I used the regular, cheaper pipe not the stainless. I'm in S. Cal and there isn't much of a rust problem here.

The main noise is just more of a throaty sound while operating say from 1800-2800rpm. It's not bad at all but noticable especially at big throttle openings like climbing grades while towing. I also notice it when driving close to a wall or anything that reflects sound but pretty much only with the window down. Even then it's not bad.

also I should mention, I've noticed a mileage benefit. I've towed frequently to the same campground which is about 165 miles roundtrip from my house. Before the pipe, this trip would burn almost exactly one tank of gas, the fuel light would normally come on when I got home or soon after.
After the y-pipe, I've put two trips on to the same campground towing the same trailer with the same load. Both times, I've come back with almost exactly 1/4 tank showing. Now, it's not a scientific test, but if this keeps holding that would be a pretty big change in fuel economy while towing, maybe an extra 2-3 gallons savings per tank? I've not checked the economy while not towing yet.

No headers. I do have a K&N intake but I've had it almost since I bought the truck, so the y-pipe is the only change I've made lately.

I didn't see any Y pipes on SPDs site for the E series trucks, is it not a factor with this truck? I have a 2000 E-450 SD V-10, and know there are a lot of E series V-10s out there, and they can use all the torque they can get.

Stan's Headers, standard and custom high performance header designs for automotive and marine engines.
Stan's Headers makes an quality Y pipe and are great to deal with. There is not a picture on his website, but if you do a search you can find pics on the forum from several years ago. There is one post that compares 3 different makes of the Y pipe.

That is a shame. I bought the Y pipe and a few months later redesigned it for a better fit. They exchanged it for me, no problems at all. You never know, maybe you caught them on a bad day. It happens in all businesses.
The Y pipe they sell is still the best quality I have seen. IMO

Look in my gallery for pictures of 2008 and (presumably) 2009 exhaust. No Y pipe issue there. Totally different setup than the prior years.
