http://www.mcmaster.com/ has the 6" pipe. Pretty expensive though

 

wow.... didn't read the original post at all...

He is asking for 6" pipe, refering him to a place that sells 2" just isn't going to cut it.

He already has flares for 6" piping, just needs extra tubing for the middle.

 

Seemed like a logical question to me.

He wants 6" PVC/ABS... 2" ain't gonna do jack for him.....

Unless you know a way of stretching it!

 

Righto - commercial plumbing distributors. Some names to start with: EMCO, Bartles & Gibson

 

If u don't mind HD carboard tubes....... the Brown Bread 1/2 shop rolls comes in a 6" carboard tube. which are excellent for porting large subboxs.

 

Look for a supplier called Noble Trade... they carry everything for plumbing.

 

Local plumbing store here in saskatoon has 6". Just try any plumbing store. They should have some in the back, or know where you can get some.
