Weed Burner Exhaust Question

[Grizzly]

I have a 2009 ISX 871 that I'm wanting to put a generator (redneck apu) on. Its fits one way on one side and another way on the other. I'd much rather have it on the passenger side however my exhaust stack is in the way. Ive thought about removing it in favor of the weed burner style exhaust.
The question:
Will switching to a weed burner style affect the motor in a negative way or positive way or neutrally. And how?
Not looking for the "you're gonna piss people off" "i hate weed burners next to me" "they suck" answers, I've already seen those.
Closest answer Neutrally I've gotten from a tech is he didn't think it would much matter after the DPF.
I'm thinking back pressure, turbo spooling items like that which might be impacted.[/size]
Thanks
