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.

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.

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?

It's OK to have a floating flange, but it's not OK to have an exhaust leak. If these exhausts were not leaking, Lexus would not be replacing them under warranty, they'd be telling is it is working as designed and call it a day.

Well, unfortunately, no one has the direct-swap Magnaflow in stock as "it's a built to order" and Magnaflow doesn't have the ETA. Good thing I can wait as the car has been running really smooth, aside from the ticking noises during morning startup. This is the end of PSA. :-)

well add me to the list ... my passenger side is making noise so it's likely cracked. 54K miles and still under the CA Emissions Warranty luckily so the car is going in today to get this done along with the airbag recall.

the service adviser called and said they can't hear any ticking ... he swears both himself and the shop foreman listened to the car from a cold start and there are no noises. this is unbelievable since it does it every time i start the engine after it's been sitting for more than an hour. Hopefully they actually listen to it tomorrow morning and call me to let me know they verified the issue.

Just put headers on and let the engine breathe like it's suppose to

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.
