I don't see why everyone is complaining about $900 being too much. I think that seems like a very fair price considering used stock TT piping runs around $400 for a complete set from an individual, and z1 sells used stock piping for $650-$700 iirc. I'm going to start saving up for this as soon as I get my injectors and a few other misc odds and ends that I need for my car. Looks great, keep up the good work Ash!
