Is the DP true 3” throughout, even at the connection to the catback flange? A. YES, our 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). Q. Why does UR suggest full heat wrapping for this DP? A. 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. Q. Will I get a check engine light with a Metal Substrate Converter DP? A. We have a mechanical fix for this, but it is NOT a permanent fix, just a prevention. Our 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. Q. Why should I get the DP with a High Flow Converter? A. For maximum power gai
