This looks like old news but I came across this today (really slow day at the office...) From the land down under, a Subaru powered lawn mower! http://www.ryobi.com.au/Products/PowerGarden/Petrol/Lawnmowers/RLM4619SME Looks like they have a pressure washer too.
Yeah, there are alot of Subaru Robin powered snowblowers and pressure washers around. I know I've seen them for sale at Home Depot in the past.
What's the best exhaust to get the deep rumble? Also, which bov will be the loudest when I let off gas lever?
