Heads up: New Berk Tech exhaust
 

https://www.s2ki.com/forums/index.php?showtopic=542156

Check out the youtube clip - a very distinctive raspy noise. Any of the engineers care to comment on the unusual piping design?

That looks seriously loud but certainly very few places to restrict airflow, it's probably pretty well constructed as well. :) You should be able to order this from GTS Chris in the UK once it becomes available.

Still looks bloody loud though! :D

I'd like to see more detail of where the pipe splits.

For high velocity exhaust flow, there look to be a few sharp bends.
