Cyclic Hardover... question for you. Are the Pitts style mufflers noiser than stock? Do they provide any added benefit?

I ask because I was thinking that I may switch over to that type of muffler for my current build and want to know if the Pitts will make a noise or performance difference. I am building a Tiger 120 with an OS 1.20 AX. (hell, I am not even sure if the Pitts style is available for that engine or not.. just in the inquiring stage for now.)

Thanks.

DS.
