    i am building a Z6, nothin fancy just port and polish head and intake mani and port matching them. balanceing the stock bottom end. Bored .020 over to clean up cyl walls.
    i have an Ebay chrome header that is 2" on the collector.
    for a muffler i'm getting the flowmaster axle back. its a 2" pipe also.
    i know 2" all the way seems logical but i don't want to loose all my back pressure.

    this is all going in an 88 civic DX and the stock pipeing is like 1.6" i think
    thx

    2" is fine for a lightly built Z6. I wouldn't dwell to much on backpressure.
