Hello I'm wanting to redo the compounds on my VP truck .I was going to build a side by side setup and was wonder what size tubing is everyone using on the hot pipe from turbo to turbo?
 
I would advise against side mount. I was wanting to do the same but I'm going to go traditional over/under since it's just more efficient. No reason to have the hot pipe as long as possible just to lose much needed heat/energy and have the cold pipe as short as possible where the opposite is true. Just a thought.
 
Don't have the pipe balloon leaving the primary only to neck back down at the secondary. Stainless steel will greatly aid in keeping the heat in the exhaust-gasses.
 
Your piping size is dependent on your turbo choices and the amount of fueling you have on the table. I agree that over and under for a towing setup is the way to go vs side by side setup. More info on your complete setup would help us all out on piping size if you must go the side by side route or even a over and under setup.
