    Do you have pics of how you routed your exhaust from the turbo back. I like the packaging but can't for the life of me figure out how to route the downpipe to the mufflers at the back of the truck, seems like just no space.

    There's room for a 3" or 4" downpipe on both sides if you wanna make it fit.
    Turbomic has twins and both his fit; it's a tight fit but you can do it.
    And the ccab sleeper has them:
