Welcome to SG ownership. I have been thinking about slip-ons myself and have been told the Vance and Hines ovals are nice. A friend has some on his '07 SG and they sound good. Not to loud, but nice rumble.

 

had wild pigs on my last ride they are good for the price got a set of blemishes for 160 couldnt find the blem. one good thing about them the baffles are affordable so changing sizes isnt going to bankrupt you 1 3/4 was plenty loud for me.got jackpots on the new ride and very happy i got the dynotuned baffles however they will set u up with whatever baffle u want.

 

screamin eagle good sound and performance.

 

+1 on the BUB 7's. I love mine.
