The Peashooter internal straight through tube can be just perforated or can have forward scoops or louvres. The ones with the forward scoops are quieter than the plain perforated versions as the scoops pull more air into the outer chamber before it returns into the main flow at the end. They can also come with mutes but best avoided. Balance pipes will reduce the noise too but come with other issues. So go Peashooters, no mutes, scoops on inner tube and normal downpipes.
