Testimonial: The exhaust on my Cessna A185F on Aerocet 3500L has made a difference. Yesterday, I left with full fuel, 4 people, baggage with 90F temperatures and no wind. With the new exhaust, the airplane is an animal, breaking the water and climbing at 1000 FPM. The exhaust lowered my CHTs by 20-30 degrees, evened out my EGTs to +/- 40 degrees and increased my airspeed on floats 2-3 knots. Overall, I couldn’t be happier with the new exhaust.
