    • Kline Innovation releases 2017 on Porsche 991.2 3.0 race exhaust with equal length manifolds/headers

      Kline Innovation is located in Romania. They do some great exhaust work and their latest release is for the Porsche 991.2 Carrera models with the 9A2 3.0 engine. Their system includes 100 or 200 cell cats as well as a cat-bypass option.


      Equal length manifolds
      100/200cell HJS cat pipes
      Test pipes
      Rear valvetronic system
      Carbon tips

      It is available in Inconel 304 grade stainless steel. The Inconel is roughly 22 pounds lighter:


      It looks great and it sounds even better in the video below.

      Why no dyno graphs though? A full race system with equal length manifolds should produce some very impressive gains.

      There is not a lot of manifold data out there for the 9A2 motor so hopefully someone tests it out.

      Definitely a nice option to have on the market.

        Sounds great!!! To be fair, I held mine in 2nd gear a tad longer and hit it hard in 2nd last weekend, in love!

        This one sounds pretty awesome.

        I wonder why they didn't dyno it? I want to know what those manifolds do...

        I'm surprised as well given they're major player in P market.

        Well, that makes sense...the car in the vid also has their headers. Thus, the sound improvement?

        I'm not sure what difference the headers make in sound. Would be cool to have a with/without vid.

        Straight from the source.... The headers improve mid range torque and also bring the sound in a more exotic area, which really changes the character.

        Still no dyno and couple hundred bucks more than Fab. I do trust their stuff tho. Definitely a nice option!

        I'm trying to get the dynos right now.

        Pricing:

        Valvetronic system with test pipes is 5080 USD
        Headers 2400 USD
        Carbon tips – 700 USD

        Don't post it on RL please ($#@! them). If you want link to it or just say it is on this forum.

        Haha, I asked them the same thing today!

        Assuming these have the same effect as equal lengths do on most applications when they are swapped for log/monolith style manifolds, they should definitely flow better, add in some midrange and upper end power thats probably going to be very noticeable when tuned.

        I dont think that there should be any low end spool up trade off, if any, with the lengths of the runners your seeing here.

        I don't think they are going to change the exhaust pulse timing enough with the swap to equal length runners to have any real impact the exhaust note. The elimination of the cats is whats really changing the exhaust note.

        Interesting. Fabspeed claims a spool tradeoff but I don't exactly consider them a high quality option.

        I've been trying to test out manifolds for a while now. Hopefully Kline gets back to me and I can get these on the dyno.

        Where are the headers/manifolds? Are they printed by Mimo? I'm holding out for Jonathan's stuff. Hopefully it gets released before I move on to a new car.

        How soon are you planning on moving to a new car?

        I've been trying to get Jonathan to make 991.2 manifolds... maybe @3DMetal can help on the topic.

        I'm not quite sure. Shipping my car to Honolulu tomorrow, starting a job there at the end of the month. Lately we have been getting a new Porsche every two years.

        Where are you seeing a spool tradeoff claimed fro Fabspeed? We are all guessing the performance impacts here because there's so little information from any supplier. Im kind of getting fed up with this nonsense.

        We have a product release, no images, no dyno's to prove any claims, no indication of the mods impact on driveability and performance.. a high dollar purchasing point.

        That is what they told me directly.

        Back on topic...

        I do not quite understand why all of the first to market products are based on the PSE exhaust. I know how the R&D process works and have made several marketing decisions when it comes to exhaust manufacturing.

        Makes no sense why they are chasing a market that has already spent $2900 for a PSE.

        The majority of these cars are leaving the lots with the sports exhaust, I think thats the only reasoning.

        Perhaps also, the people who are willing to purchase the sports chrono package are also more likely to spend additional money on performance than those who didnt go for the factory upgrade.

        The CBRD dyno includes bypass pipes, this is directly from them via text in September.

        I guess its fair to expect low end spool trade off on a manifold upgrade. The larger and equal length runner will flow better at higher rpms, but their increased volume and length from the collector delay the exhaust pulses from reaching the turbine as fast as the OEM manifold.

        The low end spool tradeoff may only currently exist with the current OEM programming, a little bit of timing, slight fueling changes and waste gate duty will negate this in it's entirety.
