Exhaust systems

Hello everybody,
I own a Breva 1100.
I have removed the belly pan and installed a Y pipe (see picture below) and Mistral reverse cone exhaust can.

Now I have the opportunity to get a set of headers+”pretzel’ from a 1200 sport/Bellagio for a few bucks.
Apart from a small adaptation it a straight forward installation.

Ok but why would I do that???
One reason is the looks. The double-walled headers definitely look beefier and are easier to keep shiny than the single walled of the 1100.

The other reason has to do with performance.
The 1200’s system is a stock design. It is shaped like that for a reason.

On the other hand the aftermarket Y pipe is a piece that siply connects the headers to the can. Its well made and looks like the obvious solution but it's not the product of a fluid-dynamic design. Afterall why Guzzi didn’t go that way for the 1200, instead went for a more complex design? There must be a reason… (GRiSO’s pretzel lesson).

Long story short, what is your opinion about it?

Should I go for the 1200 system?

Will I gain anything apart from the looks?

Thank you!

To be honest I don't think it will make much difference either way. Really it will simply be a matter of which you prefer and which one is more convenient.

Breva pipes are double skinned as well if they are the originals.

Thanks Pete.
Well actually the model with bellypan use single wall headers (Breva 850 and 1100) while the Breva 1200's are double skinned and no belly pan.

Anybody else has any similar experience?

The Breva 1200 was usually a Sport, though there are a few actual 1200 Brevas around. I would stick with the Sport setup, the pretzel will offer lower and mid-range torque.

Just my humble opinion though.

Thanks Tony
