Well dammit this is gay



I bought an RB header a while ago under the assumption that it was the best there is..



I gotta get an SDJ one now!

Hmmm. Those things look really nice. I don't want to call them and find out a price, cause I won't order it anytime soon. What would be the price for the 13b Street header? Does anybody know? And is there some kind of dyno sheet with the trq and hp #'s? I will probably go with the SDJ header if the price is right. I know it will be alot more than the RB header, just curious.



But on the street header from SDJ, there is a really big curve on the rear rotor exhaust hole. Is this really restrictive on the flow, or would it not really matter?

You want a header that works and makes power or one that makes noise?
Ur rotten pineapple experience isn't like the one I had with my own port job / rebuild + the RB collected header.



Pre header Gtech 1/4 mile time: 15.6



Post header (welded extension in place to bolt it to stock cat) : 14.9



Don't try to tell me it was the weather or driver skill; both those times were very consistent. The Gtech numbers held at a real dragstrip where the car, with the header, ran 14.9@95.



The RB collected header, when used with my stock exhaust on a street ported motor with ported intake manifold and cold air intake gave me seven tenths of a second reduction in my quarter mile time, with the _stock_ exhaust behind it.



Ur rotten pineapple had problems far beyond ur perception of the RB header being a bad product.

Just how much of that do you think had to do with removing some/all of the old stock cats as opposed to *just* the headers themselves?
