    Default v6 and v8 exhausts same?

    Hey, been a while since i posted, so i hope this is in the right section.

    Got defected on my exhaust being too loud (3" cat-back.. 106dB).

    So i need to quieten it down.

    Does a vn v6 exhaust bolt up and fit properly on the v8? from after the cat of course.

    Cheers!

    Cat back is the same VN-VR V6 and VN-VS V8, providing the axles are the same. EG IRS or live.

    cheers for the replies guys,

    in the end i did the dodgy and cut up some sheet metal with holes drilled in it and put that after the catalytic converter.

    worked a treat on queiting the thing down. really worth a try!

    wow, 106 is loud. that's considerably louder than most motorbikes.
    You're probably wondering where you are. I'll tell you where you might be. You might be in the room that you die in. This is your wake up call.

    haha yeha? Thing was, its a nice note note just stupidly loud.

    Just in case anyone was wondering, the exhaust is as follows:

    From the stock headers it goes into the stock cat, then its 3" pipe all the way to the back then over the diff then there is 1 muffler right near the outlet tips.

    has a bit of bark and a small tough backfire to it. I should put a clip up.
