Questions about Canisters

       Remove this ad - become a site supporter!
Ok, I have a few questions. I will try to put them out here as clearly as I am able.

Is there anything inside the canister ?? chambers or baffles ? Or is it just hollow ?

I have noticed that the exhaust stinger has a smaller diameter than Pitts mufflers or even some stock mufflers. Some have said that they reduce engine power compared to a wrap around Pitts or Stock muffler.
True or False ?
I just read in an older post I had that some of you had said that Canisters can actually increase power.
I guess I should have reread my old post first
Anyway....Alot of you guys said to stick to a pitts style muffler for simplicity reasons.
Well, I want to use a canister style exhaust. I like the sound, and the airframe I am planning to use is set up for it. Weight is also not an issue for this air frame. At least from what I have seen on other forums and videos.

Do Flex headers have any negative effects compared to an application specific header ( smooth )?

Thanks again

Re: Questions about Canisters

Good questions:
Yes most good cans have a serious pathway designed inside them, this is the difference between a good can and a poor can. With enough volume (size of can) the can will greatly reduce the noise of the engine and you won't lose power, sometimes gain. If the can is to small it can reduce power and won't offer much for being quiet 'cause it will be restrictive. I hate pitts style mufflers! Flexible headers have their place, mostly convenience. They can crack over time within the flex. Fair amount of information on the internet about cans. You can even find some exploded views of the insides!
