There is "straight" sewer pipe that is schedule 20 PVC, usually used for septic systems. It's gonna half to 2/3s thinner than schedule 40 and much more flexible. It may be flexible enough to squeeze into the oblong shape in the inner fenders. If it couldn't be squeezed into fitting in the hole you wouldn't have enough material to shape it into fitting though.

Ya'll gotta keep in mind that these Lowes, Home Depot folks generally aren't "from the trade" so they might not be familiar with the products and/or what their intended purposes are.

FWIW, my local Lowes had the PVC test caps that AgentOrange used in his build. I used a 2" and a 1.5" test cap. Need to go back and get a 1" plug for the other hole.

I'll post a couple of pix when i get the plug but I've trimmed the rims off the caps & I'll do the same to the plug along with cutting it short so it doesn't project so far into the intake's air stream. Gives it a pretty clean look.

The guy at Lowe's told me to not screw with the intake on any vehicle "the manufacturer builds them like that for a specific reason"...after I told him what I was doing with it. I said, "Well, my reasons are different than Fords". He didn't offer much help.

Oh yeah, I wouldn't tell them anything like that because you might end up with some hard core enviromentalist or something. I always leave it vague and tell them it's for a "project i'm doing..."

I can only imagine the look on the dude's face!! :disbelief::notallthere:

The main difference is what it is made out of. The black pipe I used is ABS and is labeled DWV on the roll stamping. PVC should work as long as the outside diameter is the same. I have not tried PVC myself, though.

DWV vs. sch. 40
 

Since I've been following this mod here and at F150online I can't remember which thread it was mentioned in...

DWV in ABS should be dimensionally identical to schedule 40 PVC.

DWV fittings in PVC will fit sch. 40 pipe & fittings, they're just not rated for pressure; hence their classification as Drain/Waste/Vent.

The reason some of you can't find black ABS piping is because either state, county or city codes don't allow for it. The only advantage to ABS pipe (other than being black already) is that it is cheaper than PVC. But similar to schedule 20 PVC it is not as durable as sch. 40 so many codes do not allow for it.

For the small amount of pipe/fittings being used you might as well use PVC if you can't readily find ABS and not sweat it. A little flat black paint and it'll look like ABS...

I got all of the parts today. SCH 40 PVC works with the downspout connector perfectly. If March Madness would go away, I'd have this done tonight, but it's looking more towards a tomorrow morning project.

Got it all installed...It's probably in my head, but the intake "noise" sounded louder.

I'm thinking a PHP sticker on there is in order!!! Hopefully it would mesh nicely with my Gryphon and new catback.

That's the only thing I miss... I got a bit of intake noise but nothing like what you get with an aftermarket CAI.

I grew up on carbureted engines, I WANT to hear that intake roar when I go WOT!!! The Volant I had on my '99 F150 w/5.4 was delicious! Sounded almost like the '76 'Burban 4X4 400 w/Holley 4 bbl I drove in high school... and $.68/gallon gas to boot! :2thumbs:

Be prepared! When that sticker goes on it instantly adds 35 ponies!

Just kidding!
