I know these things:
A55 and A35 have different exhaust port mounting angles
They also have different rear mounts
With that being said, I've got an A35 reed kit on my dads A55 bottom end w/A3 clutches on a Arrow frame. (similar frame to the revival) We really like the MLM pipes because of the quality, R&D, reputation, and their side bleed pipes to keep it quiet.
We're looking at the MLM BK100 because he likes low down power and torque, but it's only listed for the A35.
Since we're running the A35 cylinder on the A55 top end, will an A35 pipe bolt right on? How far off would the rear exhaust hanger be?
I have no problems welding pipes to adapt them or fabricating hanger adapters, but it would be nice if a pipe would be very close to bolt on, especially if it's already powdercoated.
Other options:
MLM cali pipe for tomos A3/A35 with side bleed
MLM tomos A3/A35 people's sidebleed pipe
MLM cali pipe for tomos A55 with side bleed
MLM tomos A55 people's sidebleed pipe
BK100 dyno run:
St. Ripper dyno run: (I imagine the cali and peoples pipes are similar to this one)
