Ultimate Racing Catted Downpipe | 2017-2021 Honda Civic Type-R FK8 (30010-CAT)

2017-2021 Honda Civic Type-R FK8 Catted Downpipe by Ultimate Racing

Ultimate Racing's downpipe design is 3.5 coming out of the turbo and continues to a true 3 tube, even at the connection to the stock CBE flange (unlike other brands that will reduce the tube size just to meet the OEM flange).

The Civic Type R FK8 has a very well designed and tight fitting under cover for aerodynamics. This means not much airflow can enter the underside of the engine bay to cool the DP during WOT pulls. The result is increased oil and water temps as the hot unwrapped DP heat soaks all components around it. Wrapping the DP will keep the heat in and prevent the DP from radiating heat to the surrounding components.

Ultimate Racing has a mechanical fix for a CEL after this is installed but it is NOT a permanent fix, just a prevention. The O2 extender option will make it less likely to get a check engine light, however the permanent fix is to have your tuner disable it in the tune.

To fit this downpipe to the stock 2" flange, Ultimate Racing supplies a special gasket and hardware to make the connection work. At a later date when you are ready to get a 3 CBE, the result will be a complete, TRUE 3 exhaust system from turbo flange to muffler tip. (Other brands will advertise 3 but you will find reduced pipe diameters when meeting at the flanges as this is easier for manufacturing.)
