Not sure about that answer, Motolink. I do know a great pipe guy in Carrara,near Nerang : Noel Rogers of "pipework techniques" Ph.07 5559 0255
He built & rebaffled my pipes. Mebbe speak to him
Blasted bones, I am told someone in Brisbane debaffles the stock mufflers on a Roadster and makes larger crossover pipe as well. Do you know who this is and have you heard the sound?.
I've been told it's the guy just off Moss St. at the intersection. Been thinking about getting mine done but haven't heard one yet and don't want to stuff it!
