Cummins revving the engine with 5" straight pipe

[turnerdhr]

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.

@turnerdhr

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.

2 gen manifold?

@RM250D8rzr

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