Exhaust

psd1011 · May 8, 2013

Need to know best way to remove muffler and stock tip.
I have done the DPF delete but the muffler and stock tip is still on it,

Is there a exhaust pkg that I can adapt to the straight pipe just behind muffler?

Thanks

should be able to buy a filter back exhaust kit and bolt em right up. not sure on how it reduces. but it'll be the right length.

you need a dpf back kit.

stock down pipe size is 4 inch, but is double walled, so its biger than is appears.

Sell what you got and buy a 4" or 5" turbo back kit from somebody. What you are trying to do will bottle neck. Been there done that.

Had not planned on buying from them, just finding a kit part number that I needed. I think my dpf delete pipe is 4in so a 4in filter back kit should work perfect.

yes your DPF delete should be 4" so either get a 4" dpf back exhaust or even a 5" and youll be happy

It bottle necks down to 3.5 to incorporate the stock tail pipe. so he will have 4" to 3.5" to 5". Seems legit.

i have a 4" dpf delete that goes to a 4" dpf back kit, and its all the same size, it doesnt go to 3.5" where the dpf delete and dpf back exhaust connect.
