I pretty much went straight pipe all the way back. No cats, no mufflers, no resonators, only an x-pipe. Results are interesting and I'll be running it through its paces to see how it does, power-wise. I am finally able to get away from the last bit of LMS parts I had on this car (full turboback system), or should I say re-branded Corsa system, LOL.
A guy named Alex Gutierrez who has a shop named Big Head Motorsports. Super talented welder. Only online presence he has is IG, check him out at Big Head Cars. He does a lot of high end drag race stuff. And his shop is 3 minutes from my house...that was sweet! I'm going to tag him to do a lot of my future work, i.e., turbo manifolds, IC end tanks (since no one makes any IC for my platform), and maybe something trick with the intake system.
It's 3" all the way to a set of 3" bellows, then transitions to 2.5". There's an x-pipe right after the bellows and then out to the back and ends up with a 4" tip. Used 321 stainless on the test pipes as it retains heat better than 304 stainless, thus making the need for ceramic coating unnecessary. The system is 304SS for everything past the bellows.
But make no mistake, this thing is pretty loud. However, drone is non-existent at cruising speeds, it isn't raspy at all and has a good bass and tone to it. It's just LOUD when you step on it, lol. Which I don't mind so much.
Anyway, the quality of workmanship is out of this world. It's built for performance and maintenance will be easy with all the v-band clamps used instead of slip-fits and flange joints.

I used a GoPro Hero6 Black utilizing the on-board microphone and mounted to the vehicle here:
For the telemetry, I used the Torque Pro app and used a screen recording app on a small tablet. Editing of the videos was done only to get sound from the GoPro to sync with the video of the tablet.
