What is the Mooney 'Anomaly'? 

A 1967 M20 F model equipped with a Lycoming 360. This aircraft has gone through extensive refurbishing and overhauls including a one of a kind paint job by Matt Kress featuring 40 different colors! Having completed a full panel upgrade adding to the ergonomics, Liam wasn't done modifying. He equipped his Mooney with our Power Flow Systems Inc tuned exhaust, reducing CHTs, and adding performance, efficiency and safety!

Liam's real world PIREP about our Power Flow Tuned Exhaust on his 67 M20F:

“Once The Mooney Anomaly received the PowerFlow exhaust system, we realized all of the benefits that PowerFlow advertises – improved climb rate, improved cruise performance at the same settings, and cooler CHTs!  Also, the ceramic-coated tailpipe looks mighty good on the Anomaly! I never imagined having people complement the look of my exhaust!” 

Bolt-On Horsepower. 

Complete replacement of the Mooney M20 exhaust system. FAA approved by STC for use with M20 E, F, & J models with Lycoming IO-360 or IO-390 engines. Power Flow offers configurations compatible with 200 HP Mooney’s equipped with either the stock Mooney cowling (Our Gen 2 system) or the LoPresti cowling (Gen 1 system). The Gen 1 system also accommodates M20-J models equipped with electric cowl flaps.

"We will be building highly-refined versions of the M-20 airplane in the year 2000." -- Roy LoPresti, president of Mooney Aircraft, 1985.

Turns out the esteemed Mr. Lo Presti was way too conservative! Although there have been a few hiccups through the years, this iconic design is STILL being produced! Many consider the 200 HP versions (including the M20-J vastly refined and improved by Mr. Lo Presti during his tenure at Mooney Aircraft into the superb “201”), to be the epitome of performance and efficiency envisioned by Al Mooney with his original M20 design from 1955.

Our well-proven Tuned Exhaust System (now installed on nearly 400 Mooney’s worldwide) gives your bird the superlative performance to match its rakish good looks and impressive pedigree!

Make your 200 HP M20 a faster, higher flying bird. Similar technology has been used in race cars and motorcycles for years, now it is available for your Mooney. By more effectively emptying the cylinders of spent exhaust gases, our Tuned Exhaust

System immediately gives your aircraft the following performance improvements:

• 5 -7 knots faster cruise speeds

• 10% – 15% increase in rate of climb

• 0.5 – 1.5 gph reduction in fuel burn at equivalent airspeed

• Improved Take-Off Performance (100’ – 300’ reduction in ground roll)

• Increase in Service Ceiling of 2,000’ – 5,000’

• Cooler CHT’s
