Y Pipes make them sound so much nicer, was the first thing my mate did to his one when he got it a few years back.
I've driven Alcon and RS29 bloody amazing, but too much for road car and dust level is horrendous. But brake power wise absolutely insane, they are generally quiet too as long as you use them once or twice a week to their ability.
I love XP10 and XP8 combo, so much power, no cold bite issue and completely silent, only issue is huge amounts of dust.
