I recently picked up a 01 with a built motor and extra goodies in need of some TLC. After doing some research and talking to previous owners i found out from Jeff Evans that this was one of Full-Race very first manifolds ever built. It got me thinking that maybe i should look to upgrade to a Twinscroll setup. So id like to hear from some Twinscroll guys and also guys running newer prostreet manifolds. Besides the placement of the wastegate is there much difference in the old style prostreet and the newer style?

 

well besides the wastegate position, the turbo it up front with the wastegates now, the prostreet manifold is no slouch and is def one of the bast manifolds out there
