Project S2000: Upgraded to an ASM Special S Exhaust 

Yeah I remember that about my old ballade one which is likely why it's very quiet. I believe the ASM one does not from what I could find. It is noticably louder than the ballade sports one but that may be a result of the exhaust packing being a bit more worn. I've seen comparisons of the ASM Special S 60mm vs 70mm and the 70mm does make more power

So when you look inside your new ASM muffler, you don’t see a smaller diameter inner pipe?

No taper in the internals

I got it built from a local fabricator. I had used my old Ballade Sports exhaust as a template for the Helmholtz resonator

@@jonyrho Would you care to share the measurements of where the Helmholtz resonator is? I see a v1 locally as well, and I'd be interested in adding one.

Sold already! Sorry!
