Got the quiet baffles installed the other day. They're still loud, butnoticably quieter, especially at lower revs. Got 103 RWHP at the dyno, would maybe have gotten a few more ponies with the standard baffles, but I guess I got more power lower down. So overall I can recommend them.
I would consider only drag pipes or pipes with baffles removed to be offensive, IMHO the rumble you get from V&H baffles sounds better than no baffles.
