Re: OBX Headers?
Just checked my OBX. #1 is about 25" to the clamp, #3 is about 19" to the clamp. the rest were too hot to reach into.

Re: OBX Headers?
Clamp?
My measurements are taken beginning from the primary coming out of the flange, ending where the primary tube goes into the collector. I'm sure sure how the clamp could be over the collector so far that it's touching the primary tubes, but perhaps I don't fully understand how the OBX version connects to the cat/exhaust. If they are in fact the same length primaries, the photo I have is quite deceiving. They definitely *look* shorter.

Re: OBX Headers?
I got probly 19 or 20 if I just measure the tube. Do you think longer makes that much differance? I'm assuming longer means less interferance from cylinder to cylinder.

Re: OBX Headers?
Longer tubes better exhaust scavenging
Which makes more power. How much more? Very hard to say, maybe 10hp, perhaps less. Better still is Equal length tubes, but there were only two Sets of equal length LT5 headers made (by LPE). I know where one set is, it's hard to Believe the ridiculously twisted tubes fit Underneath the car, but they do. Brian A 90 ZR-1 ZR WON 12.09@118 01 Z06 Not quite stock |

Re: OBX Headers?
Well, I'll dyno my car in the near future. OBX headers, exhaust, and Marc chip. We'll see how that compares to the last dyno. -Steve

Re: OBX Headers?
ZR WON- Your SSW header picture is not what they currently show on their website - also they call out 304 SS construction

Re: OBX Headers?
Amazing
It would seem they did change the design. I have no Idea why they would do such a thing, but anything is Possible. I'll call them and see what they have to say. Al Noe, who was the General Manager when I was involved Is no longer there (he works at Trick Flow, I believe), so I'm not even sure who to talk to. Ron used to own SWs, I'll try Him. Yes, 304 stainless is the same as Jeals, Watsons were Made with 409. Brian A. 90 ZR-1 ZR WON 12.09@118 01 ZO6 Not quite stock |
