    The inlet size wil have no effect on the hp, or noise unlesss you increase the tubing in frnt of the muffler. The outlet is a different story. That will effect the sound level, hp, and tq. You can go to big and you will lose low end tq. But you an not really hurt the engine. You need an offset inlet to line up with the stock pipe. If you use a centered it will hit the frame and or the drive shaft.

    I've been using a Borla Turbo #40658 with a 3" Dynatech Vortex insert cone in the exhaust tip & like that combination.
    It's fairly quiet at idle & not raspy/ ricey sounding under hard acceleration, but still fairly loud.(I was able to pass the MN state db test last fall while wheeling @ Gilbert, MN OHV park.)
    I found the Borla muffler alone to be too loud for me, so I experimented with a Supertrapp tip for a while, but found that to be too quiet/restrictive & just plain didn't like the way it looked.
    The insert cone is perforated & took a bit of hammer work & more than a bit of foul language, to persuade it to take up residence in the tip...hope I never have to remove it.

    In order to use the stock pipes you must get a in / out on the same side. I used a flowmaster 40 series it was the only one I could find the right combination in. shawn

    Hey, I didn't know that. Thanks, Shawn!

    Is it really vital to use the stock pipes? I don't know how much it would cost to have a muffler shop bang around and fit some new pipes to make another muffler work. I've seen some VXs with dual-exhaust set-ups, and I KNOW they had to have some custom piping done.

    I'll have to respectfully disagree with you on that psychos2...mine lines up just right with the front centered & the rear offset.
    As they say...there's more-n-one way to skin a cat.
    Also, sorry for the insane corrodicity under there...it's been a sloppy cold rotten winter.

    Cool! More options!

    Again, though, has anyone ever heard of blacked-out exhaust pipes or exhaust tips that might match those diamond-black Flowmaster mufflers? I haven't seen anything like that online...but it sure would look cool on an Ebony VX!
