    Has anyone ever ran full 3" exhaust. Cats, resonator, and third muffler deleted. Only keeping back mufflers but replacing with aftermarket. Will there still be enough back pressure or would you lose power?

    You dont need too. Just downpipes and the rest of the stock exhaust will flow anything you throw at it.

    If you wanted to do a single out with 3" it would make more sense, powerwise. Or even 3" downpipes (tight, but doable).

    Yes, I managed to put a full 3 in exhaust from the turbo’s back. It was not easy to say the least to fit in high flo cats and have 3in bends around the subframes and keep it close to the unibody and then around the rear diff.

    But it is doable if you are dedicated to do it. If you are in a state that doesn’t require passing emissions then I would recommend not having cats, it would make the job much easier with more room to work with.

    I used two vibrant resonators and high flow vibrant mufflers.
