For only $140 it seems to me as a "no brainer". As far as the loud noise that you get from some BV's I am fine with nothing louder than stock. I guess you get to a point where "sounding cool" is not a buying feature but something of more one's personal taste. Where as myself if it does not improve the performance of the vehicle than it would not interest me.
So I take it you would agree with my choice of the GFB DV as a replacement for my failing factory unit?
Many Thanks,
David
I have it, it's the perfect replacement for the stock unit. Doesn't make any extra noise from what I can tell. Have had it for over a year now.

just ordered the gfb dv+, regarding install any ideas how many hours a indy shop would charge? Im thinking 2 max? DIY looks possible with right extensions, I would rent a lift $20hr if I were to tackle myself.
