Water/Air intercooler setups?

[SINNER]

I like the easy way out. It worked well. I got the pipe back today from powder coating. Welds did not go great the first time because of no Co2 ran out. If you would like to try welding with no shielding gas go ahead. I went with the boots because they where easy. but i still have to add another cooler between turbos so would making hard pipes at this time make sense?
I is always easy to critisize somone elses work. Why not do the hard thing and give some advice.

Like was stated before, Weld up some mandrel bends in place of those silicone 90's for starters. The displacement from pressure on those 90*'s is going to back them off and cause endless headaches. Your not dealing with gasser pressures on that truck and the 90's are known to fail in a diesel application. Use straight boots and the ends of your pipe you can wrap a piece of filler wire 1/4" from the end and tack it to the pipe. It will work better than even beading the pipe to keep it intact.If it still dislodges it's a simple matter to make some retainer straps from the pipe to the cooler or intake.
