OK, so I'd like to delete the DPF on my 2010 Ram but keep the CAT. I don't want loud and some have said deleting the DPF increases exhaust noise.
Does anyone make a delete pipe that's a muffler? If not has anyone had a custom delete built with a muffler?
Also, I assume EFI Live is the way to go? Does it control the trans as well?

 

Another question.
Is the DPF delete a straight pipe or are there any bends in it?
Does anyone know the exact length?

 

I did the turbo-back delete but kept stock muffler. It's not that much louder, but you can hear the exhaust brake when it engages. Also, on a cold morning, it can be pretty loud when the EB engages to help with warm-up.

I didn't to the work - paid a shop to do it. But it's my understanding that if the only thing you're going to delete is the DPF you just buy a straight pipe. Don't think there are any bends in it.

Tuners would be a personal choice. Just get one from a reputable company. I went with the RaceMe Ultra. Comes with trans tuning out of the box.

 

Anyone experience transmission issues after their delete and tune? What kind of HP increases are you guys, running?
