Did the SPD Y-pipe upgrade.

Did the SPD Y-pipe upgrade.
I couldn't find the old thread we all talked about this, so created this new one.
I put on the SPD Y pipe yesterday. Only took a couple of hours, the vast majority of which is cutting, fitting, cut a little more, fit some more.
Anyhow, that is all I changed was the Y-pipe. In the previous thread I had mentioned that 2 years ago I had replaced the P/S manifold studs with the improved Ford pieces, due to the originals breaking. About a year after that I developed another leak and figured the bolts had snapped yet again. I was wrong! The manifold had a small rust hole / crack in the bottom near the block, but I was able to weld that up.
Eventually I will be adding a new muffler, the stock one is leaking where the straps hold the heat shield.
But I did nothing but the Y-pipe so I could verify its benefits.
Sound: I think the truck has a little deeper tone at idle. While driving, you can hear the exhaust a little in the Y-pipe area under the floor. Its not a leak, you can just hear the hollow sound of exhaust flowing through the pipe.
Performance: Off-idle throttle response is much more instantaneous. At low RPM I can feel a big difference. I mashed it a few times up to about 60mph, feels like the motor revs a little quicker. I have not towed anything yet, and I think that is where I will see a big improvement.
Does it add the claimed 33 hp? I don't know, thats a lot for just a Y-pipe upgrade but the stock piece HAS to kill at least 15hp.
I am very happy with the change, recommend it to anyone's truck with that piece of poo stock pipe.

SPD Performance I bought the stainless version, because of the salt during the winter in Ohio. Mine was $129.00.

Careful when cutting out the original Y-pipe. The factory steel is double walled and tuff! Get many sawzall blades. You will see that after the Y, the exhaust heads towards the Cat. There is a bolt together union just before the cat, just ahead of a cross member. All the vibration from the saw broke the pipe off at that union. I had to re-weld that as well. Wasn't too big of a deal, bud it did add to the work.

Im in the same boat. I bought the SPD Y about 2 months ago, but haven't had the time to get it into the shop. I don't own a welder, so i called the local exhaust shop. They quoted me only $80 to do it... I just hope all that vibration doesn't pop off all my exhaust manifold studs...
Maybe i will request that they use a plasma cutter to get the old pipe out.

Here are a few articles about the Y-pipe.

To me, with my '01, which already had ebay headers and a VOlant intake, the y-pipe did NOT increase the max HP.
If DID however greatly increase the throttle response at low RPMs. Much nicer to drive in stop-and-go traffic, but overall I don't think it really added anything to the max HP.
On top of those mods, I added the 5-star 87 octane performance tune, and went from a 10 second 0-60, down to a 9.02-9.04 second 0-60, confirmed with datalogging. Amazing
