Sounds really good! Pretty smooth overall outside, I wonder if that's because you left the OPFs in? Just OPF removal makes so much more gutteral and harshness. I like what you did! What about the inside?
Yea… the camera audio did have me confused as it actually sounds better (on the vid) with the valves closed. Like you say… must be the audio as that certainly can’t be right in reality.
I tried again to capture more accurate audio this morning and failed again 🤣. The DJI microphones can’t hack it even with the gain set to -12db I’ll find a better microphone and manage it somehow! In reality it sounds very much like the Kline or JCR exhaust ✅
It’s a lovely clean tone but sadly there is a small bit of drone at around 2k rpm and high load. I generally don’t find myself in the drone spot so it doesn’t both me luckily 👍
I have a 2021 4.0 spyder. I did headers, oap with 200 cell HJS (no CEL) cats in the location of the particulate filters. In sport mode its pretty freaking loud with the stock muffler, as loud as I would ever want it, and still respectfully quiet when not in sport. Only thing I am going to do is a tune, not so much for the power, but to fully control exhaust flaps, and turn off cylinder deactivation which is super annoying...even worse with free flowing exhaust.
It seems that they are the best options, either stock headers with opf’s and a aftermarket rear section or aftermarket headers and opf with a stock rear section. Only problem with the stock rear section is that the valves are annoyingly noisy when they operate at various low rpm, as you say a valve controller or remap to set to fully open/closed is the solution.
Proper sound that now, well done 🎉
Cheers, there’s another video showing the sound better 👍

I’ll get a video of the inside but in honesty it’s so hard to capture as the induction noise is so loud (there’s a video on the channel of that too) 👍
I’ve got the same exhaust on my GT4. Recommend the exhaust valve controller. Tempted to lose the OPFs when the warranty expires
It’s a mega exhaust, I can’t seem to capture the sound properly on camera as it sounds much better in person

How are you liking the exhaust after a few months, does it drone or does it have a clean tone at lower revs ? Welcome any reflections !
