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.

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.

sounds about right. What can I say, I'm cheep

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.

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

Thats for sure. Had the SW on the Polo, it was not bad. little cutting on the passsenger side support bar.

Jeals on the Admiral. no problems, lots of room. perfect bends.

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.
