Full stock exhaust - how much?
 

So i've just upgraded to Fmf powercore 4 and fmf megabomb and now the stock header and slip on are just sitting on the shelf. I'd like to sell them but i'm not too sure how much it could go for.. They have about 1000 KM on them and no dents. If anybody could lead me in the right direction that'd be great, thanks

Try a search on Ebay and check completed listings to get an Idea or just offer them on here at best offer.

probably between zero dollars and whatever scrap metal prices are in your area, to be brutally honest.

Save it. Wrap it up and store it somewhere, put it back on your bike if you ever sell it, then sell the FMF system to recoup some of your investment.

You never get much back from a mod if you leave it on when you sell the bike.

One head pipe on ebay for months at $45 I've been following, since I have an extra. (I got it understanding it was a 300 pipe with my Pro Circuit slip on.)

Keep yours then if/when you sell your bike put it back on and offer the aftermarket set up as an extra, since so many buyers seem to think aftermarket parts aren't worth anything over stock. If it doesn't go with the bike sell it off in the forum or on ebay.
