OP states that he has a GTS, which is a gen. 2 car only.
GTS did come with the power kit, but gen.2 power kit retained the base/S exhaust header.

Hey guys, I wanted to chime in as i've had a few 997.2 GTS's come through the shop for our Sport Headers and they are quite a nice upgrade. Better throttle response, more pull throughout the curve, and the sound goes up a notch and becomes a bit higher pitched and exotic as you progress into the higher rpms. To this day my favorite sounding 911 to ever come through our shop was a white 2011 GTS that received our Sport Headers, X-Pipe, and Competition Intake. It is top on my list to add to my garage in the future.

If anyone is interested in a set of headers or anything else for their GTS please don't hesitate to reach out and ask any questions you may have. For reference we use the highest quality HJS 200 Cell Cats from Germany to ensure proper longevity of our product for Porsche applications

I noticed from the pictures on your website that the headers seem to hang a bit lower than the OEM ones. I don't know if the pictures are accurate and/or the ones on the site were a prototype design or the final design (the installed picture seems to have a lot more welds than the other pictures) - would you be able to clarify? On my OEM headers they have some indents in them to presumably increase ground clearance and I still noticed they were slightly scuffed indicating they have indeed hit something in the past... wondering if this would be a bigger problem with headers that extended farther lower than the OEM ones.

You have a very keen eye! Not sure how that slipped through the cracks but you are correct, that was a development set on that car which was never released. The set we did release and now offer perform much better. Just took that picture off the site, tip of the cap to you

We've sold more 997.2 headers than I care to count, and I have yet to have any clearance complaints. I mean don't go 90mph over a speed bump or through a dipped intersection and call me to complain you dented your primary tubes lol, but again i've not had anyone have issues because no one does that.

Bump - would love to know which brand of catless headers to pair with SW bypass on my GTS.

I have a GTS as well and am on the hunt for a new exhaust setup. BUT...I am really interested in weight savings and performance rather than sound. The Akrapovic titanium setup looks great but at $7500 for just the mufflers its very cost prohibitive. I have the Sharkwerks x-pipe with my sport exhaust and it sounds great! And a bit lighter too. So here is my perfect setup:
Full Titanium system with titanium mufflers and 100 or 200 cell cat titanium headers

Some questions:
Is Titanium too brittle to use as headers?
Does anyone make a full Ti setup?

I am willing to mix and match a system as long as the parts are high quality.

I have looked at:
FVD
Akrapovic
Agency Power
GMG (Where my car is currently for some interior mods)
FabSpeed
Borla

Generally pure titanium is not good for headers as the heat can make it go bad. But an alloy of it mixed with other metals can take it. Thats why most headers are stainles steel. With thin wall tubing they can be pretty light and durable. You could get into exotic things like Iconel but thatĺs really pricey. Probably best to talk to vendors to see what allot they use.

biggest flow upgrade will be from merge collector on aftermarket headers...u can go catless with a real race header and mini cats to avoid the cell..then just put the stocks back for emissions check..

if not just get some headers with 200 cell cats and power should improve since a restriction right at the header kills scavenging..

recently switched out my GTS' X51 headers with the Fabspeed headers and 200 cell cats. The new headers/cats seamed significantly lighter than the stock X51 set up. I didn't notice much of a power increase, but the it sounds waaaayyy better, IMO
