    Hello everyone

    I just put on dynatech headers with high flow cats and 4" round magnaflow mufflers(14" length). Got custom true dual that exit on an angle right before the tire.

    It sounds amazing at idle and up to 2000 rpm. When I get on it past that, it is way to loud. There is huge roar and a tremendous amount of popping. I like the roar, but don't want that popping at all.

    I've heard the 6.0 L76 opens up when you put on performance parts. I didn't expect this tho. It sounds like there is only headers on the truck. Lol

    I've read that a bigger oval muffler will help

    Looking for advice on what to do. Thank you

    Popping when you let off? lack of back pressure will do that

    Muffler and X-pipe will help smooth it out.

    Your outlet be to open, so the gases come out with the poop. Need to reduce flow.
