All the glory, none of the flaws. Part of the Sound Performance Signature Series Product Line. SP Racing F1 manifold and F1 Turbo kit for the 93-98 MKIV Supra, collaborating with Powerhouse Racing Billet collector. Loosely based on the original RPS manifold, which was unmistakably known for the distinct exhaust note it produced, the new F1 manifold takes a new perspective on a classic design. Harmoniously balanced, the F1 manifold produces a highly unique smooth sometimes raspy exhaust note that sets it apart from alternatives. This alluring exhaust note is sometimes referred to as sounding similar to an F1 car. In addition to the exotic exhaust note, a number of additional improvements have been implemented into the new design to offer the highest quality product possible at an affordable price. Throughout the duration of the F1 project and our research, we have found that the original RPS manifold exhaust note is not always consistent and depends greatly on the rest of the supporting modifications. Cat-back exhaust choice, cam selection, port work, and oversized valves all influence the exhaust profile of a vehicle and can alter the sound produced either slightly or dramatically as a result. We have witnessed the manifold produce both a smooth exotic tone and a rumbly deep tone simply from different supporting mods. It should be noted that your vehicle may not sound exactly as the sample sound clips provided by Sound Performance based on this information.
