Cummins Idling, 800-1500 RPM's, 800-2000 RPM's, punched the throttle real quick and then turned the engine off.

    The 5" is not as raspy as the 4". It's pretty deep. To get rid of that sound completely you need to go with the 2nd gen exhaust manifold.

  • so the 5" is not raspy like a 4" straight pipe? Mine sounds good but theres too much drone in cab thinking about a muffler now.

    No I still have the stock 3rd gen manifold. I'd like to do the 2nd gen swap.

  • 2 gen manifold?

  • Thank you!

  • nice truck!
