There's a hole in my header, dear Liza, dear Liza

After having my front coil, ECU & dash replaced recently, and circumventing the labour cost for fitting them by having my Desmo service done a thousand miles early, I received another wonderful piece of news; my rear header is cracked.

I haven't had time to check properly but I think from what the tech described to me that it's under the heatshield. He said you can see licks of flame from it if you look carefully when running.

So we chatted about upgrading to the Akra header, and he said that I'd really need to go with a fuel controller of some sort too if I go down that path. I mentioned the fact that a few of you guys have had good things to say about the Rexxer unit and he agreed that it was great and would be well worth it.

So they can source the Rexxer + fit it for £200, and the header would be about £900. As I'm saving to move to Australia, I need this expense like I need a hole in the head.

So my question to you guys is how long do you think I can get away with running with this crack? Do you think it's worth leaving it as long as possible as is, waiting until I have funds to spare, or should I just whack this on a card for the bikes sake? I don't wanna risk any other damage due to this.

I know when the crack appeared now I come to think of it - about a month before I got disco dash there was a definite period when I can remember the exhaust started popping a lot more on deceleration - obviously cause more oxygen was entering the exhaust up near the head...

My input...

I wouldn't run it too much as-is, because the cold air in such close proximity to the valve can damage it.

I would find a replacement stock piece. There are many people who have swapped exhaust systems and have these pipes laying around. You can probably find that part for $40 and be on your way. That would take some time, so a quick fix would be have a welder weld it up with some reinforcement plate.

If you really want to tune it, Rexxer is a good option. It's less flexible than an aftermarket tune from what I understand. Maybe ferdi can provide more input. Basically, if you change anything on your bike Rexxer must provide you with a new map, ideally using dyno tune information. A fuel module lets you alter the tune on your own. Of course all this is really only worth it if you have complaints with the bike's runnability.
 
Thanks for the advice guys, you're right about bad luck alright dragon, seems like I've not only had all the common issues to be found on these bikes, I've had some decidedly uncommon ones too.

Anyway, thanks to your advice kuksul, I've managed to locate a used stock piece for about £50 - only one I could find. I'm holding off buying it until I verify exactly where the crack is, which I'll try and do when I get home in a few hours - appreciate the link which contained a video, hopefully it's in the same place.

So next question - has anyone had any experience removing the rear header?

When the tech was describing the removal procedure, he said that there is very little room to work with, and that Ducati supply them a special tool to get the stud nuts/bolts (can't quite remember).

Time is a bit of a premium for me these days, so I might just call up the shop and see if they'll fit it for me for a reasonable price. Unless someone here has done the job before and can tell me it's not a total SOB/PITA job anyways!!
 
Joke, I think the big stopper would be if you have to pull the fuel tank. I've done headers on cars and usually the only PITA part is clearance to break the bolts - which I'm guessing is an issue if they supply a special tool.

You almost always need a new gasket when replacing intake/ exhaust manifold parts, and they usually aren't cheap. I'd cruise the .ms forums for info on full system jobs. If they don't have to pull the tank or remove the sub frame, I think it would be a relatively affordable job to have a shop do.

Good luck, Mate.
 
So went to the dealer, they reckon 3 hours labour to replace the header with a 2nd hand stock piece. It does look like a ****** job after getting up close. So £250. Great.

I managed to cut a deal if they add the Rexxer map at the same time for £375, and also asked if it might be worth adding some plate to strengthen what is obviously a weak point. The tech reckoned it was a bad idea as an additional weld would attract corrosion - which is very much a problem in this country.

Booked in for Jan when I get back from Australia. I ****** wish I could afford the Akra headers, but this Brexit **** has ****** the value of the pound - they were ~£700 when I looked months ago, but ~£900 now.

At a time I'm looking to emigrate, I just can't justify that cost.

On the subject of exhausts, what do you guys reckon is a reasonable price for a 2nd hand, <1000miles use SC Project CR-T exhaust? It's up on ebay, have relisted a couple of times, but no takers. I'm asking half what I paid for it and its in great condition.
 
i think the thing about selling your exhaust is that there are a lot of different styles available for the strada .it is just a case of finding somebody that wants that particular exhaust. It might be worth trying putting on a price with "offers accepted" or just put a reserve on it and put it up for auction.
 
After looking closely, it is rather tight, but I think with a combination of 1/4" 10mm socket on a u-joint, and a 10mm open-end wrench you could do it yourself. The 'special tool' looks like a box-end wrench with a jog in it just to get easier access. It probably helps the shop do it in 10 minutes, versus 20 minutes at home.

Would you consider painting the pipes for rust protection?
 
Here's a pic for those that asked:



Looking at the job, I have to admit, I find it pretty intimidating. Perhaps if I had a day to spare...

Do you think any paint could stand up to the heat? I've seen the header glow red before...
 
Is this not a recall? I feel like you could probably make an "increased emissions" plea to the right district manager and get some traction. Being in Europe can't hurt.

If coming out of my pocket, I'd lay the bike up for a couple days, remove it myself and get a good shop to throw a bead on it. Even having your shop remove, let you take it in for a weld, then replace would be cheaper than buying a new header. Or go full ****** and use the opportunity to buy a full Akra system.
 
I wanted to go full ******, but ******* Brexit has weakened the value of the pound so much that where the header used to cost £700, it now costs £900. *****. I just can't afford to part with that much cash.

So far, I've got a 2nd hand piece that I located for the princely sum of £50, now I just need to decide whether to have the shop fit it for £250 labour alone, £375 with a Rexxer tune (this comes highly recommended I hear), or whether to just tough it out on the driveway to get it fitted (which, considering my serious lack of spare time and ****** British weather, is looking pretty unrealistic right now..)
 
just got my bike back from service and they say mine is cracked too.
I used to stick up for my ducati ,as people say they are unreliable .But after recalls for throttles ,can wiring to the dashboard ,missing steering bearing dust covers and now having found the exhaust cracked (i have noticed the front discs pulsing now too.)I have come to the conclusion that they are by no means manufacturing defect free.
I have a fire blade with similar mileage on it and had a 1st generation 1999 yamaha r1 with 24000 miles on it and neither ever needed anything other than brake pads and chains.
 
Mine is cracked too. Just found it today. I just... WTF DUCATI!!!

Luckily I had already bought a spare for a project I'm working on, so there's that. Replacing it was not easy. I had to take the fuel tank off (what a PITA job that is), and modify a 10mm socket to fit in there and unscrew it 1/8 turn at a time.
 
Sucks. I had my dad check mine since he's watching it while I'm away. He said it's good.

I still say it's how the manufacturer handles these issues that counts. So far, Duc or the shop has resolved all the big issues listed above.

Don't think every bike they make rolls off the line flawless. It's like when I bought a new Acura years back. Tons of recalls. Same thing on that forum - lots of "WTF" and "POS". My sister bought a Mercedes thinking she was buying automotive perfection. That thing fell apart worse than my MK III VW, which was bad.

I don't think comparing to the Japanese market bikes is valid. You're talking about models that sell probably 10 times as many units. They certainly have issues but it's just a smaller reported percentage or not reported at all. They also chose the simple and proven design of the inline 4.

Just keep us posted on how it's handled. This is a brand new motor design.

It can be hard to see the crack when cold, and it opens up when it gets hot.

I'm not giving Ducati a pass on this one. My mid pipe cracked as well, shortly after purchase ($475 part). It's a welded metal pipe; car and motorcycle companies have been doing this for decades, and yet they still somehow failed at it. It's just frustrating. My other bike lives outside and its header pipes are all rusty and pitted - but no cracks.
 
Glad I'll be back in FL when I get back to inspect. My original dealer was very good at keeping me happy.

I always knew when I had a cracked exhaust/ header pipe in a car. You could always hear it and feel the sapped power. I'd be shocked to find mine cracked as it never felt weaker. No symptoms?
 
No symptoms, although to be fair I didn't know this hole (which has now become a crack) was there, although there was definitely a point when the exhaust started to pop more on deceleration. I just thought it was my Akra bedding in...

Does anyone think it would be worth us contacting Ducati as a group over this?
 
No symptoms on mine, just a hairline crack about 1 to 1.5" long. I will grab a pic. I didn't notice until I took it off for other reasons.
