yeah, really. i'd like to know, too.. a lot of morons around my area are putting those $70 bumblebee muffler's on their trucks and it's sounding like a swarm of flies or some $hit. sounds like hell if you ask me.
do you have part numbers? is the turndown an actual part of the muffler or is it a separate part? can we list some part numbers, too? and again... anyone have any sound clips? thanks!!
