hey it is true that we can change the exhaust pipe to any thing that we like,
saw it in the newspaper but not sure if there is any hidden rule or restriction to the size and ower of the exhaust pipe
mus buy a only street legal system tt has been approved by LTA n after installation mus bring to LTA for inspection n photo taking.
mus carry the street legal certat all times n present to any TP or authority wen requested. Pipe cannot b tranffered to other bikes w/o going thru the entire inspection process again.
