XT 500 Wheelie Pipes

Bought a set of new pipes for the xt500 to try and get ride of the huge stock pipes.  Definately will shed about 10-15lbs off the bike..  The pipes look great!  Stainless tig welded pipes.  Putting them on is a different story... I can get the head pipe on but the rest of the exhaust fits like dog shit.  Trying to figure out what happened... I should have just made my own set, but i wanted to get this thing on the road for the winter so i splurged and got a set... mistake. 

Anyways... contacting the company to see what to do... in the meantime i think im gonna but a headpipe off fleabay and make a set myself... *sigh*.
