Its a real MSM. I bought my car from him, this is what he replaced it with since the 99 was "too slow". To be honest I wouldnt recommend buying it. He's young, buys cars, drives the shit out of them and then sells them when he's bored. This one had a big turbo kit which is the reason for the larger front mount. According to a friend of his that I know it was nearing 300ish whp.
I didn't confront him about my car but basically he didn't fill me in on all the details about it, I found out later on but that's my own fault for not looking into it. Car was a Cali car, 6 owners, he bought it from an auction for less than half of what I paid. Never transferred the title over to his name so I had to go with a bonded title. After gave him the cash, he told me about the EGR issue. A couple of thousand miles later; piston ring goes.
