The previous owner did all the mods...What modifications makes 390 rwkw?
If that result is authentic then it is likely the engine is tuned for top end, can’t have both without some deep thought and derp expertise. Else no thought, no expertise and plumb up a supercharger?
H-Pipe: Uses the Hemholtz resonator theory. The H pipe's ratio to the exhaust pipe will cancel out a particular frequency, when done properly it will reduce and in some cases, eliminate drone. The sound from an exhaust is more refined using the H pipe as you have each banks' pulses travelling for the most part independently from each other. On a V8, this gives you 4 pulses in each side. Sounds good.hey NAAF what effect will it have changing to an H layout on the exhaust instead of X merge, was thinking about putting a thread up about the merge/x pipe/h pipe what effect it would have on flow/sound etc
