    Hi. I need your advise to choose one of these exhausts.

    Because of cost I'm rather thinking about 4-1 exhaust with universal free flow muffler. What do you think about it? Maybe 4-2 exhaust is better?
    Maybe it's better to leave OEM exhaust? I rather wouldn like to loose any of my HP.
    Generally I would like to change my exhaust because louder is safer option in the city.
    I know that I need to re-tune my carbs. Thank you very much

    Get your carbs cleaned and tuned, your valves in spec to before you buy a new pipe.
    That way if the bike starts running bad when you fit the new pipe you know its just most likely going to be a rejet.

    Don't remember (getting older though) reading comparison of 4 into 1 versus 4 into 2 as far as performance is concerned. I think it comes down to which set you think looks better....

    btw my vote goes for 4 into 2 (JMO)

    My idea was to fit 2 or 1 free flow exhausts. But only free flow ones.
    Any more voices?

    Then leave it stock and get it running 100%; and buy a louder horn if you want more warning capability.

    Start messing with the stock exhaust and you WILL change the power delivery characteristics. Generally you will narrow the usable rev range, and give something up for any gain elsewhere in the power band.
