Weed Burner Exhaust Question

[marek4792]

I'm also looking into running a grassburner setup on my cm870 truck is a volvo vnl model my question tho my exhaust pipe runs along the top of the frame rail to the stack. If I make my grass burner setup run from the dump pipe outside the frame (behind the passenger step) and back under the frame like the Mack in the video above, would the extra bends add enough back pressure to not overboost/speed the turbo without a muffler?
