The dynamite 086 and OFNA 086 (or Novarossi or any other 086) are all the same design. Same with the 053'3 063's etc.
The quality of construction and materials may differ though
the Dynamite pipe and OFNA pipe are nothing alike..the OFNA pipe is louder ( much much louder) and to me makes more HP....
The Dynamite 086 is hard coated and has a different header, but the design is the same. OFNA headers can be notorious for not being aligned and restrictive. The dimensions of the pipe however are the same. which is what i said in my post.
just becaue they are noisier and give different power output doesn't mean they are not the same design.
hardcoating can provide more noise and different power profiles as the resonance is different. Do a search on OFNA headers and you will see some of the power issues with them and the fixes
