Hey convincor: Did you change your headers too, or just the pipes?
They look (and sound) great.
I know a guy that went to SS pipes on his SPF (versus the standard SPF pipes) and they were definately louder. But I was under the impression that the change in sound was due more to the larger (less restrictive) openings in the pipes (versus the SPF pipes) than it was due to the material that they were made out of.
