I really like my B11 except the pipes. Does anyone know where to buy doubled walled pipes or anyone that can make them.
 
Presumably the Genuine double-walled pipes as fitted to the later/current models should fit.

Some, like Kiwi Dave, have opted to have the headers ceramic coated.

I don't like my Breva's header pipe look much either, but not enough to do anything about it, but if the urge came upon me I'd follow Dave's example.

Didn't you launch another thread on this in which I replied that someone (Moto International?) put the complete 1200 Sport exhaust system on a B11, double walled headers, x-over and catalysed carbon(look?) muffler? Apparently works fine, breathes more freely, and is still completely homologated.
 
I did start the other thread please accept my apology. I really thought the 1200 and norge had doubled walled pipes but the dealer said no and it would not fit my Breva. The spots are really bad looking. I kind of knew they would be expensive but just wanted to find out if there was any other option for the pipes. The dealer told me that the pipes will still burn with double wall, but I am not sure about that. The Harley's have the double walled pipes or a chrome cover on them and they look good. SOOOO why can't the people at Guzzi or some after market come up with a set of pipes that will not burn or if it does cover them up.. Any idea how much the pipes would cost????
The ceramic was another idea or powder coat them but was not sure about the heat transfer. Dealer said the powder coat would cause the pipes to hold more heat on the engine and believe the engine has enough now so I would want more heat. The ceramic coated pipes looks like they still are burned some. Is this so or does the picture just look that way????
thanks

My dealer told me that this is just the way they are and nothing could be done to fix them. He said even Guzzi knew and would do nothing when the bike was in warranty. They are suppose to be stainless steel. Not sure what grade.
 
Stainless can be buffed out to look like new again. If you're concerned about spots, it's probably oil or fingerprints that get baked on the next time it gets hot. It's always going to turn yellow, though.

They do still tarnish with a double skin, but to a much lesser degree. I have done about 700 miles on my 1200 sport so far and it is tarnishing near the head, however a bit of 'Autosol' or something similar would bring it up very quickly. On the Breva 1100 I found the best thing to do was to take the headers off every few months, put a buffing pad on a bench grinder with a bit of polishing compound and then it only takes about 15 minutes each to bring them up good as new.

The ceramic coating is apparently applied to both inside and outside (although I have no way of checking the inside without cutting them up). The heat on the pipe therefore less. I guess the only way to check this would be to just ceramic coat one pipe and do spot temperature comparisions. I only coated them for cosmetic reasons.

The finish is sort of semi-matt (or semi-gloss) so there is a bit of sheen apparent. Below is a picture of my friend's Beva, which inspired me to do the same. He chose an aluminium finish, I chose the black. Other colours are possible too.
 
I'm still a bit in the weeds on what is going on. The only other Guzzi I had was my loved 99 Bassa which has not moved on to my brothers hands, and it's pipes too did discolor, though not as fast and certainly not as much. They where SS. I just assumed that the Breva must not be SS as the rate and degree of tarnish is substantially more pronounced.

I'm am just wondering what material the pipes are made of, and does the higher state of tune of the Breva motor have something to do with it? Will Blue A-Way do anything?

It's not a big deal for me, I love this bike, no stinking yellow pipe can change that!
 
The B11's engine runs very hot. A French friend who spent some time in California and had a B11 there (some of you know him, Olivier), told me several times that his header pipes sometimes went glowing hot. I still can't believe that's normal, though.
 
I'm more for riding and less on polishing, hence my bike looks "used" rather than shiny.
If you don't polish the pipes at all they eventually go a deep matte colour and the liver spots aren't really noticable.
Whatever coating you use, whether ceramic or heat resistant paint, it will always fade.
Give it a few years and i might even give the bike the "3 cans of matte black" treatment :evil:
