It wasn't that long ago that Joe Fabiani decided to make a custom exhaust system for his Porsche. A member of the Porsche Club of America (PCA) and racing enthusiast, he soon found himself making exhaust systems for fellow PCA members. That led to founding a company, FabSpeed Motorsports Inc., which initially relied on outsourcing for nearly all of the fabricating. Fabiani recently opened a new division, FabSpeed Precision Services, and invested nearly $1 million in equipment in the new division to eliminate outsourcing.
