Exactly. Maybe it didn't cause the failure. In fact, it probably didn't. But it IS possible, which gives Nissan enough ammunition to deny a warranty claim.

no cats would have yielded a cooler exhaust flow in that area, but that is def not important here. good luck man. i had slave cylinder issues in my old IS300. went thru two of them. less than a $100, so just eat the bill.

Maybe others beside digi.. Can confirm if they have had high flow cats or test pipes and ran into this problem..

I didn't have my HFCs on very long. I want back to stock in December. My CSC was replaced last month. I just got word that abnormal bearing wear from poor design and the seal slipping and cutting itself were the causes.

I've had mines prolly for like 3 months.. I'm just gona take em out put the stocks and try another dealer.. Do you guys recommend taking off the whole exhaust out just in case? They say something else?.. This is my last try.. After this I'm just gona buy the slave from nissan and have it done at my friend's shop.

i would just pay it and get it over with. then somehow install a heat shield for future...

the more backpressure at the cat means more heat build up. HFC will be less hot than stock but still hot!!!!! so a shield might be needed. test pipes have zero build up. the hot gass fly out the exhaust.

CSC is about $100. Tech docs suggest changing the metal tube because contaminants can damage the CSC, My dealer kept the old one on. :icon14:

the replacement part in question is $100?

The labor will be the killer though.

well if his warranty is already void, he can have it done at another shop.

Yes, but what Lou is trying to tell you is that if you have paperwork, then that paperwork has already been entered into a dealer-wide network in Nissan's database. What exactly do the printouts you received have written on them?

This is one reason I have mentioned that if you are doing your own oil changes, and buying Nissan oil from a Nissan dealership, the dealership will enter this into Nissan's database for your 370Z's VIN if you ask them to do so.

Well he entered in the paper.. "Customer complaint about clutch pedal", car has aftermarket exhaust which runs too close to the clutch lines making the fluid boil to a high temperature. This is what the service sheet said.. I wasn't charged for anything though.. I don't think they even touch the car.. Fluid was at the same level as when I left the car... Dealer wanted to charge me $780 for labor and part

Just take it to another dealer and see what happens. You might get lucky.

Problem is your VIN and other pertinent data to that VIN is being collected. Maybe Lou will chime back in here, but I think you're f'd on this deal.
