I've heard the Pro Circuits and Aliens on a V, alittle too loud for my wifes taste, how does the Yoshi compare as far as db and what about Muzzys?

 

I have the dmc alien duals. They are loud, but I like the power gain over the stock pipe.

 

If I could buy any kind of exhaust tomorrow, I'd get the LTE duals. My second choice is the Muzzys, which I have. I have heard that the DMCs are good, next in line after the Muzzys. The Yoshis I think make the least power out of all the popular pipes for the V.

 

Aliens and the HMF's are going to make the most power over anything else as long as noise isn't a factor.
