Powermax...... No more Howling!!
Powermax in.
All back together. Took it for a little drive.
First, smoking some. I'm thinking it is burning off new oils and stuff from manufacturing . I see zero oil coming from either place, feed line or the drain tube.
Now, when I had it out on the street, I laid into a little bit. Like 5.5 lbs. of boost.
It howls like a train horn, I let off and it stops. Lite throttle and it doesn't do it.
Could I have not gotten the up pipe totally connected right? It sure looked good from my angle.
Any thoughts folks?

Yeah, I am going to stop by Harbor Freight in the morning and grab a ratchet strap, and see if I can't get it any closer. Man, I sure thought it was right where I needed it. But, I'll see if I can do a better job.
Thanks for your input.

I was fortunate enough to seat my 03 turbo first time when installing and didn't have any leaks etc. I also put on a new exhaust at the same time so the downpipe was more flexible cause it would pivot and stuff easier. Lol

Driven they can look real close but if its not perfect it will leak. I wouldn't use a ratchet strap just lousen the up pipe bolts and it will pop right in most the time. Hell i wish that was my only problem.

When you said Howel I thought you ment at rear exhaust pipe
so the howel is coming from the engine Bay???
If so then probably Ypipe to turbo connection
That turbo can be a PIA
I set turbo in the Pedistall and the Ypipe is the very first thing I hook up
I set it in pedistall then Eyeball the Joint and found to make a perfict reveal around the joint I had to push the Ypipe towards the firewall. So then I smeared antiseize on the Marmon clamp flanges and Installed the Marmon clamp Loosely on the Joint. I then setup my air ratchet on the clamp bolt and Gave it the same push (what it took to make the reveal even when I had the clamp off) toward the Firewall as I Sucked clamp tight with air ratchet and worked like a Dream. once you get that your Golden

Sorry to hear it is not meant to be yet. Best of luck getting it seated properly. -Mark

Well, here I was so concerned about the up pipe getting on right, that I didn't pay enough attention to the down pipe connection!
The down pipe was the culprit. No more howling.
But, she does whistle more. Nice having Her back on Her feet!
Thanks you guys!
Oh, I had purchased some smoke bombs on sale a few years ago (after the 4th of July) just for this very thing. Dropped one in my shop vac. Worked well until the dang wind shifted and filled the front of the truck with smoke!!!! Well, it was a good idea any way!
