There is a STC upgrade to 160hp if you so desire... Can still run on

It has a "PowerFlow Extractor Exhaust System" which is supposed to bump
up the bhp somewhat putting it possibly in the neighborhood of 160 hp.

Well with the 160hp upgrade, it would take it above that with the
PowerFlow system. PF is a nice addon if you don't have to foot the bill
for it... Old style put a long extended pipe on it, new design keeps
most of it under the cowling...
