Found this advertised on Craigslist as "Greedy Rx7 mufflers" Needless to say I was skeptical...
However, upon arrival I discovered an authentic Greddy Power Extreme Catback with Bonez midpipe for sale for $180!!!
To further sweeten the deal I sold my stock turbo exhaust for $50, and the midpipe (its for n/a) for $80.
