bridgeport exhaust
s4 tii bridgeport engine with n/a rotors and 60-1 t04 turbo. I have a 3in dowpipe which deletes the two precats and a borla muffler in place of the main cat. After that muffler the piping goes to the stock size 2.5? to the magnaflow muffler. Would that cause alot of flow problems? Reason im asking is becuase the power is kindof low for a bridgeport and only gets to maybe 10psi with a boost controller and 10lb spring. Doesn't seem like the wastegate is opening either.

i have a 3 1/2 turbo back on mine with a NI single exit exhaust running a 62-1 with a 1.15(NA rotors),boost starts to build up around 2200 rpms and it holds 15 psi steady all the way to redline and if stays there if i dont get of the gas,if i stay on the gas it keeps building boost,i love it.

you have all sorts of choke points in the exhaust system. 3" downpipe to a 2.5" catback, small divided turbine housing to an undivided manifold... be careful though, the HKS manifold is prone to boost creep. if you open the exhaust enough you may have some problems unless you have a large wastegate (the HKS 40mm will definitely creep at 10psi, it did on my streetport).
