Ok, so today my dad and I went to Lowe's after he had went to Home Depot to get the stuff for the intake. His search apparently turned up little at Home Depot and at Lowe's we were only able to find a few things. We just bought the 4x3 connector piece. The employee there said he didn't have the black DWV ABS pipe!?! I know this is a pain to ask, but those of you that went to Lowes or Home Depot, what were the part numbers if you have those handy?

 

I had to buy 3" white schedule 40 and paint it black.

I bought these parts also, at Lowes:

Pipe Hub Donut 3"x3" RPHD75 70389
Downspout Connector 4"x3" RDSC 23455
One 4" clamp

 

Thank you for the help
