That guy was a total pain in the ass… I tried to buy a number of things from him when he first posted it all up and couldn’t get any details on his stuff. It was like pulling teeth. So I got pissed off at him and gave up. Then he posted a set of Milltek Catless dp for $300 and I couldn’t pass them up so I pretty much sent him the money on blind faith. They turned out to be in pretty decent shape and I’m quite happy with them for the price.
The nitrous kit is the one that Jdubya was selling a few months back. It has been used and I’m sure was sold to him in good shape. Who knows about the condition of it now… I can tell you that JDudya had it posted at $2200 and it sat for a while. My guess would be that he paid no more than $2000 for it, so he’s trying to make a few bucks.
The JHM IM is over priced as well in my opinion. I bought mine used from Jdubya for $500 plus my stocker. That was probably on the low side so $600 plus stock might be a realistic price.
Overall, that kid is extremely immature and hard to deal with so be very careful if you buy from him. Meeting up locally (if possible) would probably be your best bet to make sure you get what you’re expecting.
