I would like to use a canister muffler in my 28% Edge that I'm getting that will have an Evolution 58. Is there anyway I can do this and still mount the fuel tank under the wing tube? Someone mentioned a way to "lift" the tank tray to get it to fit.

So, I guess I need to ask Tom about this. He sells the muffler i'm buying plus he could tell me the difference between the "power" Bisson muffler and using a canister. So Tom is there a difference between a canister for the EVO 58 and the "power" Bisson muffler?

They are completely different, I don't really understand the question.

Sure, is there a big difference in the power the engine puts out between a canister muffler and the power Bisson muffler you sell for the MVVS/EVO 58

There should not be a big difference, but I have not yet tested it.

Here is the situation.

I tested the MVVS/Evo 58 first with a Slimline muffler modified from one for a DA50. That one did 6800 rpm with a 24-10 Mezjlik prop. This muffler has 7/8" OD outlet pipes.

I then retested it with a header/canister setup. I expected great things, but was disappointed to see that it was exactly the same 6800 rpm.

I have run the same engine on our newest Bisson quiet muffler with 5/8" outlets but have not measured it with a tach. IT seems to be down on power from the canister/slimline which is expected by my observation, I'd guess it's in the 6300-6400 RPM range now.

I also now have a Bisson muffler with 7/8" outlets but have not tested it yet. I am expoecting it to be similar to the slimline/canister setups.

Remember that with the Bissons they crimp the tips of the outlet pipes down to a very small hole for noise reduction. You can always cut off the tips to decrease backpressure which in most cases will increase power.

Ok. Sounds like the power Bisson will probably be about equal to the canister since it has 7/8" outlets. Should be open enough to allow the engine to breathe.
