Has anyone tried a gpr exhaust on a buell, looking at removing my drummer exhaust in favour of something quieter. Have also looked at torque hammer but a lot more expensive.

Have you considered an Albert? They are highly regarded.
You can contact albert666 on here by pm or take a look at his site:

Had a GPR on my last Guzzi, very good value and quality, but it didn't vibe like a buell does so can't vouch for longevity.

Think I am now looking more at the torque hammer and map it's getting some very good write ups and a lot of people are saying it's quieter than most other buell exhausts

Have contacted albert, waiting for a reply.
What map have people used with his exhaust, one of the reasons for looking at the torque hammer is you can buy there map and I can find anyone trusted to dyno it!

I had an Albert on my XB. I never touched the mapping, which I guess was standard, ran fine.

If you're getting rid of the drummer, I'm looking for something a little louder on the XB. Spent a week being shown up by guzzi v11 :o Ended up just wiring the standard exhaust open to get a little more volume.

Oh as a side, wiring the exhaust valve open, when the bike was cold it was a bit of a pig, but once warmed up, no real difference in performance.
