  • Honda CB750 4 into 2 vs 4 into 1 Exhaust Sound comparison. This is a shorter video from the previous exhaust install episode I did that is just for the sound comparison. This is an unknown header I scored from a friend to fit my 1975 CB750 to replace the existing 4 into 2 setup. The muffler is a cheap shorty stainless reverse cone that you would find on amazon. The quality is meh but worth the low price.
    The full exhaust install video is here: • CB750 4 Into 1 Exhaust...
    For those unaware this bike came from a barn and sat with its engine seized for probably 40 years before I got it. Full playlist of bringing this bike back to life is here: • Barn Find Honda CB750 ...

    No choice for me, the 4-1 is the ticket. Sound is a HUGE part of riding, that is the sound for me. The asymmetry look I also like. Great scooter, one of the best!

      That is definitely not a scooter, that is a honda motorcycle with a hondamatic . So what's a called car that has a automatic? A car.
      The transmission on a bike doesn't determine if it's a scooter or not… it's not a step through design .

    4 into 1 is the ticket. The sound is the best. Back in the day I had a VHR 4 into 1 on my 1979 GS1000E Suzuki. One day someone stole my muffler and I had to ride with just open headers for a week or so while the replacement muffler was shipped. It sounded so good I almost didn't want to put the new muffler on. You running your CB750 with the open headers brought back that memory for me.

    • @BrickHouseBuilds

    4:1 all the way! Remember so well when George Kerker made the first 4:1 header back in early 70's for the 750 Honda, they were handmade and had that unique exhaust note so characteristic of his pipes, and they WORKED.

    No comment about the rideability and performance. I have a twin and a 2-1 set up is what I wanted, and I tried and tried and tried to set up the jetting and just couldn't get to ride smooth with soooo many combinations of jets and spacers. Eventually, had to re-install original 2-2 and original air boxes.. Bummer. How come you can get great tuning with BOTH? Not fair!!!

    • @BrickHouseBuilds
      @BrickHouseBuilds  Год назад +1

      I think that comes down to the quality of the air filter, design of the pipes, and being willing to make changes until it runs like it should. It takes a ton of changes usually. Currently been fighting my XS650 and its exhaust which is a poor design for performance. In this case I have to live with 1 spot where the bike has a tiny hiccup. It has taken a ton of combos
