    4 into 2 exhaust

    Im sure this has been asked thousands of times, but I'm hoping someone can help.
    I'm trying to find a 4 into 2 exhaust for my 1977 GS750. I have found some end cans (marvi?) but no down pipes.

    So here's the question(s):
    1. Anyone know of a supplier for a full 4 to 2 system for the above.
    2. Will GS1000 down pipes fit my 750.
    3. Anyone know of an alternative?

    For what it's worth I'm in the uk.
    Cheers

        Bump.

        Not having alot of joy here, surely with the expertise on the site (& model) someone can advise if the down pipes (headers) off a 1000 (or 850) will fit a 750?

              Pipes from an 850 should work fine.

              The pipes from a 1000 will fit, but the bolt spacing on the retainer collars is wider, so you will have to slot the holes.

                Perfect thank you. They seem to be a little easier to source (but
                Still very expensive)

                  See attached pipes for GS 750 E. Brought them from Tranzac in Brisbane Australia.

                    Very nice. I would love to know where to get oem looking pipes for my 1000.

                      Can you post a picture of them on the bike when you get there and an audio file of them, thanks.

                        Will put more pic up when installed and going. The company is at:

                        Come to Tranzac Exhausts and see our range of new and used motorbikes and scooters and motorcycle accessories in Carbrook, or book in for a quality service by our expert mechanics.


                        Note they are not original but very close.

                          Can we get new mufflers for a 4 in2 anywhere in Canada or the US?? Seems next to impossible. I guess thats way so many folks switch to the 4 in 1. Kind of sucks as my pipes from the head are really nice. My baffles rotted out from my exhaust.

                              I saw those eBay ones, 400$ shipped to Canada! Ouch!!
                              It sucks as my pipes still look good, the baffles just rotted out. I wish I oculd buy just some baffles that slip in.
