I purchased the very last one of the version 1 j-pipes about 1.5 years ago, and I am extremely happy with it. So if the version 2 will be better, you guys will love it. Just my two cents.
Side note, I purchased it through Jason Burtman, among a ton of other things. One particular part (not from RV6), that I purchased through Burtman I had to return. I returned the part, never received my money back. He has been dodging my calls for over a year now, and owes me money.
All i am trying to say is do not purchase anything through Burtman, if he is even still in business. Just my other two cents.
