    Muffler Disconnects - Harmful?

    I've done a bit of a cheeky today and gone and disconnected the pipe from the cat just under the passenger seat on my TB42e.
    I like the sound, and that's all I've done it for, but I'm wondering if I leave it like that will I regret it.

    Am I harming my power or fuel efficiency?
    Will it suck up water?
    Are the fumes gonna do any damage?

    Will it suck up water? highly possible if you are submerged and you stall the motor
    Are the fumes gonna do any damage?Only to your lungs.
    Its also illegal, AFAIK, all exhaust exit points must be behind the rear wheels. Or something like that.

    Won't damage the Car, won't help the Planet, will damage your brain which is why lots of people choose to kill themselves that way as Carbon Monoxide is a) odourless and b) painless
    Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.

    Yeah the sounds nice but in the interest of not smoking myself out I reckon I'll screw it back in.

    Who else on the planet likes the sound. if its a TD just go straight to the back
    no muffler. Personally I dont like the sound eh but each to their own.
    @mudski its must exit behind any opening window so a Patrol wagon must
    out the back, keeps fume there as well
    Do a given drive to check your fuel figures
    then repeat with the system mods.
    Going to a 3" system with a racing cat should see a power gain

    EDIT,,,,Besides being illegal so much noise will attract any

    Yeah I love the sound wheel of my Garret spooling up. When I do drive my Patrol, it’s usually with the radio off and the lhr pax window open. Those sweet sounds of the Garret whistling away is better than any music.
