Anyone see this Speed Engineering setup?

Re: Anyone see this Speed Engineering setup?
I finally finished this. Took a long time and much tweaking for clearance. The key is to put the hanger in near the X pipe that attaches to the passenger seat belt through bolt, give a little more ground clearance.
the only thing I don’t like is that the exits points are not symmetrical so exhaust tips are not centered, but that is inherent with our cars anyways. I am just going to use turndowns.

Re: Anyone see this Speed Engineering setup?
Since posting above I have this exhaust and I did some extra fitment fabrication to hug the bottom of the car. I had many of the sections cut and re tig welded to hug my undercarriage. This was not cheap. I cannot emphasize this enough, as I turned a $300 kit into 4 digit custom exhaust. I have enough exhaust for anything but I am already considering going to a single 4". The drone in unbearable. I will experiment with some different mufflers but fitment is a major issue and I really only have room for bullet style.
Pros:
Leaves no power on the the table
Looks super pretty
Con's
Major expense if you want it to hug without scraping
DRONE

I'm in a slightly different situation, I have a turbo LS and single 3.5" downpipe I fabricated. I ordered this kit to basically only use the back half of it. My plan is to use a 3.5->3 merge into the two pipes. I do see some of the pie cuts you made in the back to tuck things. Interesting.
I have a 3.5" dynomax race muffler. I was thinking between it and the two mufflers in the kit, AND the turbo, it hopefully won't be too loud/drone.
I also have these SLP mufflers that they used to offer with their "loudmouth" kit:
The reason I didn't just buy the loudmouth pipes is because they are only 3". The mufflers are 2.5". I figure I could try the speed engineering with the bullet mufflers and tips and if it's too loud switch out to these SLP mufflers. The ones I have include the angled tips so the outlets are perfectly perpendicular to the rear bumper. But if I don't use them on this car I might toss them on my 4th gen.
Anyhow.. Interesting feedback and appreciated. I do like the way yours came out. Interesting that you used turn downs instead of the quad tips. Any reason?
Did you use the actual speed engineering kit, or the ebay one? I'm convinced they are both the same, but just curious.

Re: Anyone see this Speed Engineering setup?
As long as you have a something other than just cats and bullet mufflers you should be ok. I am going to experiment with a vibrant bullets and then may use a large dual in and dual out Magnaflow muffler in the same stock orientation. I didn't go with the quad tips because they just don't look right on these cars in my opinion. I wanted the clean hidden look so I used some cheap amazon 304 turn downs. I have them for sale if you want them. They are actually beautifully made given the cost and typical Chinese welding.
EDIT: I actually used the speed engineering 4th gen kit. Hence most of the fab work around the cats.

Re: Anyone see this Speed Engineering setup?
I can't even see your exhaust. That would be cool if I could hide the same on my car:

Re: Anyone see this Speed Engineering setup?
Ye the ground effects help. Without them you'd likely see the exhaust, maybe not the tips, since they are angled up, but right behind the rear wheel (from the side especially).
But in essence, mine is completely hidden, which is what I wanted.

Re: Anyone see this Speed Engineering setup?
Some mock up. It rests against the panhard brace. I may have the brackets to the frame for the muffler support wrong, I gotta look at some photos online.
I'm not sure if it makes sense to use the brackets that connect to the bumper mounts, they would hang lower than I intend on running the turn downs. I have some weld on isolated brackets I might just weld to the frame and the side of the mufflers once it's all tucked the way I want.
My 3.5-3" merge pipe hasn't come in yet. I'll probably get everything loose fitted before I start tacking things in place.
The tips look kinda neat but I think I like the turn down tucked look you did better. Maybe I'll keep the tips for my 4th gen.

Re: Anyone see this Speed Engineering setup?
Here is a short idle clip. The race muffler and turbo take some of the noise out of this. It still sounds like a performance exhaust, but you can actually hear my intercooler pump and fans over the exhaust in this clip, which is kind of funny and sad at the same time.
