Pass side was cracked all the way around, driver's side had just started cracking. both sides were replaced and covered by the California Emissions Warranty. I'm happy with the result.

Ironic that it's in the same shot as the manifolds - I wonder if there's a slip in there that reads "to prevent choking, contact Sikky / PPE."

LOL that is ironic, I didn't notice that. The kit came with the car when I bought it .

That is quite the failure mode and seemingly always the rear flanges.
It **looks like** loading from hanging the exhaust system, coupled with poor design has that rear section pulling away from the block and the mounting flange is litterally shearing off the end of the rolled pipe. Is that correct?
Can someone take a close up of the flange and confirm the rolled pipe end is still inside the flange?
And why hasn't someone tacked the flange in place, pull the header and weld it 360°? Outside....
Just saying if you don't want to upgrade, are out of warranty, and if the cats are good, weld it up.

Crack in stock manifold = aftermarket headers!

Because only a few are failing under warranty, and those are being handled. The vast majority are out of warranty.

Unfortunately it sounds like you have a cracked manifold. Most likely passenger side. Be aware that these are very expensive parts and there is a lot of labor involved. Dealer will likely quote $4-5k for the repair. An indy can probably remove the manifold and weld it for a fraction of that if you're looking to save some money.
