The headers i got for like $100 from eBay, then the slipon ran me around $300 new, wasn't able to find anything used, as far as the fairing I used my Dremel and notched it out, also notched the fairing around the headers, because they dip a little lower, just spent 13 months in Afghanistan so it's all presents to me!!
No kidding 13 months I thought they dropped deployments to nine. Anyway $400 for basically a full titanium exhaust set up not bad. I've been thinking about doing the same exact set up myself, hadn't decided on hot bods or m4 though, but I'm hesitant to drop anymore money into this bike. I've put way too much into it as is
