Silencer Corrosion!

[aerodyne]

When I bought my Guzzi in 2007 I was really impressed with the quality, this compared to other bikes I have owned over the years. However having ridden it through a couple of british winters I was a bit miffed to see a number of small pin holes appearing on the silencer sleeves, these pin holes were weeping what looked like moisture. Anyway when dried, a little Araldite mixed with black paint carefully applied to the pin holes and they dissapeared. Last winter some of the holes became a lot worse so time to investigate. When silencers removed I took off the sleeves only to find the inside part of the silencer made of mild steel, this wrapped with what looked like a thin piece of fiberglass and the aluminiun sleeve telescoped over. I can only think that moisture getting between the sleeve and the inner was causing some sort of reaction between the steel and aluminium, hence the corrosion and subsequently the pin holes. Conclusion, throw away these poor quality, heavy, originals and fit something lighter and better in appearance. I looked at various options all of which were very expensive and difficult to get hold of. I really wanted the silencers to be higher than the originals, as I don't carry pillions on this bike I did not mind removing the rear pegs. Anyway after many hours of thought and measureing, I came up with what you see in the pictures attached. The silencers were bought from a company called DTC in the UK, they are trioval titanium 380 m/m long fitted stanless steel end caps, the link pipes I made up myself from stainless steel 45 degree elbows TIG welded together, the hanging bracket again I made up myself. The result I am pleased with, sound is awesome. The originals in the bin!!!
