    Exhaust Make

    I was wondering if anyone knows what make this 4 into 1 is????

    The headpipe is wide in diameter 1 5/8 inches, the collector is centered under the motor.

    any help will be appreciated!

    Thanks,

    Marc

    might be a old yosh, they centered then under the oil pan. What diameter is the collector? 2.5" would be post 82 yosh pipe.

      That is a Bassani header.

        not a yosh, they usually have a longer collector and just doesn't look yosh. I don't know how to explain. the bends just don't look like yosh.

              Hi,
              Thank you all for the information.The O.D. of the collector is 3'', and the inner part of it (inside the outer collector) is 2 1/4''.If this header is a Bassani i will try to find a muffler for it.Or make my own???

                First make sure you can get all that rust off without making the wall too thin.

                  The whole thing look bad, but this is only surface rust.
