I sold my Warpspeed Y-pipe to nupemaxima.
Overall, it was a very smooth transaction. I listed my price, he accepted it, and asked to arrange to buy it immediately(the same day I posted it i think).
He did not try to lowball the price, or delay anything at all.
I received payment for the exact amount i asked quickly and without question.
He was very understanding that it would be a couple of days after i received payment before i could ship the y-pipe to him, due to my work schedule.

I would definately recommend, and sell to nupemaxima again, A+.
