Dump Pipe bends

[benl1981]

Does anyone know where to get 3" mild steel bends to make a dump/front pipe out of. The local exhaust shop wants $30 or more each. This makes it costly if you f..k up...

Sydney, if possible around nthn beaches.

Also, How about steam pipe/schedule 40, you can get this from the hardware about $8 a bend. People use this to build manifolds. Bit thicker than required. Wall thickness is around 4-5mm. Might be a bit harder to work with and heavier but probably last forever. Any thoughts on this?

Thanks

PS I am going to MIG it togather, I know someone that might be able to plasma cut the flanges for me. I have a spare dump pipe to trace the flange required.

Goal - to build 3" combined Dump/front pipe for under $120

You gotta use mandrel bends if your going to do if properly, unfortunately they do cost a bit you can save money by buying a 180degree and cutting in half if you need 2x 90degree bends

steam pipe is in short supply at the moment so get in now if you can ive been told 2 months before new stock arrives

Don't know if this helps, but you can get 3" stainless mandrel bends for $20-30 from just about any stainless distributor.

If you are careful enough you wont make any major mistakes. Just start from the front and work back. Tack each section in place progressively and perform lots of trial fits before the final welding.

Thats pretty cheap. I think I will stick to mild as I have mild steel wire in the MIG at the moment. Mild steel should be cheaper..

What you might find is that mild steel is approx the same price because it not very high demand.

Although not ideal, i'm pretty sure you can weld stainless and mild together.

Stainless wire is expensive.

Yeh just do alot of tacking to see what fits where and then at the end do all the final welding
