DR650 96′ to current Suzuki DR650 SS Pro-Flow Headpipe by Procycle USA. Procycle high flowing head-pipe is made in the USA using a C&C computer numerically controlled mandrel bender for an absolute perfect fit.

Note ours is a early model and varies slightly, the newer models have a welded join like the FMF Header – Mal
