hey guys.. i'm taking my Invidia exhaust off today. My stock exhaust has been sitting out in my backyard for about 3 months, its been rained on and all sorts of stuff.. is there anything i should do to it besides cleaning it on the outside before it goes back on the s2k. btw i notices some rust on it as well.

thanks

 

It's not a stock exhaust but an aftermarket exhaust and it has steps.
