    ok
    as it stands, glasspacks then side exit pipes behind the tires...

    im wanting to go back to turbo's for noise and performance(they were better at both)

    im thinking of just nixing tail pipes altogether...

    any advantages of having turn downs on the outlets of the mufflers as opposed to tailpipes?

    What about that exhaust when youre parked? Is your rig AIRTIGHT? /forums/images/graemlins/laugh.gif Do you ever wheel through grass? You wouldnt wanna leave it running while parked for any length of time.

    yeah, just aim the turndown basically towards the bottom of your rear tire and you'll be fine. I havent seen it in a wind tunnel, but what I do know is that Im not chokin on exhaust gases in my rig when I drive with the top on or off.

    the theoretical negatives seem pretty irrelevant... i mean, the hottest part of your exhaust is going to be your cat, not whats blowing out past the muffler... if you are parked in tall dry dead grass (and wth are you doing off the trail anyway?!) then your cat will be much more likely to start a fire. parked/running for a really long time? wha? when does that happen? maybe if you're in ur garage and trying to commit suicide or something! /forums/images/graemlins/rotfl.gif

    Mine just end at the muffler (near the rear axle, left side). I planned on running turndowns right on the muffler but haven't got around to it. I only get fumes when the rear window is down, and even then its only a faint (no pun intended) smell.

    mine has turn downs right before the rear end, no negetive effects so far. I don't notice exhaust in the truck when driving, unless the back window is down, but thats a common problem.

    In VA the exhaust must exit out of the passenger compartment. In your case if you lived here, (dont know WV rules) the exhaust would have to exit either out the back, or the sides. To pass inspection you would have to add tailpipes.

    On a pickup its different. You only have to go behind the cab, then you can do turndowns...

    Just my .02..

    be careful if you are stuck in mud with the engine running last weekend we had a guy with this setup almost lose his daughter to carbon monoxide poisening she stopped breathing CPR and gettting her out of the truck saved her so always be aware of the danger.
