This video doesn't really do them justice. The tone is much lower, and under load they are much louder with more of a rumble. You can really hear them good when the trans downshifts (auto) .... They get that nice rumble ..... They are quiet while sitting at an idle, but get very racey under WOT .... I'm very pleased with them, and they made the wife smile also ..... SOLD !!!
I'll get some better vids with my video cam next go around .....
