Akrapovic OAP is the only Exhaust upgrade you need for 718 GT4 (+ more JCR fitment issues)

- here's my verdict on this topic: if you want volume, get OAP. If you want tone get JCR or Kline. If you want both, OAP (Akra) + JCR or Kline just hits the spot. Here's my video on JCR exhaust installation. There are fitment issues with PDK gearbox as I explain in this video: • Installing JCR Non-sil...
listen to the exhaust on track: ruclips.net/video/0E_Ssyf0e98/видео.html
the giggle when POV starting the car says it all. it sounds glorious, loud but I guess that is the whole point to it
exactly, its unreal how much more emotional the car can be by just changing the cat back exhaust
That was worth it, that sounds great, a lot better than the factory exhaust it's got a really sweet song now, great job.
thank you! appreciate it
Dude - absolutely fantastic combo ;-)
thanks man! it really transformed the car
Sounds amazing!
thank you chuck!
Great looking car!
thank you!
Thankyou, very informative.
thank you.
Amazing sound! Can you, please, do more onboard videos with this setup?
absolutely
Recently saw a GT4 for sale in this exact same spec, Python Green with gold rims, except it had carbon ceramic brakes with yellow calipers. It was a CPO car with a great price tag. I hate it I missed out on that one. I just love the green + gold combo...
Sounds amazing! Definitely looks like it pulls harder than a stock gt4
I have an allocation for a PDK gt4 coming in a few weeks but I haven’t sold my manual g80 m3 yet that has midpipe and intake. I’m worried I’ll miss the torque but I know I’ll gain something else that’s amazing with driving dynamics and that engine sound
it def did after the oap! congrats on your incoming GT4. Ideally you keep the G80 manual for daily and the PDK GT4 for track use but i totally get it!! I can tell you this, I had a friend who went from GT4 to G80 and he regretted it (had to bc he needed a family car). I am also a manual fan but the pdk is justt sooo good
@@blendlinegarage42 Thanks! Bummer for your buddy though.. family first of course, and the G80 is great for that all around car. Ideally yeah I'd have both, but also have an electric "daily" for more casual driving. I'm thinking with that OAP + BMC filter it should feel plenty quick...I've only driven 1 pdk and 1 manual GT4/Spyder which were both modded w/ headers + tune, so dont have a fair comparison for stock. We'll see how it goes!
Sounds great man. Would have loved a vid with rear OEM exhaust (box) still in place though... I'm thinking of only doing the OAP and leaving everything else stock.
thank you! check out zerintx on insta, he has similar setup to what you are looking for.
looking forward a comparison with the akra OAP but the OEM backbox
yeah hopefully I can find a local GT4 with a that setup and we can do a comparison. Based on all the videos I've watched online, the OEM backbox and Akra OAP sound deeper. With JCR exhaust you get a much higher pitched tone (due to titanium construction)
FYI - had my OTA pipes from SOUL coated in Jet-Hot Ceramic (lifetime warranty) and they look gorgeous with multiple colors to choose from...shouldn't be a deterrent for anyone who feels they need heat shielding. The fitment is perfect - especially with their back box. John from SOUL can hook you up!
I just looked up jet-hot.. very interesting! how much did it cost to get the SOUL OAPs coated?
@@blendlinegarage42 I opted for the 2500 Ultra Supreme (essentially double coated - since it wasn’t all that much more than a single) and it was around $500 at the time. I picked up my complete system during a Black Friday sale so the discount basically covered the cost of the ceramic coating.
Oh my lord! Been waiting for the full vid as I saw some clips on insta! Is there much drone with this setup? I know you are are quite a stickler for any drone...but this to me is the perfect sound for the GT4.
thank you! drone has not got much worse. Most of the drone was introduced when I installed JCR exhaust. with OAP it is a bit louder but not by much. The way to avoid drone is to keep above 3K RPM. I agree with you, it sounds perfect! I am finally happy with the sound. That being said this maybe a bit too much if you plan on daily-ing the car which I don't.
@@blendlinegarage42 Yeah, mine is not a daily either...track db limits in UK kinda suck though so that's my only real concern...having listened to videos where they do the headers too I think that gets too loud...so yeh, closest to GT3 sound is the setup you've got...I just completed break-in...so first few times getting up in the RPM range does sound pretty good from inside the car hehe...but I know I will need an exhaust
Fun for a day or two. After that the 100db drone would get old. I've had a few Porsches. I like em so i can drive them around town and to track days without changing too many parts. But maybe your tracks don't have noise regs.
thats why you need multiple porsches :) one for daily, one for weekends. also not much droning in this setup once you are above 3k which i am constantly when driving this car. Texas tracks (cota and msr) dont have noise regs but the ones in California do.
Hey there
I've got exactly same set up except that my jcr end is silenced.
The car sounds truely amazing.
Do you think you will be considering headers as well in the future?
As i get used to the sound i feel like i want something more.
I'm afraid it will make the car too damn loud even for me but if there's a way to make it just little bit more louder and acheive higher tone, i would definately get it.
I totally hear you and feel the same. Next mod for me is the BMC air filter which will increase the intake noise and give exhaust just a touch more volume. I will post results once I do that and perhaps do a dyno run with the new setup
Sounds perfect! Any attention from the Police so far?
I’m getting a GT4RS later this year. Manthey says Akra will provide an exhaust for that too. Just worried about warranty issues etc etc.
cops are pretty cool down here in Texas. The one time they caught me speeding I told them “I just put on a new exhaust and wanted to hear it open up a bit”.. he came back saying he will assume that I am still getting used to the new car and let me off with a warning! super cool cop. Congrats on GT4RS. I checked with my dealer abt my GT4 warranty and they said unless you are adding headers and/or a custom tune, it wont impact your warranty.
Great video!! I was wondering if you can point me to where you got the gold Porsche Race stripes? I see that Porsche normally does not offer this color.
thank you! it used to be a site called renndecal but sadly porsche threatened to sue them so they stopped printing them. I think you can get the porsche factory ones for 992 Carrera in aurum and they should pretty much fit 718s the same way. Also most of reputable decal shops can print these decals but matching color and details (like the width of the stripe) is hit and miss with some
Hey what driving gloves are you using?
Do you know why they aren't selling them to the US anymore?
Any issues with the studs? Obsessed garage guy struggled a bit with those. Are they all studs or are a couple studs or what? Thanks! Also do you find this setup a bit too loud in the cabin now?
yeah actually my friend who was helping me ended up unscrewing the stud instead of the nut. so we ended up using the double backing nut method (or whatever its called) similar to the obsessed garage guy. That being said the other nuts came of loose no problem. All of them are double side threaded studs. One end is screwed into the cat flange the other side protruding where oap gets hung on and then bolt goes on the threaded stud clamping the oap flange to cat flange. it is def louder but in a good way (to my taste). Only downside is drone with jcr backbox at around 2500-3k
Did you get the loss of horsepower back with including the OAP alongside the JCR?
It certainly feels like it, but I am planning to dyno the car soon (by mid dec) and I will know for sure. I also since have added BMC air filter so I feel the whole system is now flowing better.
@blendlinegarage42 - I plan to install a JCR OAP. Do you think I can perform the job with the following limitations?
1. Using mechanic ramp (backing it up to the ramp; not using jackstands)
2. Without removing rear wheels (since I'm using a ramp)
might be possible but you may have a very hard time reaching the nuts connecting the oap to the headers. specially the top bolt on the triangle flange
@@blendlinegarage42 I was afraid you were going to say that. Thanks for confirming though.
How about having the car smog tested to find out if it passed or not? I know you can always put back the stick pieces to get it too smog but if the catalytic converters are still on the car it almost surely will pass more than likely.
my inspection is due in a few months, but I know for a fact that OAPs won't impact the emissions. Cats are still there, plus the US bound cars do not have coating that actually traps the particulates.
Any issues with warranty you have heard from Porsche? I am a fellow GT4 owner from Vancouver.
The only issue you should have is with emissions. I'd call your dealer and ask them first they may work out a deal where they still honor warranty so long as you allow them to install the exhaust setup you'd just be paying the premium for porsche mechanics. When this is something anyone can do alone
How long did it take to make the change with the new OAP? Like the installation time ?
we ran into an issue with the stud coming off of the header. with that it took us 3-4 hours
I'm currently running soul race header, soul over axle pipe, and souls valved exhaust system on my 718 GT4. It's way too loud. When I get my gt4rs I'm just going to do the over axle pipe.
yeah i think headers and OAP are either/or. Together they are complete chaos
sounds awesome! how much were the OAP pipes?
Thank you! Akra OAP was selling for around $2K USD when they were brand new (what a bargain compared to other titanium OAPs like JCR). Unfortunately they are not imported to US so I bought it from a fellow GT4 owner for about the same price and brand new. The closest you can get to this on market is from Flat6 motorsport for $1.7K but those are made out of steel and not by akra.

That thing sounds nasty as fuck definitely the way to go with running an exhaust on this car it sounds good at literally all Rev ranges.... Readouts are based off a number of factors how the dyno is calebrated as well as temp altitude barometer etc. Also when doing these upgrades it may be wise to get a tune done to bring on the full effects of the upgrades even on a na car. Turbo car for example you do a downpipe intake intercooler piping etc you're not going to see any gains until you tune it.. I fact it may reduce the power until tuned... Also I understand it's frustrating but theirs nothing wrong with that plate getting bent as you tighten it down you're being way to nit picky about that. Also those high pressure clamps don't have anything that tells you okay it's too tight or tight enough so you kindof gotta eyeball it literally 1/4 turn too tight it'll snap
100% on everything you said. I figured I had to just stop at some point after tightening those clamps cause they would just keep going without much resistence.
Not many tracks here in the UK would allow that
what is the clamp you got from amazon?
AKIHISA 4 Pack 52-55mm ID Range T-Bolt Hose Clamp,304 Stainless Steel Heavy Duty Tube Clamp 2.05 to 2.17 Inch a.co/d/9TKl4kP
Any chance we could get a cold start?
absolutely will so a clip soon
does it throw a CEL without remap?
in US oaps are not sensored/monitored
I’m curious, why didn’t u go with the jcr link pipes?
bc they cost nearly twice as much and Akra is a very well know brand. I also had fitment issues with the JCR backbox and didn't want to risk it with them again
@@blendlinegarage42 mmm got it! It just more difficult to find a an akra setup for the moment.
Thanks for your comment
@@blendlinegarage42 does it get drone with this setup?
@@davidsalomon3348 yes drone was there before with JCR exhaust only too. its a bit more boomy now with OAP at around 1k-2.5k.. if you drive a bit sporty and keep rpm around 3k and above, absolutely no droning.
Why are particulate filters used in US cars?
based on what I've read, its due to keeping the part variation low and speed the manufacturing process. It seems the US filters lack the necessary coating to trap the particles and burn them off, making them absolutely useless both from emission and performance perspective.
I've gone with the Akra OPF delete link pipes, sounds perfect and got some great power gains via a remap - here is my video - ruclips.net/video/74qwy-z0sLI/видео.html
yea I watched that video when it came out! thats huge gain!! congrats! how does the car feel? where in the rev range do you feel the gains most?
Hi, has this set-up triggered a check engine light yet?
No engine light at all. This is NA car so the particulate filter is not equipped with a sensor.
@@blendlinegarage42 OK thanks for clarifying.
@@blendlinegarage42 Actually the US cars are not equipped with the sensor for the stock OAP's which is only a European requirement.
What color is this green?
python green
I can’t get this link pipe anywhere in the U.S. any advice brother?
look on ebay! also i am selling mine soon so stay tuned
@@blendlinegarage42 please let me know when you want to sell those. Thank you!
@@richardly438 took them off the car yesterday (trading in the gt4 for another car. I will be listing it this week. drop me and email and let me know where you are located: blendlinegarage@gmail.com
Please check your email.
Weight difference?
Akra OAP saves 9lbs, JCR exhaust saves 22lbs.. total weight saving of 31lbs
Why don’t they import these pipes to the states any longer???
This is the response I got from their US distributor: "Unfortunately, the over axle link pipes are no longer available in the USA since they are not CARB or EPA legal."
What about drone? thank you
yes from 2800-3300 is pretty boomy, but you can do down/up one gear and its all good. mostly an issue when you are crusing in 7th gear (pdk) but if you down one to 6 it goes away (at cost of higher mpg)
LMAO! Yeah.... That would annoy the Hell out of my neighbors.
"Uh-Crop-ah-Vitch" = Akropovic
It’s pronounced A -Krap -Ovic.
I don't give a-krap-on-which!
It’s actually a Kra po vich lmao.

Thanks for the video but plz oh plz lay off the hand gestures... Likes rubbing on everything and touching everything with the hands while talking. Drives me nuts. It looks kind of funny and not funny haha!
you dont have to worry, i only molest things that are made of titanium
