    Default twin exhast for v6 help

    hi im gona be doin a nu exhaust for my v6 and i need opinions.
    i want twin pipes cause i want it to sound as beasty as pos. heres wot iv been dreamin up.
    extractors into twin 2 inch, no cats as its nz spec, two long coby resonaters (one each side) merging into 1 single 2 and half inch pipe just before the diff,out the back im not sure wat type of rear muffler to have fitted? defnaty strat through tho.
    i was thinkin it would be cool to have some type of dump pipe straight after the diff exiting to the side a bit with a removable cap (old hotrod style) 4 the drags.
    wat i need to no is is, is 2 inch the best size for the first section? and 2 and half best for the rear part? i would like it to flo the best it can.
    wher should balance pipes(1 or 2) be fitted? or should i go with a x pipe?
    all opinions would b great as if been searching the net for agis and i dont no if this has been done before on a na v6

    from the extractors... 2 1/4" then from the resonators 2 1/2"


    This will not only sound good but would be optimal for performance

    if you want twin exhaust, whya re you merging it, why not just keep it twin 2" all the way through, have a decent straight through muffler in each pipe and a cat. and youll have a decent note.

    Won't go on a VN though, it's a live axle. It will be difficult to put a twin system all the way through on a live axle car. It can be done but it's not straight forward.

    What you originally wanted is fine, twin 2" off extractors, but I would run them side by side down the same side and into a twin in single out straight through muffler, then 2 1/2" out the back.

    cheers for evyones input, yea the reason i was planin for single out the rear was cause there ant much room between diff an body on the solid axle vns.
    il b lookin into these v8 of the shelf sistems i think an way up the cost o gettin one made up (my dads a mean welder so il just have to buy pipes an mufflers)
    will post pix wen its all done
