Flowmaster 10-series 1-chambers

I'm wanting to quieten it down a bit and get some GT500s. These are 9 months old. We just cut off the stock mufflers at the case, welded these on, and made a short extension pipe for the tips. Will bolt on, no trip to the muffler shop. $200+shipping. OBO

Not sure why it's showing up Flow +master in the title...

Here are 2 videos from right after I put them on:
