I know the ultraflows are gonna flow more, and are probably cheaper

But I really like the sound of the spintechs...

I'm considering the ultra flows and the spintech sportsman mufflers in the 3" size

Anyone know which will be the quieter of the two ?


Not worried about WOT, cause its gonna be loud no matter what, but I'd really like to have tolerable cruising.

Right now I'm running dynomax race bullets, and it's way loud on the highway, way loud at idle, and stupid loud at the track. People say its beyond loud and into pain when I'm at the track, and I hate the sound myself also.
