Hey guys, does anyone know if the Akra exhaust for the LC4 is same for all models? I've been searching endlessly for a full system for my 2006 625 smc but they are hard to come by. I'm wondering if any Akra exhaust built for LC4's is interchangeable and essentially the same part. For example will the same Akra header fit 2002 640, 2003 sxc, 2005 smc, 620's, 625's, 640's, adventures, supermotos, so on and so forth... I know all the motors are relatively the same so there's little worry about bends and clearing the electric starter housing and what not but more into detail, was the Akra header the same for the original vs the newer high flow head? I don't expect an easy answer but thought I'd give it a shot.
