    So my first thought was to get rid of the rear cat when I weld in the new muffler. But... I can't find any 2.75'' pipe.

    So now I'm thinking about keeping the cat and splicing in the muffler

    Or ditching the cat and just putting a turn down right after the muffler

    Have you went to an exhaust shop? Summit, flowmaster, dyno Max all sell 2-4' exhaust tubing ranging from 25-50.00.

    I do believe you will have to buy the rear O2 sensor delete kit.

    The rear set of cats are passive, so you won't need a sim for them, but there isn't any reason to delete a set of cats if you aren't installing headers. What's likely to happen, taking a set out without doing headers, is the truck may lose some low end torque.

    Also, doing a turn down after the muffler will most likely lead to a loss in low end tq. The tail pipe is needed to keep your low end.

    Not very fun news, but better you know now.

    I'll send you the perfect muffler for free, in trade for the rear cats.

    The muffler that I send you will be legit, check out my site dirtydeedsindustries.com
