T-409 exhaust
I bought one and am very happy with it. Sound level isn't as loud as I was led to believe - I would prefer it to be a little louder. Maybe its because I've been desensitized to exhaust noise by my Mustang and boat. I haven't noticed any annoying drone either.
Can't say I've noticed any mileage improvement yet, but thats due my foot being in a little deeper and a little longer just to hear that CTD sing.
