    I am looking into purchasing a dual exhaust kit for my truck. I had a Flowmaster Delta for my 2001 which sounded great, but now own a 2007 Doublecab. I am very interested in the Flowmaster American Thunder Series exhaust kit for my truck. It is bolt on. Is that ok or does it have its cons as well. If anyone has a video of what it sounds like please post. I am curious to hear what it sounds like. By the downloadable instructions, it seems pretty simple to install as well. Big savings.:confused:

    I always think fake duals look silly in the winter with all the exhaust coming out one side...

    Doesn't a pseudo-dual also dick up backpressure and cost some torque on the 4.0?

    It's a nice mild tone and sounds good from the outside.

    I've never heard a sound clip of the american thunder, heard someone on another thread say his friend had it and it sounded good. But of what ive heard i like the super44

    EDIT: didn't realize this thread is so old.

    It's got a mild tone to it, not too loud at all. It got quiet for me after a couple thousand miles, replaced it with a Flowmaster 10.
