Borla makes headers?
I had no idea borla made a header for the NAs. I don't even have an NA anymore, but found it interesting. A little expensive though.

OMG!
Damn if that is true from just the header we may have just found something that out performs the Duals with the addition of a silencer and free flow cat-back.
Someone buy one of these bitches QUICK I want to see the dyno proof!

Sweet fancy Moses that's expensive. Does that million mile warranty include rust?
25hp is a lofty claim, I don't see how their header design can be much different from what's already out there, it's not like a V8 or something where there's lots of ways to tune the pipes, our headers are pretty straightforward. I don't think we'll ever be seeing a dyno sheet at that price.

Claims like that I assume would be using their full exhaust set-up, as seems to be the market standard when advertising.

Pipe dia. is just relative to the size of the exhaust port, collector positioning is just a convergence at the same length. There's only two pipes to deal with here so power pulses etc. that you'd get with a V8 and 4 pipes you have to tune by length, the complications that occur only marginally apply to the 13b.

Not kidding at all. The RB header is a "suit-everyone" header. Its designed to keep a powerband in the mid-range, for generaly streetability. IMO, RB stuff is over-rated.
Collector position and diameter has a huge effect on powerband. Denying this really has me questioning your knowledge of fluids... Would you like the explanation?
While I do not deny that building a tuned header for a V8 or 4-banger is more complicated, I stand by my point that powerband is affected by header design on a rotary.

well it may be 900 bucks but atleast someone else is making quality parts for n/a rx7's, i say the more the better. ill stick with my newer style pacesetter though, im totally happy with it, but i need to fix my exhaust leak...its as loud as a damn motorcycle but a motorcycle on meth

haha...its not on anymore...my dad has my gtect so i could never run any before/after stuff...im pretty sure it worked seemed to give it more low end torque...but im not certian cuz i put the headers on at the same time. hey it was worth a try but in retrospec i should of just spent the money on weed, beer, or strippers...would of been worth more
