holy butt plate

[cosmo_bojinski@hotmail.com]

Hi List,Tweety has finally arrived in full force on my A12(9500Km).The last couple of weeks the whistle would disappear after it warmed up but now it wont go away.Previously I had considered doing the Swiss Cheese Butt plate just to improve exhaust tone but chickened out at the thought of ruining a legal spark arresting stainless steel muffler well now it's starting to look like a good option.I'd love to hear from members of the drill team with pros and cons. Did it eliminate Tweety or is it just a temporary mask?Thanks.....cosmo and tweety
