i am looking for 4.5 and 4 in stainless pipe.....The same stuff they use to make exhaust.......I want to make up a sepereate set of totally dery pipes that exit above my rubrail.......I dont car if it is dull plain pipe...................

McMaster-Carr has stainless in all sizes and any grade you need.

I used to go to the local steel supply house. They can get it, but not the best price. You may try some of the exhaust places, or scrap places.. See if anyone has it and is willing to sell a a decent price.

Let us know what u find..

D*ck

eddie marine, sold by the foot polished or raw. They will also cut the length you want.

I have 4.5 tails from a staggerd scarab. They are 4" inner and 4.5 outer tails. You could possibly cut/weld them to make them fit. They are stainless.

I currently have some excess 304L x 4.5" , .065 wall and some 316L x 4.0" x .083 wall. Just PM me if interested. Thanx
