I am getting really tired of this loud noise from my muffler. I can be going 5 mph and it sounds like I'm blasting off to space! A silencer helps a bit but whats the point of having a performance muffler if your going to cap it off...

I am looking for a good performing muffler that wont attract the cops. I care 60% about the noise, and 40% about the performance. I don't want to go back to stock, but if it can be as quiet as stock, with better performance then please let me know. Anyone know of any brands that has low DB but still performs well?

Also... just wondering if anyone heard of the twin looped mufflers?
