I bought this setup new from JPC in 2011. Installed it on my car, sold car in 2015 with 10k miles always garaged. Not sure the version, but headers are 1-3/4", high flow x-pipe, O.A pipes are 2-3/4", mated to JPC mufflers with 4" tip. All stainless steel, awesome condition except I stepped on one of the mufflers while trying to get pictures(you can see it in the picture). 1400 obo, need them gone, tired of them sitting in my garage. I'm located in Bakersfield, CA. 6619009306
