    hypothetically ...
    \ /
    if someone where to cut off and steal my CAT, and then for some odd reason my muffler fell off (rust and such, you know these well taken care of yotas).... and I found some piping I could clamp on to get the exhaust piping from underneath the van, no carbonmanoxcide poisoning please ( https://www.oreillyauto.com/detail/c...t+pipe&pos=461), what would be the mechanical problems that would develop over an extended period of time?

    location I am at, Sucklahoma, has no yearly inspections.

    About a month ago I noticed my exhaust was pretty rusted and had a leak around the middle the way down the length of the van. There's a point at which you can just unbolt most of the exhaust after the little flexible joint. Pretty much right where my leak was. I thought that flexible joint thing was a cat at first, but its not.

    Long story short, I just unbolted it there and removed the whole thing. It feels like it has a little more power, can't say its a ton but its something. Its actually not that loud because of the turbo and I've been driving around with no exhaust for the last month. Just idling and driving around real easy, its not that loud at all, but you can definitely hear it when I step on the pedal hard. I plan on leaving it this way unless I start noticing fumes. Probably just put a straight pipe on there to move the fumes away farther. Added bonus: you can't hear the kids complaining in the back cause it drowns them right out! Probably works for parents, in-laws, spouses, and significant others too!

    In case you're curious, I live in California but the van is smog exempt so no worries there.

    Glad I did it, the muffler was bad and I didn't even know.

    not really any louder, I can clearly hear the turbo whistle, which is what I wanted
    Also, weight reduction bro.

    I'll be watching the MPG and see if any help there.

    One issue I have noticed is, when in gear, with no throttle, just let off the brake peddle and let it creep, like backing out of the garage, the van shakes. If I give it throttle or put in natural or park the shake disappears. I wonder if the air / fuel mix needs adjusted now that there is less resistance, back pressure from the cat/muffler, I guess?
