i also thought about that..
Peaceful yet loud outside and even louder when you put the pedal down.
They will break in after a couple thousand ( I say mine were about 6,000 miles until fully burned through ) but the interior noise will not increase a whole lot at all.

how do i know if my maggie is fully broken in? its a 4x9x14 siso that came on the truck when i got it. its got a chrome tip with some rust on the bottom, not much. so that tells it wasnt done too long ago. how loud would that size muffler get when fully broken in
