Ok.... but statistics about manifold breaking and causing damage ?? Sent from my iPhone using FerrariChat.com mobile app
I know of (only) one massive engine damage due to manifolds failing. However as this engine damage is caused by failing manifolds the damage to the engine if a "follow damage" and therefore covered by insurance. If this applies in US I don't know. Note: The manifolds are not covered under warranty in EU as in the US it is (within 8 years). pics of that case in 2014: Image Unavailable, Please Login Image Unavailable, Please Login
I agree, however if you still have full warranty on the car (Ferrari warranty program) you have to use stock parts and installed by official dealer. When you install after market manifolds you will fail on the next warranty inspection.
Let’s not even go to possible engine damage due to cracked OE exhaust manifolds. Why would anyone spend ~$90K ($15K X 6 )on multiple exhaust manifold replacement costs if they have the option of going with an aftermarket headers that costs ~$6k one time charge for parts and labor & has lifetime warranty and been proven in service that eliminates cracking issue? Note: I was quoted by a dealer $15K to remove and replace F430 OE Exhaust Manifolds. So I said no thanks. I installed Agency Power Headers and Kline Innovation Exhaust on my F430 for much less price, better made, better design. Problem solved. Im not arguing, I’m trying to understand the reasoning and logic behind that decision. Maybe I can learn something new or see an angle I have not seen before.
Good point. But what about car down time unable to drive your car? The amount of time it took to take the car back to the dealer six different times to address the same issue. Worrying every time you drive your car that the exhaust manifolds can crack and may damage the engine which would be a much bigger cost. To me, you cant put a price tag on peace of mind.
Well I can’t speak for someone else, I’m just trying to find out the statistics of actual engine damage from manifold failure... it would be interesting to know. We talk a lot about manifold failure, but actually I dont know what the stats are on actual damage to the engine. I can’t speak for anyone else and I’d never discredit someone else’s decision without knowing why they made that decision. I’m simply asking a question about my own risk.

i wonder if a car started from zero miles with test pipes or hi flow cats wld the exhaust manifolds still crack or just much later?

I was quoted by a Ferrari dealer $15K to remove & replace both exhaust manifolds with Mark 2. $5,100.00 each side, plus labor, plus replacing the cracked exhaust brackets. I did read here somewhere costs similar to what I was quoted. Here's one: https://www.ferrarichat.com/forum/threads/any-f430-owners-have-their-exhaust-manifolds-go-bad.203537/
2004 360 52K miles / White dust in engine compartment & faint ticking sound were the signs that prompted Mechanic to scope and sure enough pre cat was broken up inside and headers had cracks. Now waiting for Fabspeed headers & Evoflow cats to arrive and get installed. PS this thread isn't very accurate because it doesn't state 360 or 430
Hey Dan! I would probably go aftermarket if my manifolds fail but the reasons why I like the OE manifolds: 1. I love the way they sound! 2. No CEL lights 3. No issues with being compliant with emissions . 4. Currently have the MK11 . - so far so good
The challenge w a poll like this some current owners are not going to want air dirty laundry about a car openly for when they go to sell.... nature of car biz I guess.
Tt- I agree but not all people will feel this way. some get scared away by ‘issues’. just my opinion. 2 cars- 1 says had header issues, and other says nothing. could affect a buyers interest. particularly the usual first time f car buyer.
They are supposed to be stamped/marked somewhere. For me it was an easy decision, upgrade to a better designed & better made headers. Can’t put a price tag on peace of mind. I installed agency power headers and Kline exhaust. 1000% happy. Dan
Easy to see when you look at the plate on each manifold: When it states Ferrari + partno. and Arvin Meritor (=manufacturer) it is a Gen I. When it states only Ferrari + partno. it is a Gen II or higher. See pic below of Gen I plate. Plate Gen I: Image Unavailable, Please Login However as I discovered the Gen II is not fail free... Just brought the car to the workshop last week to do the 70.000km maintance and got a call. The Gen II (right side) is cracked. I had the rear brackets (on the gearbox housing) removed to release heat tension on the heathers, but did not work. Pic of bracket showing the tension crack. Removed this bracket to prevent cracking of my Gen II heathers. NOT!... Image Unavailable, Please Login As I have the original (=Gen I) heathers home (replaced at 22.000km), so I opened up to investigate the issue. It is open at cil 1 all away around and maybe can be fixed/welded. see pics below. When I pick up the car next week I will also open Gen II to investigate how and where it is cracked this time. As the replacement is offered to me free of parts I go (again) with the original, also as I understand the new batch of heathers has been modified. Pics Gen I cracked at cil 1: Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login As I am not a welding expert I wonder why the metal (stainless) cracks at the weld/pipe edge. The weld is strong enough but it seems the metal/weld does not blend. Can it be the electrode? Or wrong amp's? Any experts? Also looking inside the pipes at the weld, the weld is not always full through 1 is ok and blends, 3 are wrong. You can see the edge of the flens and pipe not blended... Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login Is it likely that the poor welding cracks to? Any specialists here to commend?
Ok, I personally would much rather go aftermarket to eliminate the issue instead of revisit it. My question is does aftermarket always throw a CEL? or can this not be fixed with a tune?
Thanks for sharing info and your experience with the OE exhaust manifolds. Sincerely appreciated. Dan
I have Agency Power Headers and Kline Innovation Exhaust on my now sold F430 Spider. Zero check engine light.
