So I was on RPW, and was checkin out there style header, seen they made 41, and 44mm header piping. I was courious if NE one on here had the specs for the ROAD RACE MOTORSPORTS header. thanks to all that post...

 

don't quote me but there's is 44mm. i know adamRA picked up the RPW 41mm b/c he wanted it smaller then RRM for the better torque gains.

 

oops

 

Wrong I have the 44mm

 

...ok maybe it was ralliart50 then??? lol sorry. hes running an auto right?

 

Now you got it..

 

one day ill invest in a brain....

 

i going to fabricate a headerI think I am going to go with Adam and get the smaller piping for better torque

 

I've got the 44mm 4-1 RPW Headers. Top product!

Adam, did your CEL light up? If so, how did you get rid of it?

 

lol! Yeah, I'm running the 41mm because I have an auto and wanted more low end torque. It definitely makes highway passing a lot easier!

 

Go to this post and try it.

I went and bought some anti foulers but I haven't had a chance to try them yet. I'm hoping to get them in this weekend or sometime next week but we'll see how my schedule works out. I'll let you know if it works when I get them in.

EDIT: Oh, just in case you can't find what size anti foulers you need they are 18mm.

 

We answer the phone on U.S. time. Ask us. WE have headers in stock too. Ask for Rob or Gabe.

U.S Time? I think what you meant was PST ( Pacific Standard Time)

 

I knew someone would get that but what I did not say was that we are not on another continent like some other header guys. Golly I hope I don't get in trouble for saying other header manufacturers on on another continent.......

I have the RRM Header and measured it at 42mm. great hp for sure. I wouldn't trade it for anything.....well, for their turbo i would!
