The ARHs new sound is described as having a much smoother and more refined exhaust note, with the typical S54 rasp practically eliminated! Another description was that of a Supra engine just rolling into boost but before the turbo(s) are fully spooled. A sound slightly higher in pitch and significantly more refined but with no rasp. The 6-1 merge with primaries sequenced for rotational firing and the single outlet 3-1/2”downpipe leading to the secondary section are responsible for this new sound. The collector allows the air to merge smoothly instead of turbulently in traditional collectors. For a system designed to make the most power humanly possible from this motor, the sound is very pleasant and the drone is minimal, but drone is ultimately controlled by the muffler you choose (so choose wisely).
Headers are made in the USA of all 304 stainless steel.
