is the tip clear coated? If its actually stainless (sometimes they are chrome while the rest of stainless) and there is no clear coat you can do all sorts of stuff, how bad are the scratches?
You can try normal good quality metal polish and do a good many coats.
If its the OEM exhaust tip its stainless and not shinny so you can use metal polish and it should help.
You can use sand paper starding at 200 gritt then stepping up verly slowly 300, 400, 600, 700, 800, 900, 1000, 1200, 1500, 2000, then hand polish it or use a buffer. That will get you a mirror shine~ but its a lot of work. Just make SURE Its not coated with clear or something and its bare metal (AND polishable)
