I noticed many here still has the factory exhaust. I'm talking about the GT exhaust. It is possible to polish it with sand paper and then a polishing agent. Mine is polished now, and many think it isn't stock almost like a greddy. It looks good, though I would like to polish it more. It looks much nicer from the rear view now and actually the exhaust looks bigger now. Well, just wanted to see if anyone has thought of this like me.

best and probably easiest way is to unbolt the exhaust. buy some aircraft remover. spray it on (follow directions). scorch it down well, do soe wetsanding and you should be able to polish it with a good polishing agent...an abrasive metal polish
