Have you considered doing a flowmaster merge, with a 4" muffler right after it. I wonder how much weight you would save compared to a true dual exhaust. It seems to work well on KP's car.

Yea those are some good RWHP numbers on a single 3in...
And speaking of "surface area" I saw this in another thread that may apply to this...

For comparison, let me give you rough cross sectional area, which indicates maximum flow:
single 3" - 7 square inches
single 3.5" - 9.62 sq in
dual 2.5" - 9.8 sq in
single 4" - 12.5 sq in
dual 3" - 14.1 sq in

well I can tell you my buddy's d1 setup is using mac mid length headers, with their Y, some high flow cats, and single I pipe back to the borla. I think it is all 2.75" could be 3" (whatever the borla exhaust comes with) and he makes 650+rwhp seeing 12psi on the boost gauge. I don't think your exhaust is hurting you one bit, and if you change it the only thing flowing better is money out of your wallet.
