Pipe looks great
but that old prick leaning on the truck is spoiling the shot
Seriously though as well as looking a shit load nicer than the original it looks way less restricted than the original , which if I remember correctly was as flat as a plate of warm piss through the guts
Over the last 20 yrs or so I have tried all different aftermarket chambers on all different bikes
and without exception the pipe that made the biggest performance gain by a country mile is Geoffs Pipe for a YZ 125A
I have had it on a YZ 125A obviously , MX 125A , DT 125 A , DT 175A and am currently adjusting the arse end of it to fit an MX 125C
