I got a set of torque tubes and a monster exhaust a few weeks ago directly from Banks. The ones in the quadratech picture are painted, or coated. Your right...they should show a picture of what they put in the box. It is 400 series stainless tubing that is heat resistant...it looks decent but not at all like the pic.
Be care-full if you decide to paint it, or coat em...the 400 series stainless is designed to release heat and coating it prevents that somewhat. Header wrap will usually void most warranty's too. It still looks better than the stock one to me...and not ugly at all...for an engine part.
The monster exhaust muffler is polished stainless and looks like a mirror bright chrome finish. That is until you scratch it on the first rock you climb!
Bottom line is Banks is one of the best, great headers and an awesome exhaust! When will they make the Ram- Air cold air intake system for the 2.5?!
