Skip the Gibson headers. They are too short. If you want headers, go with Banks. Otherwise you are better off with just a cat-back system. Gibson headers will reduce low-end torque.

I was looking at the exhaust system. No headers right now. I may go that route since the issue with the studs, but not right now...

Still suggest Banks over Gibson though? Is there a Magnaflow system available?

For Cat-back I don't see any real advantage with Banks. I had a MagnaFlow on my last van (5.8L) and my brother has it on his Expedition. It was a good improvement on both rigs.

I found the part # for the flowmaster muffler 537073 installed at Howards Muffler in Victorville CA Howard does excellent work. the rest of the system is stock.
The K and N filter # 092621 E 0945 at Autozone

Any chance you might have a part number for the system?

On the van, I went the the Motorhome muffler. I'm not sure which version went on the Expy.

On both, it was kinda loud at first, but mellowed out after about 1,000 miles.

I had Ed Hansen Muffer in Casa De Oro install a nice system to get rid of the choke points. I will let the photos speak for themsevles.

Re: 6.8L V10 exhaust and intake...

That is some nice clean work. Is it ceramic coated?

THe Y-pipe is a good upgrade.

I did the Banks setup, but did not remove the cat. It isn't a restriction, and I like being to breath clean air when I'm using the van for stationary power (which is a lot.... it's quieter than the generator), or using it for climate control in the van when parked.

Bill, how much did that run you? Did he install headers as well?

Re: 6.8L V10 exhaust and intake...

WOW! Super clean work and great attention to detail. I've been told a few times that a custom exhaust is better and cheaper than a pre-made one from someone like Magnaflow, etc...

Ed Hansen Muffler in San Diego did a nice job of getting rid of three choke points. See attached photes.
