Bruce fab is a new guy on the market. As far The pipes go they could use a little more specific desighn. Its just a right and left and he tries to make them so that one set will fit multiple bikes which gave me mounting problems. But im a resourceful MF and i got them mounted with no aesthetic/functional probs. They might be feeble run of the mill mods to some but. Im one of the first with those pipes.
They give a throtey growl but arent as LOUD as they look. They can definately be heard screaming on a silent night if you know what i mean. A guy around the corner from me has a full muzzys 4 into 1 with full length pipe and his is louder than mine.
