Overview
|
Bolt-On Horsepower. Complete replacement of your exhaust system. For Grumman Tigers (all years) with Lycoming O-360 engines. You have seen similar technologies in race cars and motorcycles for years, now it is available for your Grumman Traveler, Cheetah and Tiger. By effectively emptying each cylinder our true tuned exhaust will give you a number of benefits. You will immediately notice an increase in RPM (30-130 more) as well as a significant improvement in rate of climb (avg. 200fpm). You can use less throttle to go the same speeds and save up to 2.2 gallons per hour. The Power Flow is a versatile, quality constructed, complete replacement of your entire exhaust system. You are in control. For more power, use the extra RPM. For fuel savings, throttle back and fly your pre Power Flow airspeeds. The entire system is constructed from stainless steel and includes minimal structural welds in the cabin heat section for improved safety. All necessary parts are included for easy installation on your Grumman Tiger. Our customers report an average install time of between 5-9 hours. |

Per supplier: The Ceramic Coated Tailpipe is an optional upgrade we offer for all of our Tuned Exhaust Systems. These systems are fabricated entirely from 321 Stainless Steel, generally considered one of the best materials available for an exhaust system. Unfortunately, Stainless Steel discolors when it gets hot (like the muffler on a motorcycle). This discoloration has absolutely no effect on either performance or reliability and the original polished finish can easily be restored with an application of stainless steel polish. If the customer is proud of his airplane’s appearance, though, and would rather spend his time flying than polishing, the Ceramic Coating on the tailpipe covers the discoloration up permanently with a shiny silver finish. One note of caution – we have had very good results with the Ceramic Coating on most of our Tuned Exhaust Systems. On the Grumman AA5 series aircraft, though, it does not hold up as well as it should. This is because the engine’s in the AA5’s frequently run a little hotter than average, causing the Ceramic Coating to flake-off prematurely. I therefore usually try to dissuade Grumman owners from adding the Ceramic Coated Tailpipe option to their orders.
