Hey guys I have a G37XS sedan and I want to create a custom exhaust because I live in Canada and a branded exhaust system costs like 2k+ after taxes

SO I am new to exhausts, and recently did the dreaded muffler delete (never do it unless u dont care for drone; sounds decently good however..) and I was thinking of creating my own exhaust system that wont drone and is only loud when you step on the gas a little bit.

I provided a diagram (taken off google, this ones a G37 coupe) just so it's easier to understand and visualize and need some help choosing what to put for these areas. I'm going for a 2.25 inch exhaust system with the 11385 Magnaflow X pipe muffler (which I doubt really makes it that much quieter but tell me about it if you have this part)

I was trying to kill drone after my muffler delete and didnt really think of building a full custom exhaust until a little bit ago so I bought these two 1140 Ultra quiet vibrant resonators and Im still deciding where to put them.. either B (replace old stock OEM) but they are quite large so I dont know if it'll exactly fit yet (gonna check it out in a couple days), and if it doesn't i'll have to throw them onto A where the mufflers were.

SETUP (A&B will be switched around if it FITS)

A - 1410 12" ultra quiet resonators
B - 1791 18" or 1790 12" vibrant resonators (might go with 18" to make it quieter and perhaps remove more drone?)
C - 11385 Magnaflow X pipe muffler

TOTAL COST IN CAD
A - 300
B - 150-200
C - 165
Labour - 200
= 815 - 865 ish ; maybe more for labour/pipes


SO I do have a few questions :

1. does the placement of a resonator matter for drone? I've been hearing that up the midpipe (B) is the best to put your resonator to remove drone but also heard that (A) works as well?
2. do I need a muffler in the rear(A) ? these ultra quiet resonators are thick ASF and I think it might just do it
3. should I get entirely new pipes from the shop? or just try to work with the stock pipes and weld it on?
4. do i need flex pipes?

Any advice, suggestions and help would be greatly appreciated!

You want the resonators as close to engine as possible.
If you can spend the extra $$ get new pipe.
Too bad your in canada,I have a set of 12" vibrant resonators i used to have on my sedan.

Where in Canada are you ? I went to Mister muffler and for a whole new stainless steel pipe they were asking $2500 starting from the y pipe to the end so I decided to drive to Toronto and got an exhaust from a garage and I only paid $350 including installation.
