FZR400 exhaust question

    Just curious....can an inline 4 run an exhaust that looks like a 2 stroke? You know, the big expansion chamber below with the small mufflers as an outlet. I honestly don't know and I'm just curious. Does it mess up exhaust flow which can cause performance to be bad? 2 stroke exhausts just look so badass.

    Legit question. Just wanting to learn something.

    Can you? Sure. Will your bike be a dog after, highly likely. :D

    Seems like it would choke it out and stall. Get a tzr250 for that fizzer look with beautiful chambers. Speedwerks.Done.

    If it has to be and you want to look like a total idjit, leave the original headers in place and fab a 2-stroke chamber over them. Other than that, header diameter and length has direct effect on torque and powah .

    That's kind of what the EXUP valve does.
