Lately I've been considering putting my Legend on the bottle. My only concern is this: My friends and others have told me all kinds of things about how NOS like corrodes your heads and pistons. They have told me that most engines can't handle it, especially one with over 100K miles like mine. But I'm not sure if this is all true or it's just people naysaying because they don't have it. I know one thing, if I had NOS I'd be leaving all their asses in the dust (even though I already do, most of em anyway)! So anyway, can anybody with knowledge on the subject speculate? Should I get it or not? Any input (especially from folks who have NOS) would be greatly appreciated.
