The smaller gas engines at least the ones I have seen perform just fine, Now if you need a racing engine tuned pipe and all glow fuel may be the way to go.
When I got in the hobby 20 yr's ago there were a lot of people running tuned pipes and ducted fan engines also Rossi and Dub Jett engines were popular
but I have not seen any of these engines or set up's in years.
