I had been contemplating polishing my Termi full system exhaust. I am a huge fan of Staintune exhaust system and have had several of their systems over the past years. My 2003 Blackbird sports Staintune slip-ons. Staintune is the standard I use for judging aesthetic appeal of an exhaust system.  

I really like the satin finish of the Termi exhaust canister and hanger assembly. I did do a bit of hand work with ultra-fine "Scotch-Brite" like material, mostly to brighten up the welds. I didn't think grinding down the welded joints was such a great idea and once I brightened them up and removed the discoloration on the welds and adjacent areas they look great. I wanted to polish just the pipes and 2 into 1 coupler so that they would turn a beautiful shade of gold as they were heated and leave the rest of the system with its nice satin finish.......

I took the easy route and had the folks down the block from me at the plating shop do the polishing. Staintune could NOT have done a better job. 

I actually have a pro buffer setup with the correct wheels and polishes for Stainless Steel but I am getting lazy these days. BTW a great source for polishing equipment and instructions is Caswell Plating. http://www.caswellplating.com/index.html

I have done a fair job with their equipment on other projects, mostly aluminum. What is very important in buffing metals is have the right wheel speed, the right wheel and the right buffing compound(s). Caswell has all this information on their web site. Check out their 1/3 hp buffer kit for only $108.90!!!!! as to 01/28/2006
