I bought the manifold used from and EVOM member on this board. The primary tubes are the exact same size and both manifold are equal length.
1.00 too small?? I'm not sure yet..the only facts that stick in my head are those who switch to the T4TS from a T3 picked up 500 Plus RPM on spool up. Meaning one of two thing. That the 1.06 (6% bigger) is flowing like 30% better then my 1.00. Or it is a restrictive design causing back pressure and faster spool?? So far my back to back hardware test showed gains across the board, with only a 100-200 rpm pick up in spool. This is just data to throw out there.. Hopefully soon I will hit the dyno with 35 plus psi to see what happens.

Driving around town is very smooth.. you can feel the car has a little more pep at low rpms. The throttle feels a tiny bit more responsive. The best part is the exhaust actually sounds different. I never thought the back housing would give it a deeper sound.. Less ricer like .. LOL
