Vektor Headers on .2 GTS, install and quick review

Quick update, just had a chance to record some sound with the headers. Some key differences -
- overall the car gained a lot more boom and deeper throaty sound
- its a lot less muffled compared to stock PSE
- a lot more spooling sound (not the turbo whistle you get from the sport cats, but the sound of the car sucking in air)
- overall very happy with the sound improvement... a lot louder and very different tone compared to stock based on my memory
- in person, with the windows down, some times it even surprises me how loud it can get
but you can be the judge! on the low speed driving part, no crazy accelerations. stayed under 50mph and 4k rev the whole time... which made the most difference IMO
its hard to capture sound in video vs real life... but for your comparison, i found this the most comparable cuz you can hear a lot of similar tones but just more of everything with the header upgrade

That sounds tremendous! I like the change in terms of growl, tone characteristics and volume - the only surprise is just how much more pronounced the intake noise has become. This is precisely the sort of clip I was searching for when researching header impact on sound.
Looking forward to our Vektor vs. Kline header head-to-head!

Sounds good. Sounds like what this car has needed from the beginning. Nice job to all.

We are planning to have our cars dyno'd at the same shop on the same day with his car only having the header swap first. So stay tuned for that!
@Needsdecaf my thoughts exactly! and now seeing the 992s are coming with "upgraded headers", i think porsche really cheaped out on the 991.2 cars. Big missed opportunity in terms of performance and sound IMO.

Haha yes!! For everyone else, medtech and i live around the same area. He's looking to get a full set of inconel of kline headers + exhausts for his upcoming GTS

What I would really like to see is....
Test a Car with Stage 1 and Then Stage 2 (Just software - Without the bolt ons)
Then bolt on the Headers and test Stage 2 with Headers. (Because headers are meant to have Stage 2 Tune. ) That way you should see really what the headers are doing.
I know it really doesn't matter what gave you the power - Stage 2 or Headers when you have both, but interesting to see. (COBB will probably say, Don't run stage 2 without exhaust mods like headers and or Sport cats.)

I don't think they cheaped out on the 991.2 cars. Certainly they put some good $ into upgrading the suspension over the 991.1. And Porsche seems to be a very iterative company. That's the first go at the turbo carrera engine, and I think overally they made a pretty good product. It's too quiet, but it's not as bad as some turbo engines are, TBH. Just quiet in comparison to it's predecessor. But the way it drives is very good, and that's much harder to fix than the sounds. Or maybe not much harder, lol.
I traded a 991.1 C2S for this 991.2 C2S, so im pretty familiar with both. I didn't like the. 991.2 at first, being biased towards NA Porsches, but this one won me over.
Porsche did not cheap out on the 991.2. The TT 3.0 costs a lot more than the 3.8 NA motor. And the results are clearly worth the 3% weight penalty for street use, with 5% more Hp and a very broad 13% higher torque curve. Torque is everything for American street & highway use. My 991.2 was much faster than my 991.1 even b4 i put the X51 on it. Altho i have PDCC and RAS on this one, the handling even in the softest comfort mode with SC off is far superior to my 991.1 in Sport+ mode, with the same OEM Pirellis. And the brakes are clearly better. The intake sound is better. The exhaust note is not as good but is decent with the sunroof tilted up. I'm reading the exhaust note is much better with the exhaust mods. But I'm waiting for more empirical results b4 my decision on which exhaust stuff to buy. And whether you are looking at 7.6 or 7.1 lbs/Hp, this is muscle car territory - especially when you consider the higher grip the 991.2 tires have.

Nice job, been there done that on another car took two days and long nights for other reasons. The O2 sensors were stuck.
I read the entire thread nice discussion.
does anyone make headers which sit lower than Vektor? I am looking for minimum ground clearance.
because I really don’t care
... 1/2” really...try keeping an eye on the road and avoid going over stuff you should not be.

Could you take pics of the runner entrances and inside the collector?
