yeah just like the under manifold hose makes no difference.

i have run headers too and i have run without them.

basically take your motor and look at it like this.

NA + Turbo

the NA side of your motor will give you many good lovins for getting headers.

The turbo side of your split personality will say where the hell did my pressure go ?

fact of the matter is. if you increase flow through diameter changes. you loose pressure. if you change the material you change the heat scavenging effect. so youre screwing yourself twice. even if you coat the headers AND wrap them, you cant get it all back. however. im not saying the loss to gain is 1:1 ratio.

there maybe 15 negative side effects and 1 positive effect. doesnt mean its an overall negative mod.

you find one thread on the internet or one person saying one thing. ill find 10 others that say the opposite. and noone knows anymore who is credible.

when i moderated a sportbike site we caught one of our vendors registering fake names and saying duragatory things about other vendor's products. also he would say how good his own products were.

needless to say. do what you want! its nice to have imput. just keep in mind who is credible and who is not. <3
