I just listened again. Sounds even better the second or third time

Got the JCR exhaust installed last night, thanks to @4rings

Original setup:
Fabspeed catless downpipes and PSE with valves full-open mod from m-engineering stage2 + pdk tune (also have do88 turbo inlets and Bmc filters).

Sound:​​
Deep, throaty, metallic-y with loud lows and high’s. It sounded similar to a F80 M3 with a remus exhaust for those that might know about that, but more refined. Low speed revs were super growling and always present. Downshift rev blips were ear-gasmic. But interestingly only near the max high end/redline the screaming of the exhaust sound would lose a little steam and volume. Weird. But overall the valve-open mod totally transforms the PSE into something entirely different. Loved it and still kind of miss it; it’s still the best thing you can do for your car if not going with a high end exhaust.

Volume:
Very loud but not obnoxious. 9/10 inside the cabin. Loud presence inside the cabin, like the engine/exhaust was literally right behind your head.


New setup:
Same downpipes but now with the JCR valved exhaust. Keep in mind the valve-open mod from the tune is still there.

Sound:
Totally different than the original setup. Smooth(er), fuller, hollow, with a very distinct titanium-howl tone that really makes itself more present in its resonance as rpm’s climb and at the top end, screams with that horn/brass quality. Very bassy/pronounced at low end speeds. Downshift revs are crisp, can be felt, and sound glorious. No drone at all.

Volume:
This was where I was originally unimpressed at first drive; the average overall volume was lower than the original setup. There was less noise inside the cabin. But then my buddy did some wot flybys with me standing outside, and I couldn’t believe how loud it was. So the volume was very external I thought. But then I drove it myself again, and my ears/brain adapted to this new sound profile and I started liking it, a lot. The titanium “wail” is definitely there, and I feel like the volume inside the car is also more “present” than it was at first. I would say it’s 8/10 in volume inside the cabin at most speeds, but a 10 at the top end; unlike the original setup this one screams louder the closer you get to redline. You hear the exhaust as it’s really there at the back of the car, with bassy undertones inside the cabin. But it’s so addictive to chase the higher rpm’s because that titanium scream is intoxicating. Intoxicating inside the cabin. Overall it’s more of a hybrid now between exotic and a hint of (dare I say) formula car.


Other/final thoughts:
@4rings has an Akrapovic exhaust with Soul catless down pipes. We compared both of our cars, even drove both along side. They are very similar in their overall sound profile. The akrapovic may just be a hair louder, but it’s hard to tell. We need to compare more.

Overall very satisfied and thrilled with the JCR exhaust, and highly recommend it. I think it’s the best exhaust for the price, and I’ve researched all of the different exhaust sounds out there. I need to drive the car more (all of this was only from last night couple of hours of driving) to get an even better feel for everything. Also, I can’t say how loud it would be without catless pipes or atleast sport cats though; stock cats may not cut it. I also debated whether to get the non-valved non-silenced JCR exhaust version, as that would have been even more extreme. But ultimately decided I may still want to to use the valve function for silent mode drives (wife and kid smh). And JC was very responsive given the timezone difference, and answered any questions I had. Shipping was very fast from the UK.

Only have a couple of small clips from phone I’ll try to upload on YouTube. Don’t have pro recording equipment :/ , so of course it sounds better in person.
I am pissed, Redd! I got over $10k worth of new wheels a month ago and promised myself I was going to stop there. You are making that promise impossible to keep.
This sounds better than Akra, Soul, IPE and Capristo, in my humble opinion.
Congrats!

Titanium definitely has that edge. Realistically it sounds 2-3x better in person, phone vids suck. I’d say it’s equal overall to the mighty Akra. Glad I could help make things a little difficult for ya I’m in the same boat, I still want to wrap my car in chalk, another $4k lol

Here’s a pic. It’s a very clean and easy install, and doesn’t even re-use the oem muffler hangers nor does it have its own; it just bolts on to the cats (as seen on the far corner) which are sufficient to support its light weight.

Great review and description...no drone on my TT with the valved titanium and iconel race cats. Intoxicating is the word.

3rd day in and it’s unbelievably gotten even better and louder. If you’re thinking about an exhaust, do not hesitate!

Question. Did you keep your M tune to valves always open? Thanks

If you get valved it will be non silenced? I don’t see a valved, silenced configuration on JCR website. Not that I want that, just making sure I understand all of the potential configurations.

How would one compare the following set ups?
1. Race cats, valved, non-silenced
2. Race cats, non valved, silenced

Obviously you retain the valve functionality in #1, but assuming you drive 100% of the time in Sport or Sport Plus which of the 2 will yield a better sound profile?

Yes valved is non-silenced. That’s the one most people will get. It sounds the best in sports/+ and in manual mode.

Valved non-silenced will be louder than non-valved silenced.

I would ask JCR to chime in on this, as when I asked Jonny, I believe he stated the opposite - i.e., the valved, non-silenced exhaust will actually be more civilized than the non-valved, silenced exhaust due to retaining the valve functionality.

Nope. Those are the answers he gave me himself, as I had asked the same question. In order of loudness:

1. Non-valved non-silenced
2. Valved non-silenced
3. Non-valved silenced

During normal driving valved is very close to the silenced (non valved) centre however once you get into throttle and the valves open on the valved system its louder than the (non valved) silenced centre

The non silenced non valved system is the loudest under all conditions

Having valves fully open is a must imo, can’t get enough of it. Adds a deeper layer of aural pleasure in any exhaust.
did you notice power loss with the valves fully open? I heard someone say that they saw via dyno the power loss from this.
