A stainless Magnaflow Y-pipe is under $30 shipped on ebay...and roughly the same price to have it welded in at an exhaust shop. It make a huge difference in flow, even from the early 99-00 "ramhead" stock y-pipe.
I suggest having an o2 bung installed at the same time (in the 3in pipe post y-pipe), a wideband afr gauge is good.

That Magnaflow Y-pipe may sound great in principle. I thought that it was great too so I bought one and installed it on my 04'. The flutter was horrible, 10 times worse than an SPD. I guess it all worked out because I had Thorleys on my truck in less than two weeks after installing that mistake.

I don't think I have "flutter" with the Magnaflow Y-pipe, but there could be some impact with the different length tubes before the Y-pipe. The SPD setup does the exact same thing, their actual Y-pipe is no better or worse (and I believe they charge more for stainless steel). Did you try a SDP Y-pipe before you changed out to the Thorley's DKF?
The Thorley setup incoorperating the Y-pipe is nice, but it creates un-equal length header pipes also...the passenger side exhaust lenght is shorter that the other side.
Maybe it was 5star that had a pic of a v10 w/ Magnaflow y-pipe (with equal length header pipes), this is may be the best approach overall, but it's hard to keep it tight under there...and would likely require moving the cat also .

My mechanic friend made the same suggestion. At the time I planned to keep the engine\exhaust stock and didn't give it much thought but now that I installing headers and a Y pipe I may as well add the O2 sensor and gauge. I have been wanting to add a rear differential temp gauge and trans temp gauge anyway.
Do you have any pictures of your install? Where did you buy the bung? Thanks!

I hate being so ignorant but what is flutter and I going to have it with Gibson headers and the 5Star Y pipe?

Engine failure.
I was towing my 10,000lb toyhauler out to the Superstition Moutain OHV area from El Cajon, CA on new year's eve with my 2002 Excursion with 61,000 miles on it. The temperature was in the 30's on the mountain pass and I was running 4000-4500 RPM quite a bit.
I have read on the Excursion forum that it is no problem for the V10 and I have done it a lot on 90-110 degree days with no problem over the last 7 years. But I guess the much cooler temperatures caused a lean condition that melted the #4 spark plug. It dropped debris into they cylinder. Below is the dealers estimate for the repair.
The sad thing is I had a 5Star tuner on my todo list for the holidays but didn't get around to it. Now I need the tuner and the repairs!

I saw this thread awhile ago and never looked at it until today. Glad I did. I have a set of Bosch plugs that I was gonna put in this spring. Not happening now....gonna get a set of motorcraft ones then.
As for the gas with ethanol, I used to have a station that sold straight gas, but now they switched as well. One solution is there are products out there that "neutralize" the ethanol. Like mentioned before, the ethanol loves water. I'm wondering if dumping dry gas in once in a while would help with moisture problems. I work on small engines on the side and have seen adverse problems. The major one is ethanol hates rubber. So all gaskets, hoses and such disintegrate more rapidly.
I hope you have good luck with your repair.

Flutter is a sound produced in the 2k rpm range and is somewhat hard to described. It is sort of a pulsating hissing type sound that some may think is an exhaust leak. I'm somewhat convinced the poor design of stock exhaust manifolds has a lot to do with creating the flutter sound. Your Gibson headers should be ok and not produce flutter. Several here have reported no flutter with their shorty headers.

It's isopropyl alcohol, I bet. The marine industry is full of that stuff in the past few years. Almost all of it smells just like isopropyl alcohol.
The only way to get rid of the alcohol is to distill the gasoline.
