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.

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.
