Here's a pic of a KX 450 that will be featured in the upcoming edition of VMX magazine, should be some better pics in the edition.

One thing I will say about the pipe DO NOT have it stamped or hydroformed. They are not better nor do they make better numbers. Also the join at the end of the belly and the baffle cone must be clearly defined and 'sharp', as shoud the belly and various stages in the diffuser cone.
