Never mention anything as such.
It was the OP's comment on the product.
FINISH: Full polished T304L stainless steel, beautifully welded together and finished off with hand made single wall stainless steel tips or premium carbon fiber shrouded tips

Ok Understood Alan. Thanks for the comment.
Do you know anyone using their product and complaining about that problem?
I did not see any unsatisfied customer on the forum (may be because I am new)

I can attest to the fact that, in the box, the valvetronic system is a thing of beauty. The unpacking experience is a bit like opening up an apple product - or at least back when I cared about what was in the apple box. Today....not so much.

That's what we were going for, in fact I think it was one of your comments in a thread a while back that prompted my request to R&D for this system. So kudos to you good sir haha.

I have not seen any video directly comparing those configurations in the same conditions.
What matters to me is more the quality of the sound and crackles rather than the performances themselves.
I must say that I am already very happy with the sound of the PSE with valves open, but I am tempted by the Fabspeed Race Competition exhaust as proposed. I would like only to assess whether not having anymore valves open/closed option would be still acceptable for street use (living in Europe).

It's no use for me using a heavier and more expensive exhaust with valves system if I always use my car with open valves and I do not intend (yet) to change the headers.

I think the offer from Fabspeed is pretty attractive if I opt only for the lightweight competition (race) exhaust system and keep stock all the remaining line. But I still have no idea of how much more insane would be the sound then compared to stock PSE in open valves position.

I would love to get an answer from Fabspeed.

This said, I still have no idea for comparison... between the Fabspeed Race exhaust and my stock exhaust in open valves position.
In case of doubt I could always opt for the Fabspeed Valvetronic exhaust system, but why should I pay almost twice if I do not need the "quiet" mode in close valves position and be penalised with more weight?
That would be double pain... and wasting money while I could do something else with it.
Sorry for the late response, been crazy catching up from the weekend haha.

1. Our Competition System is night and day more aggressive than the stock PSE with valves open
2. Our Valvetronic Exhaust System is not quieter than the PSE system with valves closed, it is mildly more sporty and aggressive in the valves closed position.

This system was developed for weight loss and the most sound improvement in a catback configuration. If you are looking for a reasonably comfortable improvement in sound, I would suggest starting with a set of our headers with the factory PSE. This Competition Race system sounds very much how it is described...a Competition Race system haha.

So if I had the race headers it would be too much for sure the same goes for a full-race (no mufflers or anything) with cats....but the sound would be glorious! Not sure about my neighbors loving it......
Completely agree with you on all accounts my friend

We also offer a conversation kit now for those who want to convert from our valvetronic system to our competition system and lose some more weight. Also, LOL at that dead rat.

In regards to the polishing, we have a massive polishing wheel that allows us to polish a full system in minutes to a beautiful mirror finish. As Jacy said above, you open the box and it is a "thing of beauty" or "work of art". For the little to no extra effort it takes us to accomplish that extra impression, it is well worth our time and effort. Same may ask why....well why not?

It just never seemed functional polishing the outside of a header.

Funny/odd story. We have moisture proof room under our deck that I use to store stuff like car parts. I had the OEM headers in a box wrapped in bubble wrap. Recently had some trouble with my aftermarket headers, so I grabbed the box with the OEM parts and took to the shop. Apparently there was a dead rat in the box when Evan pull the headers out. Poor guy.

Did the dead rat added any HP???? I have seen that before....I shrink wrapped the OEM headers and exhaust for that exact reason.....

Had to have been a solid 15whp, but only when coupled with green wheels and tire stickers

Without out getting into why, I unfortunately had to put my OEM exhaust back on. I have the valvetronic, and I assume it's similar in sound (I could be wrong) to the race exhaust with the muffler bypass on. The fabspeed sounds totally different than OEM. It's much deeper, growls instead of barking, much more like my RS was with no rear muffler. The OEM exhaust is very quiet with the bypass on, and only gets loud at high RPM, and even then, it's a higher pitch. I wish I had a video to show the difference.

This is with CG catt'd headers.

Sounds very nice, unfortunately many tracks will kick you out for excessive noise....

And so you would never run a race exhaust or header in those cases. I think the very removal of the muffler is an indication that you don't really care about those situations, or have a back-up exhaust option.

Glad I live in Texas.

I totally agree on this.....my car with headers and OEM exhaust had a higher pitched sound, very nice actually. We changed to a race exhaust but with race mufflers, it's louder and a deeper... sounds that's awesome.

Only track I would consider switching out my exhaust to meet DB limitations is Laguna Seca, other than that all the others I care about running out don't have any of those DB shenanigans. I mean Laguna Seca would be cool to run, but it's short enough I'll just take something else there....maybe the Miata just for ****s lol.

Couldn't agree more with you both in regards to the sound change with the mufflers in comparison to just the headers. Very well said!
