ive got to go for a blue slip inspection and currently have vance and hines big radius 2-2 theyre quite loud as some people may already know and i have a feeling ill be pulled up on them when i go for my blue slip, i can borrow a softail standard exhaust however i dont know whether or not it will bolt upto my bike? its a 2013 model if that helps. im in sydney so if you know anyone who isnt as strict about exhausts when it comes to blue slips that would be even easier. cheers

Is that a Fatboy ? If so , then the complete exhaust system is "unique" to that model line.

A Softail Standard system will fit , bit you'll need 100% of it, frame brackets, balance pipe/bracket and all.

Also the system will have to be 2011 or younger to have the O2 sensors of the correct size in the correct place !
