Easily one of the best turbo extensions on the market for the 240SX! This unit has a built-in diverter plate to seperate the wastegate discharge from the rest of the exhaust gas to combine the two further downstream. This reduces turbulence and improves exhaust flow.
Also includes an O2 adapter so you can use either the "Skinny" or "Fat" SR o2 Sensor. New mounting hardware is included as well.
(NOTE: For S15 turbo users, there is a small diverter already cast into the turbo housing, so trimming of the turbo elbows diverter plate may be required to fit.)
