i think two pipes that are 2.5" flow more then one 3" pipe.

3" pipe has 7 square inches of area and two 2.5" pipes have 9.8 square inches of area <4.9 each>

 

True, but what if you run 2, 3" duals like I did..lol.

I built my own as well. Bought the mandrel pieces I needed, mig'd it up...bough the mufflers/resonator.

I don't have but a few hundred in it all.

 

well in that case, you have the numerical equivelent of an assload of flow!

 

I think it really depends more on the quality at the transfer from 3" to the 2 smaller dual outlets. In other words if the 2 outlets connecting to the 3" pipe are crappy in terms of ID" and how they connected/welded them, then you'll be restricted because of that...

 

The Asura Design 3" Dual exhaust is made from mandrel bent 304 stainless steel polished to a mirror finish.

Our system is 3" from the catalyst back and incorporates with the OEM flanges on the factory catalyst. The resonated mid-pipe transitions to two 2.5" pipes to each of the oval mufflers. Tip options are both round for the AP1/AP2 bumpers and hand shaped and finished oval tips for the AP2 bumper.

All gaskets and hardware are included. We also offer 3" High Flow Cats and 3" Resonated Test-pipes.

There is also a 70mm (2.75") dual system now available in addition to having 2 mid-pipe resonator options (63mm) 2.5" and 3".

 

I had my tuner cut off the flange on my Invidia duals, and V-band them so I could keep it with my turbo!

 

We can offer a 3" V-band flange welded where the cat flange would be.

asura, any more pics from farther back to see how the cans sit on an ap2? they look like magnaflow mufflers to me..

 

Asura's got my vote. I don't have one, but from what I've read Asura makes one nasty exhaust.

 

Now you tell me
