Default Prova (replica) Headers: New or old?

Hey all. I was just being unproductive at work, surfing the rs25.com forums, and I found this product in their "Vendor" forum.

Clicky

The vendor stated that these are Prova headers, which he explains were made for the Legacy awhile ago. Has anyone seen these before? It's made me very curious...

He goes on to explain that the Borla header system was made to be a Prova replica. Can anyone confirm this? Are these headers that I've linked to different from the Borlas in any way, other than price?

I think they are new, and I'm not a huge fan of the design. My feeling the biggest problem with our exhust design is it's path. They wrap around, and form a sharp angle to go into the cat. Just doestn' look as thought they improve flow enough.

seems like it might be better to go with a set of these and save some cash, but you wont get the million mile warenty

But they will look nice for about a week before you trash them up...

also, I doubt they have the same R&D put into them. anyone can copy a shape. Borla has taken many steps to stop cracking and whatnot. I bet these will crack quickly, or at least quicker. I'm remembering it took borla till like gen4 (they're on gen5 now right?) to eliminate the cracking problem.

Borla:



Prova:



structurally the borla looks stronger with the bracing section, and the collector also looks superior. I'm not biased either way since I'm too poor for either. I'm just looking at the designs.

Aaron - any flow design is better than stock . stock has 2 tight turns one after another just before the cat. either of these should eliminate that first turn. but then I think it's the opinion that Borla headers and clones do little for performance, and much more for sound.

That "bracing" is exactly what caused the cracking on the borlas and doesnt exist on the newest model borla headers. Being stainless steel and having what I see are stronger welds all around, the Prova should be better. The overall design is still kinda weak hp wise though...

Like I said, I don't know much about the designs, so I'm just going by what I see . I guess we'll have to wait till someone with a set of them shows up and lets us know how they are.

They will fit, all the N/A dual port EJ engines have the same header design. Only a select few 2.2l engines have the non-compatible single port design.
