Default Muffler delete

So, I just did a muffler delete on my 2013 impreza 2.0 5speed hatchback. I did the whole thing by my self, from cutting welding installing, etc. I used an exhaust flange to keep the original muffler intact, so ultimately it became a bolt on. I will try tú upload a video a little layer when I get home tonight.
Well I liked it so much, I was wondering if anyone else would be interested, I am not selling anything here, this is just for research purposes, I liked it, but it sounds different from the video than it does in person. I would like to do the work for free, in exhange for a true review, you would have to pay for your own materials, like I said I am not selling anything. Just research purposes only, inbox me if you are interested, I live in el centro California.
So, if you are interested hit me up

Well, I guess you can send me pictures (with and witout muffler) of the under body, measurements, I am really good with math, so you can send a very specific blueprint of what you think would work for all sedans. I mean very specific blueprint, if you can with angles, parabolas, and what not.

I would think that this will effect the MPG and power a bit?? In a bad way...

The power might be up a few hp... MPG shouldn't be changed a lot, maybe a little lower.

Everything is a balance, more power, less MPG's, or viceverse. I would say you lose backpresure, but at the end, the diameter of the exhaust is the same, unless the oem muffler bottlenecks somewhere inside, the backpresure sould remain close to oem, I understand the air travel distance is now different, so that would be where the back pressure holds in, but like I said, it would be minimum. But yes, everything is a balance, loose some, gain some.

I am still working on this device, I made one with a different curve and lenght, it end up being slightly louder, but with a little bit of drone, slighlty noticiable, but louder. I will keep making experiments to see what gets more attention. I don't think the mic would pick up the difference, so I won't make a video of this one.

I take suggestions, I'm your builder, what do you think?

I'll do that when I get a chance. The sedan requires very little. Just a short 90 degree bend and about a 16 inch piece of straight pipe.

I just drove over a mountain, there is an area where I always have to drop the gear from 5th to 4th, to keep driving at 75mph. I didn't have to do that this time, I don't know how much more power I got, but it was enough to make my driving easier. I was waiting and waiting and waiting for the power lag, and it never came. I was impressed and very happy, probably better passing over power too.
