My Marks system is now 3 years old and still looks and sounds great, albeit a bit louder.:biglaugh: I take the exhaust off yearly to clean up and polish during the winter downtime. I use Mothers metal polish and it takes about 3 hours worth of work so they.
My system is SS 4 into 2 w/ 12" 2.25" no endcap mufflers,
I happened upon your Youtube vid the other day. I was trolling around mindlessly picking off exhaust vids from the selection list. I started playing one and was thinking "man those sound wicked" and then the camera panned up and over the seat quickly capturing the infamous "redbone" lettering. I was like "Damn, it's Redbone's!"
