What Post-2005 Parts Will Fit Pre-2005 Bonnies?

Greetings. I'm new here. My name is Tim and I'm in northern California, USA. I've been riding for 30 years but mostly Japanese bikes. I've been looking for a 2012 Street Twin but have an opportunity to buy a 2003 T100. I love the blue and white paint (like on the 2012 ST) but I much prefer the upswept pipes of the ST. Or are there aftermarket pipes for this T100 that resemble the ST pipes? I'm also curious if the alloy wheels from the later models will fit an '03. The wire wheels are beautiful, but tubes...

 

CORRECTION: I wrote "Street Twin" when I meant to say "Special Edition".
