Exhausts

    Exhausts and all that jazz. Not that I have the time or funds to change my stock exhaust on my cb400 1994 I was just wondering what my options would be. It would just be a stuby/muffeler slip on type and not a full change, if that makes sense. For example would a cbr400 of vfr400 exhaust do the job? What are the important things to consider if changing an exhaust. Not having to adjust carbs is a bonus. It would not be for HP gains maybe just something that sounds a bit better ( although the stock one aint that bad )

    CBR400 should be very similar, although any time you change exhausts your jetting will change.
    Intake mods affect it more than exhaust but any change will make a difference.

    Does cutting the exhaust always mean having to weld the new one on or can it be just clamped on?

    My brother had one - cracking bike. If you can get an end can thats the same diameter as yours then a slip-on can can be clamped. He ended up getting a link pipe made up and had a Micron end can off a bandit fitted. It caused a big flat spot in the mid range but a bit of messing with the jetting sort it out.

    The thing with bike exhausts is that its easy to make more noise but genuine power increases usually happen high up in the rev range and bottom end may suffer.
    Exhausts need a certain amount of back pressure to make good torque at lower revs and free flowing ones mostly don't provide enough.
    They sound good though.
