Picked up my 2013 crew 4x4 the middle of April and love driving it. Long time GMC guy.

Would like to hear more turbo whistle like a cummins in a Ram. I can hear them a bit with window down.

Don't want to change the whole exhaust. Will a cold air intake give me more?

My AFE stage 2 definitely put more turbo note in my engine sound.

was just going to recommend rolling with a AFE Stage 2 as it doesn't add a whole lot of power (mixed with a tuner does) but really adds some volume to the Turbos.

If your willing to change your y-pipe, our offroad y-pipe will wake the turbos up like you wouldn't believe. And you can keep you stock Catback for some peace and quiet or change to an aftermarket catback in the future.

My AFE stage 2 helped a little as far as noise goes from the turbos, I also added livernois catted downpipes at the same time so I don't know how much of that is from which one. I will say this Catless downpipes will make them scream compared to even a high flow cat.

Dumb question. What are Catless downpipes?

Is cat short for Catalytic converter?

Just clarify what we are talking about.

You are correct. Catless downpipes are offorad downpipes. Meaning they have no catalytic converters.

And usually catted aftermarket downpipes utilize a small more high flow cat.

Intake will add more noise... A tune will add more noise... Mak y pipe will add more.. BUT remember these turbos are smaller than your typical diesel turbo. I don't see these turbos being at the noise level of a cummins / modified super duty.

I agree, I just have the AFE Stage II and love the volume increase. When I tap the throttle at 1500, it sounds an aggressive whoosh of air.
