You were joking about it being an EMT vehicle, he said it's an ice cream truck. Rather than go with the joke, he had to ruin it lol.

Re: exhaust question?

Header sizing and length is where your power is.

All you want the exhaust system to do is get the gases out with minumum backpressure
2.5 pipe is good for 450hp (in theory). mufflers will make a difference too. Use a mandral bent system with a straight through muffler design such as the Dyno Max Ultra flow. Mandral kits are no more money that a muffler shop kink job

Mandrel bent exhaust systems are the ultimate step in performance. Mandrel bent pipes don't lose any pipe diameter in bends, which means more flow and more overall performance. Having a full mandrel bent system also makes your vehicle's powerband more tuneable.
