Arlan is a honda guy. One of the best. If you want the same for a suzuki go to jerry. Not to dismiss arlan. He takes his work seriously and takes it personal if you have an engine failure. The amount of R&D time into developing a pipe is not something he is into unless there is demand. Jerry has already done that and more.
Just my .02.

That being said my led Honduki runs hard and I'm happy with it. Made low 70's hp on his dyno. Somewhere I have a vid of it....
