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.May trigger CEL.For maximum power gain, catless is the way to go. Utilizing their Metal Substrate Converter with the stock turbo they see a 2-3% power difference compared to catless. The big benefit they feel is not having to deal with the raw exhaust fumes when the car is at idle or while waiting during a stop light.The catless version DP is 100% 304 Stainless Steel (unlike others that may advertise as stainless but use a lower grade of 409 SS).To fit this downpipe to the stock 2" flange, Ultimate Racing supplies a special gasket and hardware to make the connection work.FeaturesWith NO tune, gain of 10WHP & 15 WTQ.
