    hey flash, i am currently running the mac 4into 2 megaphone system and i love it. my ride is an '83 xj750r seca and the mac system gives you plenty of clearance and great access to your service points and the sound is not overly loud but a nice little rumble as long as you leave the baffles in.
    if you do a search (look for changed exhaust system) there is a photo of my bke with the system installed. might just give you an idea of what you may want. cheers mate

    I'm running them on my Maxim-X chopper and have no problems at all. They are the slash cut, not megaphones and sound awesome. Lots of clearance, easy to install and no collector to worry about. No rejetting was necessary as I kept the original airbox setup. Just need to finetune the mixture.
