6.0 exhaust system.

Nickxxxr · Apr 26, 2015

Looking at buying a turbo back system as my next purchase. Problem is, I'm not finding some of the info I'm looking for. For one I want to do dual stacks. So I'm looking for a kit that is 4" dp to 5" straight pipes all the way to the bed into 6" stacks. This trucks my play toy so I do want the sound. All the kits I find that say 5", don't tell me if it's a 3.5 or 4 dp, or say if it's 5 inch all the way back, or 4 inch to the bed than 5". Am I not looking in the right place for info? I'm so confused after looking at so many different kits.

Most all kits will be 3.5" down pipe to 4" piping. Then you choose what size stacks

I'm pretty sure the MBRP 5" kit is a 4"dp to 5". Thats what mine is anyway. And I'm pretty sure you can buy a stack kit that includes a dp and flex pipe and the clamps and all you have to get is the stack/stacks.

You have to specify that you want a 4" DP. If you don't, they're all 3.5" - unless stated otherwise. I've had three 5" MBRP kits, they've all come with a 3.5" DP.

Ahh, I understand. My kit I ordered came with a 4".

But, I'd go with a 4" dp to a 5". I really like my MBRP system. Worth the money. Definitely get the stainless.

Aluminized is a waste of cash?
And so I'll get a 4 dp if I specify on my order, OK that helps. I couldn't find sizes in any of the specs anywhere.

So this should be a system that is 5" from dp to stacks correct? And all I have to do is specify a 4" downpipe
I contacted mbrp about this already and never heard back from them.

Another vote for stainless as well. PM me if you want a great price on an exhaust for your truck.

Yes, aluminized is a waste of money. Get the stainless. But, specify with whoever you order through that you want a 4" dp

I ran a 3.5" downpipe on my old '04 with no issues. Back in the day, they opted to go with the smaller downpipe to avoid fitment issues. Maybe things have changed since then; it was like '06 lol.
