RS Speed Custom Titanium Exhaust?
So I've been shopping around and researching for an exhaust setup for my 991.2 GT3 RS and right now I'm looking at the JCR Superlight Inconel Headers and their Titanium Race Pipe, however I just ran into a company called RS Speed Design which apparently makes custom titanium exhausts for various cars. Their titanium exhaust looks pretty sick and sounds nice too. I searched on here to see if anyone is using or talking about this exhaust but i found nothing Here's some pictures and videos of the exhausts they make. I'd love feed back and opinions on what you all think of them. Thanks!

Not trying to be rude or dismiss you post. Unless this is significantly cheaper than JCR, I'd stick with JCR based on the quality of the construction and weld quality alone. I highly doubt it is much cheaper though.

Hmmm....I'm no expert but that's A LOT of welds for an exhaust....more welds = more possible points of weld failure.....would love for RS Speed to chime in with some more info.....

JCR's race pipe has a tuned length and a merge that promotes scavenging. there's way more engineering that goes into it. this is just a simple straight pipe that was thrown together. not saying it's a bad product, but I wouldn't buy one when the JCR is seemingly a way better product

Same sort of thing as the titanium race pipe from Sheepey. If I had to choose, I think the one from Sheepey looks like it's built slightly better. But it's not valved. The idea is that it uses Helmholtz Resonators to stave off drone.
I think these shops are getting pre-cut titanium fittings from Ticon Industries and welding them up. So you're paying for all the extra labor of welding a hundred tiny bits of titanium together. The welds on this RS Speed exhaust are also all those bright colors. From my understanding (which could be wrong), good titanium welds should be a uniform golden straw color. When you see lots of purple and blue it means the welds are too hot. But it looks cool and that's the trend right now. Sheepey and JCR both have really good looking welds.
JCR seems like the best option still.

Stick with JCR. I can't imagine that custom piece lining up right. And all those welds...

Or, you could just get a set of Dundon catted headers with removable cats. Later, add Dundon's intake parts for a well thought out 'system'. That's what I'm doing.

That speed custom exhaust looks terrible. Stick with the JCR race pipes. The loop design, x-pipe and titanium thickness, give it that perfect RSR sound. The craftsmanship is great too. I have a full review of it up.

The sheepy and speed custom designs don't have the loop design. They both give off that fart can backfire sound on let off.

And the backfiring is in the tune. Not the physical design of the exhaust parts so it's a moot point. You can make any exhaust backfire and pop by tuning the ECU. Or you can just install the exhaust on the car without tuning and get the same sound as any other exhaust.
BTW, the pitch of any set of pipes in any system (like a car or even a trombone or trumpet) is determined simply by its length. There's no magic involved. The longer the pipe, the lower the pitch. The shorter the pipe, the higher the pitch. Balance tube = sharper, more growl timbre. X-pipe = smoother tone but more rasp. There's also, theoretically, better scavenging with an x-pipe. But no idea if that actually matters when it comes to performance on a GT3/RS since the merge happens basically at the exhaust tips.

What is a "loop" design? Why is it "good" or "better"?
