Flows much better than the stock part increasing HP and reducing possible KR.  Will fit your GXP or Redline kappa chassis car.

Since it is a non-gasketed fit up from the turbo outlet to the downpipe, we recommend mating these two surfaces with a bead of RTV Ultra Copper Gasket Maker.

Our downpipes come with a high flow catalytic converter that is 48 state legal. Our catalytic converters will not pass California or New York state emissions. Please contact customerservice@zzperformance.com if you have any questions.
