dual exhaus. new guy question

Hey guys first off I'm new to the powerstrokes not to Fords.I recently purchased a 97 7.3 e4od with 4.10s. It is ext cab long bed. My question is that it has a 2 piece 3 inch down pipe to 4 inch exhaust. It goes to the muffler and cone out as a y pipe and than goes over the axle and out behind each tire. I would like to know if anyonr has ran dual exhaust one on each side of the truck.in front of the rear tires, and if so how they did it thank you in advance guys.

I have seen it done, but the exhaust system was custom built by a local exhaust shop. I do not think you would be able to do it with any kit you can purchase.

If I'm reading this right Viggy you are asking about a "true dual" exhaust? Like Justine said it can be done but its all custom and you would need double everything back to the manifolds. Two turbos, two mounts, two oiling systems, then two sets of pipes all the way back. Pricey but you will definitely be in a class of few.

If I'm reading this wrong and all you are looking to do is move the tips from behind the axle to in front of the axle then really just ditch the muffler all together, move the Y-Pipe forward a head over to NAPA and grab some 4" tubing and bends. Cut the hangers off the other system pieces not used and make a mount on the drivers side. Just remember that the fuel lines are over there and no shortcuts.

You could just shorten everything up and re-use the Y, it will be up to you to come up with the bends you need to get them to come out at the angle/location you want. I'd just lay the Y on its side instead of using it vertically like you do with the behind tire exit. Shouldn't be too hard to figure out so long as you can find some locations for hangers.

That would definitely be unique but im wondering if its even feasible only because i think the limiting factor would be the intake manifold. Theres only so much air that can go through in a given time and i would guess that one turbo is already close to maxing out that limit but ill bet it would drastically reduce turbo lag. Would be a cool build for someone with money

I don't think he is talking about a twin turbo set up, I think he wants his current duals in front of the rear tire instead of behind like they are now

OP... you could shorten it like said already, and you have to account for the movement of suspension and driveshaft because they may hit, as well as your front fuel tank, it would have to go under that as well

I'd just use twins off a 5.9c. They're pretty small...

To me the reason that you don't see duel tips in front of the tires is that the tube to the left side has to get around the d-shaft.

Ya that is what I figured the fuel tank and the ds would b a pain that is why I was wondering if anyone had pictures of it done. A true dual exhaust would be too much I just want my dual in front of the tires. Thank you guys for your help I'm just gonna remove the muffler and see where I can make up some hangers. Eventually when my broken ankle heals I will get around too it and try and snap some pictures my self.
