I bought a O/R X pipe used form a member of svtperformance.com. I was told it was a magnaflow but it is aluminized and it is a 2 piece pipe. Magnaflow only makes stainless, right? and its 1 piece, right? I was then guessing that its a UPR( thats how i listed it in my sig). If i could figure out how to post a pic i would but if anyone knows who makes 2 piece aluminized x pipes let me know, Oh yeah its getting installed today!
