    You removed the muffle as you stated in the title, meaning you are breaking the exhaust noise level limit law.

    Needs a full "coffee can" (aka "fart can") outlet treatment...

    Oh, and add a turbo bypass (aka "pop-off") valve. What? No turbo, you say?

    lol your the 2nd person to mention turbo. That's only in my name. Anyways i'm pretty sure a turbo couldn't be installed unless some serious mods are done. What's the Fart Can Treatment?

    I'd love to do it to mine if I have the chance! Just curious, what kind of mileage increase/decrease did you get from this?

    He has several videos posted on YouTube: Steve Saephanh - YouTube

    With my DC header, 1 OEM cat and no resonator with (2) 6" round magnaflow mufflers - My Prius was waaaay too loud. I ended up with (4) 4" round Magnaflows in all. 2 where the 2nd cat and resonator used to be and the other two custom welded up like so:

    It would be cheaper to make your own out of (2) 4" round magnaflows and some mandrel bends. That setup from Japan retailed for over $1200

    fartcans are much cheaper.

    ...probably drives like a Prius.

    I can't imagine an exhaust tone I'd less like to broadcast than that of a Prius.

    Suddenly I feel very old...
