I run a custom Spin. You'll might like the 6331. Go to the link
below, click products, click street performace and take a look,
see if there's something you like..I'm changing mine out. There's
nothing wrong with it, but it's time for me to get some quiet in
my ride. Spin's sound good, but can resonate. I want a
straight thru design now and with it a lot more mellow. I'm going
after a Hooker Maxflow. But if ya like sound either a Spin or
a Ravin Z55 or Z33 will fly . Link to both >
