Yeah, when you look at them side by side, the choice seems really obvious, even if a few hundred bucks more. With that said, I'll stick to my original comment, both would be a win as a final choice. Although, I still find it funny that you can't find a customer example of someone buying the Tubi Style on this forum. I may have to take the plunge just to prove a point!
I think Tubi is Italian? A buddy with a F355 has their headers and exhaust. I think they cater mostly to the Italian brands. Kline is Romanian but I think they made their name in the Porsche market first before doing some other German makes. Vektor, Soul, Sharkwerks, and Fabspeed are US based and Rennlist is heavily US user based.
@3point6 I invite you to give us a call to chat about all of your options for your 991.2! If you have a base non-PSE car changing out the cat sections / headers won't make a dramatic difference in sound to where you would regret it. There is not much weight to be saved by replacing the cats as most HJS HD 200 cell sport catalytic converters will weigh around the same. Our rear exhaust will shed less than a pound, but the anti-drone tubes are engineered to target and reduce droning frequencies that resonators cannot mitigate as effectively. You can also upgrade to a BMC air filter for a slight increase in intake sound.

Mike, appreciate the offer, will try to find some time and will visit later on, thanks
Everyone loves the headers they have, regardless of brand... I have no experience with Fabspeed but they are the only brand with threads I am familiar with containing testimony of fitment issues and less than optimal customer service. FWIW, Soul is the cheapest and the most praised customer service. That itself does not make them the best (or Fabspeed bad) but I think this sums up any knowledge transfer from searching.
My opinion is a little different than most here. Are you doing the install? I'd go with the best quality you can. My opinion is go with Vektor for headers and FVD for sport cats on a 991.2. Will you likely be able to tell across brands for the street? Doubt it. Is there a shop that you use? If so, I'd stick with their recommendations to help them, their relationship with the supplier and yours with them for the support.
thanks for your comments, i think it's a combination of a great product, perfect fitment and overall experience at the end of the day, even though i would like to install these myself, don't have a proper place as i used to, so most likely would need to have a shop do the install, my main goal here is not necessarily to make this car an S, GTS or else, it's a base carrera T which i enjoy and respect for what it represents so my interest here to achieve the lightest setup i can afford while keeping this upgrade as simple as possible

Ah, you have a T, lucky guy! Doing headers, sport cats, and exhaust may only save you around 20 lbs total. BUT, the headers and sport cats will accentuate what makes the T fun and that's the responsiveness. They will reduce spool-up lag and improve transient response making for a more responsive package. Plus, they'll improve the sound a good bit too.

good to hear that, if 20 lbs might be the weight savings, that would be appreciated, a little bit here and some little there (have AKRA exhaust waiting to be installed all together once i found the other two components), thanks!
If you go with one of the pipe style exhaust options, all in you'll get more than 20 lbs. I came from the Lotus family and weight savings is a thing for us. In my T, I got the CF buckets and rear seat delete (- 35ish lbs.), I also added the AntiGravity battery (- 40lbs.), Titanium wheel bolts (like a 1/4 lb. a wheel, I know silly), and I'm still not done.
I'll get custom forged wheels as soon as my rears need replacement (could be as much as 8 lbs. a wheel with HRE's, but $$$), and some form of 2 piece aluminum hat rotors when the brakes go (usually 1/2 to 1 lb. per wheel). Also, no sunroof for me. So, I already had a really light spec. even with my fatty PDK. All in, I could be down close to a buck forty when all is said and done.
HI it is not my intention to disrupt this thread, but if you want an video to get details and actually a bit of education (sort of a long video) you can watch this. If anyone has any questions PM us or email scott@ or chad@antigravitybatteries.com
Yes, Kline and Vector are the only two equal length headers, but thats where the similarity stops.
You missed the collector differences. We use a rotary collector to reduce uneven scavenging as much as possible. Any header with a flat collector will have different scavenging properties from outer-to-inner cylinders. Rotary collectors like ours, provide much more consistent scavenging of the cylinders. Hope you don't mind me using your pic to show the difference.
Also, another little nuance to our product (and a contributor to its cost) is that we use a cast collector. We do this for a couple of reasons. One, is that it opens up some design freedom in regards to optimizing the collector design vs fabrication. Two is that is eliminates welds; any weld is a potential flow disturbance and/or opportunity for a failure. Lastly, it makes for a much more consistent product from part-to-part. Now reason two and three here are more me being a nitpicky **** retentive engineer, and likely don't amount to anything anyone could ever measure in any for of real world usefulness. Reason one, while still likely amounting to marginal at best, is simply leveraging a process advantage the casting offers.

Did you ever weight them side-by side? I have not, but based on appearances, I would speculate they are within a pound of each other. Yes the 321 material we use is more expensive, Kline uses 304. For those that don't know why it's significantly more expensive, 321 is essentially 304 that has been alloyed with titanium to improve at temperature thermal properties. The alloying process is what makes it so much more expensive. My personal preference has always been to use 321 on turbocharged applications as it only does positive things for the long term durability of the headers. Also of note, Kline does offer these headers in more expensive options, even more expensive than ours. We do hang lower because of the collector design we use, but by far there are many other bits that hang lower on the car, and it's covered by our lifetime warranty. If you hit the header, you've got other, much bigger, problems besides replacing just headers :P
I would love to respond to your post, but the last time I did you had the moderators delete my comments and threaten to ban me. If the mods give me the green light I will disprove every one of your comments. Quite a bit of nonsense in there..
the cost difference between 304 and 321 is 54 cents per pound. CENTS not dollars. On a 30lb pair of headers the difference in cost between both grades of steel is $16. If that is part of the reason why your headers cost twice as much I think you need a new calculator. Let me also add that 304 has been used in headers for over 50 years without any issues. Porsche, Ferrari and Lamborghini don’t use 321 for their headers. You know something they don’t?
Man that pic made me spit out my afternoon java bump I'm flattered you think we'd buy by the ton in unprocessed raw stock. If memory serves me correctly, North America has 2 mills that produce 321 tube from raw stock. I have no plans for being number 3, but that would be one hell of a goal!
Here's a couple quick screen shot from a couple popular tubing suppliers showing a common size & bends in both 304 and 321. We don't buy or sell 'standard' elbows but this gives you an idea of the price differences and range.
Howdy fellow members, apologies if this has been previously discussed here; any (good and perhaps more important, bad) experience someone would like to share swapping OEM exhaust manifold/cats with fabspeed aftermarket similar? car is still under warranty and cannot deal with CEL (check engine light) or any other issues, more than trying to gain a few horses, I'm exploring reducing weight, appreciate any feedback, thanks
Hey 3point6,
Phil here from Fabspeed.
Thanks for the shout out. Any headers on the 991.2 should not give you a CEL unless they are made subpar and leak.
The cats are really where you are going to run into the most issues and pick up the most hp. At Fabspeed we use HJS and the biggest cat you can fit into the space so that they will last. I would love to talk to you about some options.
