M-TH 9A-11:30/12:30-5P | F-SU CLOSED
This exhaust can only be installed with the 3.5" V-band downpipe.
Fits:
2007-2013 Mazdaspeed 3 Hatch
2007-2013 Mazda 3 MPS
Tuning: With the larger 3.5" piping we have found that some IWG (and possibly some EWG setups) will not be able to control boost as well due to the improved flow.
OEM K04 = Possible Mild Boost Spike
CST4 IWG = Possible Boost Creep to ~24psi (auxiliary fueling PI or methanol required)
CST4 EWG = Good (no spike or creep) (CS Manifold and EWG Turbine Housing Tested)
CST5 IWG/EWG = Good (no spike or creep) (CS Manifold and EWG Turbine Housing Tested)
CST6 EWG = Good (no spike or creep) (CS Manifold and EWG Turbine Housing Tested)
ATP Turbo = Not Tested
BNR Turbo = Not Tested
