That is "what has been said" however the simple truth is no one ever dyno proved any difference between the two. Matter of fact there are 2 rather low dynos with folks using SHM headers. (there are few dynos with SHM's btw)
You are probably right, but I do seem to remember a guy that put down ~190 hp in (I believe) a 2000 2.5L CSVT with SHM headers (among other things). I can't remember his name, but it was the last dyno I saw of anyone with the SHM headers. Also I know, it's only one guy, but I still would like to find that dyno graph of his.

You know you launch hard when you beat oncoming traffic through their own crosswalk lines.
