Was really wanting some lsr 2-1's for my bike,but after sending email to rbr asking for lead time .The response i got was a little short "when they're are ready" .So after checking around on other decent power makers ,seems like Bub 7's 2-1 are on the list.And the price isn't quite as high as a lot of the others,that most others have "heat shields extra".I think i'm reading shields are included on the Bubs??I have andrews 37 cams in an 88 but will soon be going to 95 with a little more compression.Anyone have comments (mainly performance ) on these on a mild build dresser
