Porsche 911 (991.2) GTS - Soul Performance Exhaust Manifolds & Cat Bypass Pipes

[@artemusifasuenshuffleman8535]

Dreaming...I absolutely love this car.. 991.2 Carrera GTS upgraded (after market suspension, tunes, and the potential power) is becoming the cars many porschephiles have been dreaming of...A Komfort GT2..Wow!..+ with a manual transmission it becomes a GT2 touring....Targa Turbo S? No problem with the GTS4 it can happen ( a 4S would also). Speaking of S, how about a C2S or Carrera T narrow body built, paint it yellow and hang on.. The 991.2 carrera line up was, and still is amazing.

[@performance_engineering]

Thank you 😁👍 Yea the GTS is a brilliant motor and the upgrade really do take it to the next level. A GT2 touring could be a really cool motors. Do like the narrow body Carrera T but can't beat a wide body 911 😁👌

[@matthewcompton8877]

Work of art right there. Loving the new parts 👌🏻 sounds like it should now!

[@performance_engineering]

100% looks so nice 👌 shame it's not on display lol

[@BIueDreamm]

Can’t wait to get my hands on one of this GTS!

[@performance_engineering]

They ate great cars the GTS, sure you will love it

[@jeproperty]

This car is insane 😍😍 What a difference in sound, sounds amazing 🔥🔥

[@performance_engineering]

😁👍 Agreed, ace motors. Incredible sounding engine now too 😉👌

[@financeunchained]

So tempting to add this to my almost identical car!

[@performance_engineering]

You will live it, brings the car alive 👌

[@financeunchained]

@@performance_engineering did you ever dyno it afterward?

[@performance_engineering]

I didn't I'm afraid. I wanted to but had an offer to purchase the car and it went straight away. Was doing low 6s on a 100-200kmh which is around 991.2 Turbo S pace so went well

[@financeunchained]

@@performance_engineering wow!

[@stance4life.98]

Sounds lovely

[@performance_engineering]

Was a great sounding system 👌

[@RootsDaughter41926]

Great video, not sure but I think my ears could hear a whistling sound with the SP exhaust that wasn't on the old one (like a plane taking off).

[@performance_engineering]

Thanks 😁 Yea there is a small amount of turbo noise with the stock PSE but not its a lot more vocal 😉

[@Freshwilliams126]

That 911 sounds good. Damn

Sounds the business, I person it's just savage lol 😁

[@BrianStDenis-pj1tq]

Really enjoyed it, thanks!

[@BrianStDenis-pj1tq]

I don't see a dyno run with this combo yet. Can you do one?

[@performance_engineering]

Glad you enjoyed it

[@Caesarscars]

Sounds great. Definitely keep the PSE if you don’t want any drone. Cat by pass is the way to go in terms of raw sound.

[@performance_engineering]

Cheers mate. Agree with you there on the raw sound from the decats, I love it 😁👌

[@RandomYogi007]

Not familiar with terminology.. Could you provide a brief explanation? Im waiting for my new GTS to arrive and already know i want a little more airflow for turbos and sound out of the exhaust, but don't want to add droning, or make the closed valve sound too loud to where i cant enjoy my music. Thanks for the help!

[@LightwerkzGlobal]

@@RandomYogi007 Once you switch out the stock muffler you usually end up having drone. PSE is the Porsche Sport Exhaust option.

[@BensOutdoorExperience]

Awesome!

[@performance_engineering]

😁👍

[@lewiselliott9624]

Sounds savage!! Love the little turbo whistle you can hear now. Need a spin when shes tuned :D

[@performance_engineering]

It is savage Lew, you need to hear it in person. Haha yea them little turbos are happy whistling away now, love it lol. Yea don't worry as soon as its ready I'll be over 😁👌

[@theferrarireview1434]

@@performance_engineering Thanks for your great vids. I wanted to know if you are getting engine management light coming up? I fitted the Soul performance decat downpipes on my GTS and had O2 spacers but have the light coming on. It was reset when installed but came back. Any help much appreciated!! Cheers

[@performance_engineering]

@@theferrarireview1434 Hi. I tuned the fault codes out for cat efficiency. Usually running lambda spacers stops the EML coming on. Do you have the fault code which is coming up as you may have a damaged sensors during install which is very easy to do

[@theferrarireview1434]

@@performance_engineering Appreciate the help. I'll check fault codes and comment back at the weekend. Thanks again!

[@theferrarireview1434]

[@rubioalejo]

Great video! I have the curiosity on how you mount cars on that dyno ! Do you use ramps?

[@performance_engineering]

Thank you. Yea that's right, have portable ramps for the dyno 👍

[@goranjakopanec2289]

Hi buddy, from owner of the same car🖐️it's nice ti sed someone to tune the car like this 👍just courious are you having some check engine light becouse you don't have cats any more? And will you go now tuning it? Thanks

[@performance_engineering]

Hi Goran. There is 2 solutions to stop the EML coming on with the decats. First is to map them out in the ecu software, second is to use lambda spacers on the secondary lambda sensors, both should work 👍

[@solemods5991]

Did you have to map the ecu when you removed the cats?

[@performance_engineering]

Hi, removing the Cat efficiency fault codes within the ecu when cat bypass pipes are installed is best via removing the code in the ecu software but you can use lambda spacers on the secondary sensors but does not always stop the EML coming on. Hope this helps

[@norevlimitr1602]

Do you get any exhaust fume smell when driving with the windows down?

[@performance_engineering]

Hi. Personally it wasn't strong on the exhaust fumes, couldnt smell anything with the windows up or down

[@Posyworlwide]

I’m subscriber 880 , 8 is the number wealth. Let’s go 😅

[@performance_engineering]

Haha I like that 🙌🙌🙌🙌

[@trentmeister6001]

bro that final downshift

[@performance_engineering]

Sounds amazing 👌

[@billy991.2]

Really nice sound! How many PS and torque with this modification?

[@performance_engineering]

Does sound great. Annoyingly I didn't retest the system on the dyno before I sold the car but I can say it was around 0.2s faster 100-200kmh time

[@allenvaughn5410]

Are there any check engine lights or ecu issues with the catless downpipes?

[@performance_engineering]

Hi. Yes the EML will come on for cat efficiency when running the decats so would require them to be mapping out from the ecu.

[@aspavingllc8302]

What kind of power gains you think you picked up? Is it noticeable far as acceleration? I ha e same car with a tune bmc filter I’m more interested in performance vs sound and was planning on doing soul high flow cats with headers

[@performance_engineering]

As a bolt on upgrade only there is not a big jump in performance, noticeable improvement on initial response and doesn't fall flat up top. Because this ecu is a torque based ecu, once the software is adjusted to take into consideration the added hardware (stage 2) I do believe there is some brilliant figures to be achieved over a stage 1 tune only. Will get it on the dyno very soon and do a updated vlog on this 😁👍

[@turbocharged9589]

​@@performance_engineering any updates?

[@performance_engineering]

@@turbocharged9589 sadly sold the car im afraid and never got a chance to dyno the car with this current setup

[@turbocharged9589]

Why leave the OEM silencer?

[@performance_engineering]

OEM rear silencer helps maintain the refinement with no drone. The main restrictions in the exhaust are pre OEM silencer as well

[@turbocharged9589]

@@performance_engineering Ah, gotcha. It's just not as pretty as shiny pipework.

[@performance_engineering]

@@turbocharged9589 lol thats true. You may be surprised to know that the rear silencer was brand new at the time filming this vlog

Well shit. It sounds good. I have a soul downpipe on my 718 gts boxster and I love it.

[@performance_engineering]

Oh I love the 718 GTS. Bet that sounds the business now 👌

[@aaronbell5743]

Any check engine lights?

[@performance_engineering]

There would be but it gets mapped out in the ECU software

[@aaronbell5743]

@@performance_engineering Yep, I'm just not sure about a tune yet. Still have years worth of warranty. Dealer not tune friendly.

[@performance_engineering]

@@aaronbell5743 understand you want to keep the warranty. Another option would be a lambda spacer, should stop the EML coming on

[@aaronbell5743]

@@performance_engineering I have 2 of the ones that look like elbow macaroni, couldn't think of anything to call them. ha. They are the rounded 90 degree ones. I'm assuming use the one with the smallest diameter hole? Would you suggest these or another type? And what has your success rate been using these? Thanks

[@performance_engineering]

​@@aaronbell5743I personally don't tend to use lambda spacers as I map out the cat efficiency codes in the ECU but any spacer should work though

What part is the OEM silencer?

[@performance_engineering]

Hi. The cats have been install back on the car and sold now but believe the part no. Is 9p1254400A

[@yahomu3529]

That's a great exhaust sound! I have a question. Did you get an engine check light? If it happened, how did you remove it? I'm curious if there's a limit to the output of the car.

[@performance_engineering]

Hi. Thanks, this exhaust setup does sound brilliant. Running cat bypass pipes will bring on the EML which will require either ecu mapping to code it out or another solution is secondary lambda spacers, mapping it out is the best option. The EML on has no effect on the cars performance

[@Skendo2326]

That sounds the absolute dogs fucking danglies 😍😍😍

[@performance_engineering]

Haha good way to put it 😆 sounds even better in person 😁👌

[@danieledes1226]

This setup I guess wouldn't pass the mot?

[@performance_engineering]

You would require sports cats to pass an MOT emissions tests.

[@justuskarlt8625]

Valves closed had more DB as valves open lol

[@performance_engineering]

Believe its down to the tone being high is maybe why it gave a high reading. In person the sound difference is a lot deeper and volume is greater with them open

GTS is for the GT3 what a 370z is for a GTR
