:confused: So I cant' decide on which to go with both will be downpipe back. I like the dual look but it's cheaper to go with the 5". What's the majority opinion?

5 inch is overkill and not needed on a stock turbo in my opinion. Not to mention the droan is too much for a daily driver

Running 4" duals with a mbrp downpipe and I like the setup because when I'm driving its very quiet in cab. 5" single sounds way better IMO though. Drone isn't horrible with a 5 atleast not in my old 06lly.

I run a 5 inch with muffler and theres no drone?

I know its a truck, but from the car world, duals just add un-needed weight.

A variable vane turbo won't have drone like the lb7 would. I Flopro 5" will work great. I have one on a LLY and lb7. LLY is pretty quiet inside the cab.

I have MBRP 4" cool duals. I love the way it looks, I run the MBRP muffler also. Not too loud while cruising around, but growls when I get on it and sounds good to me.

Duals are pointless. A single 4" dumped sounds best IMO.

I used to think they looked cool, but now, I love my 4" magnaflow. And after looking at duals, I dont really like them much anymore, they are more expensive, and you dont need them even pushing high power...so in long response, I agree with skank. :hug:
