Hello, i am trying to get a pitts style muffler to fit under the Cowl of my F-1 Kyosho Kelly. Is it all right if i shorten the exhaust tips, will it have any affect on the engine??? Any help would be appreciated

G'day Mate,
If you cut the tubes it will change the tuning of the engine, usually makes them sensitive to needle valve adjustments.
Make the hole bigger in the bottom of the cowl, you will need to to keep it cool anyway.
