I got the exact same pipes. They are awesome pipes and will outperform toomey's, fmf's, pro circuits etc.... I ran mine on a 421 cub. Trinity's customer service is kinda shitty tho. A lot of flat track racers like trinity's. You may not get $500 for a set of used pipes in this economy though, thats the only crappy part about the deal. I bought mine for $350 and they looked exactly like yours and I had the engraved silencers as well. Good luck with the sell bud, I can vouch for the performance of these pipes.
