I have not uploaded it. The audio came out too muffled. I am trying to salvage it by putting it through some apps that boost the audio and see if it gets better. Otherwise, I am going to try reshooting the video next weekend. Looks like weather should be fine in Calgary next weekend so I might be able have another go at it.

Here is a short clip with not great audio quality, but it gives you a good idea about the sound of Invidia at full throttle. My windows were completely closed, but the audio quality is not great because my POV camera does not filter out noise well. I will try and see if I could put together a longer video, but audio quality might still be an issue.
I also was having traction issues because my tires are less than 40% left. You can hear chirps after every shift and also I peeled out off the line in my 0-100 mph run.

How is the sound on a long interstate drive? I just got my RCF and like that I can have a conversation at 70-80 mph. Wife gave thumbs up for an exhaust, so I'm just starting to look around. Want something fairly "tame" for daily driving. Tame in comparison to some other ones I've heard so far.
I have the Invidia cat back and spent 9 hrs on the interstate last week. The cabin noise was not an issue at all. I was listening to an audible book most of the way and had no problem following along at a moderate level. I didn't make any calls, but wouldn't have had any problem if I had. I drove in eco mode most of the time since I was just interstate cruising. Typical speed with 85-90. The tone is louder than stock, but not boomy or so deep that it resonates in the cabin. My wife doesn't have an issue with it. She didn't care for the ARK system it replaced.

Definitely like SoSlow said, this exhaust is loud when you want it to be on-throttle at high rpms and quiet when you don't want it to be especially cruising at around 75 mph in 7th or 8th gear. The piping is huge at 2.8 inches, but the high-flow resonators on the Invidia remove the frequencies that cause drone and the booming noises under overruns.

Me too. I was expecting the resonators would tone the exhaust for low cabin noise, but they basically tone it deep. The cabin noise was constant unless I kept the revs up. It wasn't obnoxious or terribly annoying, but always there. It had a more aggressive louder deeper sound that put a smile on my face, but I just didn't want that all the time.

Just wanted to add to this thread since there was some confusion on the spring bolts.
I found this video on Youtube showing the under body of the exhaust.
You can see that the spring bolts are not right after the main cats/headers. It's the normal bolts and then later towards the mid pipe you can see the spring bolts being used.
Hopefully this helps. I know Rolla mentioned it but sometimes it's easier for people to visualize it when seeing it in a video. I will be doing the install shortly once the exhaust comes in later this week.
