I would imagine the surface rust is due to it being a lower quality stainless. Not sure what type. I know several exhaust products I've had over the years gather some surface rust. Even the 409 stainless and aluminized types. The tip and muffler are a polished stainless that seem to hold up nice. It wasn't too loud. It's just that I tow an enclosed trailer once in a while, and prefer the extra bottom end torque of a factory system.
this system does have the 70mph / 2,000 rpm drone ... was the same system I had and sold it cause I couldnt stand driving long distance without getting a head ache ...... I got better gas mileage with the magna flow 15862 when I went with the 35" tires then I do with the stock exhaust. $200 shipped is a pretty good price considering it is over $400 to buy new
Hey Ramtough, get bigger tires like 35" all terrains and then put this exhaust on, you will notice alot of power compared to the stock exhaust and since running bigger tires when you are 70 you will be less at 2000 rpm's and the cabin drone wont be as bad as with stock tires.
