Ambulance Modifications

I already posted this in another thread, just lookin for some help.

Alright, I am currently the maintenace person at a small ambulance company ( I am a full time EMT their and maintenace is my secondary job), basically I do the oil changes, tire rotations and anything else that needs to be done. Anything major such as engine/tranny work goes to a shop. Recently the covering of the muffler came off and I asked my manager if I could replace the whole system with stacks on either side of the box, he said yes, which i wasnt expecting. I have looked under the vehicle and checked some thing out. I have seen that it wouldnt be hard to split the original tubing and start new ones that branch to either side, run up the side of the box and end in some stacks. So now im asking, does anyone know where I can get stacks and just a bunch of tubing so I can make an exhaust system myself, or some suggestions on what I should do, such as do I need to add headers and do I need to have mufflers on their. Anything else would be appreciated such as watch outs and any other pointers. My boss pretty much wants to make this ambulance a badass ride since right now its pretty gutless. So anything would be much appreciated.

I would ask in the truck forum because they have kits for trucks that should be easy to fab up for an ambulance.

Actually why don't you get him to allow you to put headers on the ambulance and a set of side pipes instead of stacks. I am assuming that this is a diesel since you want stacks. You will probably have less problems with the side pipes and you should be able to find them fairly easily. Search truck parts on the net although you may have to adapt them for your application. Back in my Paramedic days I always wanted to put hooker headers (ala mother jugs and speed) on an ambulance with a working hood scoop, tunnel ram and high lift cam. Of course all ambulances were gasoline powered back then. Would have been the fastest and baddest ambulance around. Good Luck!!!
