Check this link out also, it provides good info from Tony (Motordyne) on back pressure vs scavenging and how to properly engineer a dual exhaust system for the VQ35DE Engine.

You DO NOT want to sound like any of these sedans

A few points for you. First, know that I plan on doing a true dual exhaust on my sedan, and I have researched this.

1. This is not easy. The only half-way easy route would be to do it without resonators or mufflers. And that will sound like garbage, not to mention being WAY too loud and obnoxious. It's not a Civic, have some class

2. Unless you use mufflers and resonators, it will sound loud and raspy, like a fart can
The only exception to this is the True dual exhaust from Motordyne, but it's not designed for the Sedan, and is very expensive

3. No matter what way you do it, you have to move a bunch of stuff on the right side of the car, mostly, the charcoal canister. This is probably one of the bigger problems you will have with doing a dual exhaust on the sedan. The most common route is to delete the spare tire and install the canister in the spare tire well, custom job, of course. Plus there is a risk of gas fumes going into the cabin. legally, you cant do it, but people do.

4. If you are serious, know that you will NOT be able to do this job for less than $1000, and that's if you do EVERYTHING yourself, with used materials. That is also WITHOUT touching the Cats at all.

More likely, if you have to pay someone to do this work, it will cost you $2000 MINIMUM, probably more. And if you want it to sound good and still create power, without rasp and fart-can noise, it will DEFINATELY cost more than $2000.

For reference, I have about $1000 invested in my exhaust so far, and I still need to buy resonators, piping, flanges, hangers, rubbers, charcoal canister, hoses for charcoal canister, misc hardware, gaskets, plus pay a buddy to TIG weld it all up when it's ready.
I'm doing all of it myself, except the final TIG welds (because I dont' have a TIG).
That is factoring High Flow Cats and resonated test pipes on my setup. I'll probably be lucky to have the project done under $1700.

I thought I'd just unbolt the canister from its spot and relocate and adjust the hoses as needed.
then it'd be 300$ for the shop to install 2 mufflers and some piping with 2 dual exhaust upwards pointing tips.
damn was I wrong lol.

Really? a couple of decent mufflers would cost that much. Have you fixed your airbags yet?
