OK im NOT starting a debate weather or not dump valve or chatter is the better sounding...just want to know what kind of dump valves people like to have that sound and perform nice....atm i have a le mans which not only sounds bloody shite but i think it has a leak

....
so what is the best soundin?? and what is the best performing??
1 person said to me baileys is the best one...but had no reason..
cheers
p.s. would be great if anyone had any sound clips or video clips of a rs turbo with some nice sounding exhausts and bovs...
