What Power Flow Systems does

Power Flow Systems, Inc. is a privately held aerospace manufacturer founded in 1997 by Robin Thomas and headquartered in Daytona Beach, Florida, specializing in FAA-approved (STC and PMA) tuned exhaust systems for general aviation piston aircraft. The company's core technology adapts 50+ year-old motorsport scavenging principles to the confined cowl spaces of light aircraft, hand-crafting each system from aerospace-grade 321 stainless steel with vacuum-annealed collectors, argon back-purged welding, and a proprietary perforated-tube muffler insert wrapped in INOX stainless steel fibers and BASALT. The product delivers documented performance gains of 10-20 HP, 30-130 RPM, 100-250 FPM climb rate, 3-11 MPH cruise speed, 0.5-2.5 GPH fuel savings, and 15-20 degree CHT reductions, with coverage across 35+ aircraft/engine combinations including Cessna, Mooney, Piper, Grumman, Diamond, Beechcraft, Aviat Husky, Glastar, Symphony, and Robinson R22.

The company makes money through one-time sales of custom-built complete exhaust kits (4-6 week lead time, $1,500 deposit, balance due before shipping) plus an aftermarket parts stream, RMA/rebuild service revenue, and a Preferred Dealer channel that captures installation margin. Go-to-market combines dealer-driven installation sales, direct phone/quote and Ecwid online-store transactions, and an event-driven presence at major GA air shows (Sun N Fun, EAA AirVenture, etc.) with progressive show discounts and lead-time incentives. Customers are predominantly individual general aviation owners and small flight schools, with brand-ambassador and YouTube influencer marketing layered on top. In January 2020, Power Flow acquired the assets of Leading Edge Exhaust Systems, materially expanding its product line into six-cylinder Cessnas and additional Piper models, and in 2026 it relocated to a larger facility at 574 LPGA Blvd, Daytona Beach. The company is closely related to Laminar Flow Systems, Inc. (a Robin Thomas-led maker of Piper speed modifications) and operates Challenger (filters) and Maple Leaf (fairings) sub-brands.
