Question

Help answer this question below.

If you cut out the catalytic converter and muffler and put in a 3 inch straight pipe all the way back, will it improve hp, torque and fuel consumption? And will it be better for the truck itself or is it not a wise thing to do?

    Being a certified mechanic, it is of course illegal to cut out your cats. However, it does improve horsepower, low end torque, and gives your exhaust just the sound your looking for. It completely gives your exhaust a large opening, being that the the faster the exhaust is expelled from the motor, the better it will be. From my experience, I would do it.

    Well I'm not a Certified Mechanic but a retired telecommunications tech
    but I have spent 50 odd years under a shadetree. Are you wanting to replace your Cat Converter and muffler with a straight pipe from exhaust manifold to rear bumper?Improve ..I think so but not wise.I once had a motorcycle that sometimes the muffler would fall off and it would almost jump out from under me. But, it Wont pass inspection and excessive noise tickets for sure...

    Today's engine are designed to run best with a given range of back pressure in the exhaust system; disrupt that and there could be a variety of changes in behavior, not all of them good.

    it will help for a short time because the catalytic converter is making back pressure when it isnt running correctly but it will be very loud and as long as u dont live in california or go there alllot you wil be fine but u eventually need to get a new catalyic converter because it will be hard on the engine
