General Bike Ravings

As some of you know, I have a set of ARROWS pipes on my R1. I have replaced the pipes from the Cat converter back. On Tues, I am going to have some of the packing taken out the pipes to give me some much wanted nice noises'. (I hope) The stock pipes were almost as quiet as a Goldwing and the ARROWS have given me a bit more decibels (and a tiny wee bit more BHP) but it still not as loud as some other branded pipes..... why ARROWS? Cause I got them at a good price, so had no choice which brand. ...
