Performance exhaust option

[atom ant]

I have seen an upgrade exhaust available for the guys over the pond but couldn't find anything on this side. Does anyone know or heard of upgraded exhaust options for the U.S. K24 atoms?

I have not even seen a dyno of a stock K24 atom, let alone anyone showing numbers gained from any bolt ins such as exhaust or intake. Sadly much of upgrading the Atom is figuring it out on your own. It is one of the reasons I have been trying to post as much info as I can find in my autocross thread.
