My exhaust tips on the aurora were previously rust colored, and some parts were still covered in factory black paint covering the tips. Since the entire exhaust system is stainless steel I figured why not sand down the tips and shine em' up after seeing a post of somebody else doing the same thing on the Aurora board. Basically first you have to start off with 80 grit sand paper and remove all rust and paint until you get bare metal. Then you need to go to 120 grit to 220,300,400,600,800,1000,1500,2000. Here are a few pictures of the progress. Sometimes I swtich from one tip to the other in the pictures because I didn't get pictures of each individual tip on each individual stage.
Before any work:
some rust removed:
All paint/rust removed. a wire sanding bit for a drill works GREAT for this!
this is the tip at stage 1000 Grit of the sanding:
after the 2000 grit and polished applied. I couldnt' get a good picture of this stage for some reason. camera was acting up. :(
I hope that this is useful for someone! It sure is a GREAT cosmetic mod!
