Straight Pipes - Lightweight Performance Exhaust of Porsche 964
Вставка
- Опубліковано 27 лип 2024
- Full of energy after a quick summer break it's time to get straight into building my new exhaust system. With a few turns back and forth I found how to make it all work in the setup for my car and how to make a lightweight performance exhaust!
Note: Be aware of my TIG skills!

Great work! Very nice of you to give Phil a shout out; his channel is actually how I found yours. Been subscribed ever since. Cheers.
Jonas,
When you are tired to be in your man-cave please write a list of your new motorparts so we other can try to catch up with you on the next tribe meeting.
Its so relaxing to know that you have tried out the best… In my case i have a 964 - with many miles - which need a heavy upgrade to 3.8 L!
Thanks for the best UA-cam channel - by far!
//Peder
Garrett and Precision make some great exhaust silencers ;-)
Love it how Phil from DW was advised to watch the vids in your channel and then he binged them! He did a nice shout out for you and it's great to see the same from you Jonte. :)
It’s really fun with some enthusiast driven global collaboration!
Yours is actually one of my favorite projects on UA-cam, I get genuinely excited when there's a new episode. Also good stuff shouting out Phil, he's how I found you, hope you guys can collaborate on some stuff.
Just came from Drift Works channel...now subscribed👍😎😁
Just found you - thanks to Mike at Rennch.
Loving this first up - now to watch them all.........lol
Enjoy!
I look forward to the suspension video because you did tell us that you have something extremely special up your sleeves
How does this channel only have 6k subscribers?! I just binge watched all the videos in a couple of days. Amazing series and I’m looking forward to the rest of it. Hit subscribe guys! As a 964 owner, I’m amazed, intimidated and inspired by the work being done here. Your ingenuity is something else!
That is a very nice comment. Thank you very much!
Great work, as always. Love the build!!
Great looking exhaust. I would have added the TT pre mufflers (since you already bought them), or 100/200 cell sports cats.
Great videos, since I found your channel I always look forward to a new one! Can't wait to see more of the engine build!
Love it... Nuclear option become a politician and change the law!🤣😂
That's a nice looking exhaust system. Looking forward to hearing it.
Me to!
Stunning!
Looks great! Can't wait to hear it.
Me too Todd!
Very nice. Quality as always
Perkele snyggt!! I really enjoy your vids Jonas! Please keep making them! Hat comes off 🙏
Jag kunde inte sagt det bättre själv. Grymt nöjd!
Can't wait to hear it
Sweet ! As always !
Keep up the good work! Let's hope that the parts you are waiting for will arrive soon, so we don't need to wait that long for the next episode.
I hope time and part allows me to get the next one out shortly 👍🏻😄
Really enjoy your channel. You are a born educator. Keep up the great work.
That’s very kind words. Thank you!
Loving this build your doing. 😊
So wish I could afford a 964 here in Oz to play with. So many modern improvements to be made and modern engine management may not increase BHP all that much but boy should it make it drive nicer 😊
Amazing!
cant wait to hear this set up, i have the GT3 set up with Rothsport headers but there is a drone that can get irritating on drives.
Straight out of Sweden
Indeed, but with British exhaust!
Another great video, loving your work! Looking forward to seeing the suspension video already, my guess is a Tractive system?!
Thanks! It will be something new ;-)
Love your channel
Me to ;-)
Super knowledge 👌
Cool! I guess the GT3 aside from sound restriction look also quite better. I know its not its purpose but still. Also you save way more over stock 964 if you count the second muffler, original must be about 40kgs at least! Crazy.
I do really like the one I ended up with and everything has is charm of course. Original exhaust is a beast!
Great build videos. Have you been able to start up the engine with the TT exhaust and get dB measurements?
Not yet…
I think you should put catalytic converters in it. Even racecars should have it and it will help you get the exhaust quieter.
I might end up doing that in the end.
I would add the little silences straight away, you are on the limit anyway, a quieter car is always better to drive (less driver fatigue) and getting kicked off a track is a huge waste of time and money. 👍
Good work as usual.
Regardless of which I will make sure it's fabricated so I can switch at the dyne run! I have all the bends and everything already.
@@islandworks Ska du regga denna för vägen också, så är det väl 84 dBA som gäller
@@tommyymmottommy jag tänker att det brukar vara mer flexibelt på det.
@@islandworks ska du regga som ombyggt fordon genom SFRO/testa? Jag ska göra bullerprov i veckan och det finns tyvärr ingen flexibilitet 🙂
Du får köra med reg/bes-system och sedan kanske du råkar tappa en dämpare eller två 😬
@@tommyymmottommy SFRO som ombyggt fordon är det tänkt. Då blir det bananer i slutdämparen…
TIG is not an easy skill, I'm teaching myself aluminum now then on to stainless. Keep it up!
It’s tough man! But I’ll get there eventually!
The key is cleanliness. Everything must be sterile inside and out. It’s a good idea to backpurge with stainless tubing to avoid sugaring. I still have a lot to learn, but I managed to weld for Singer for a while. An amazing opportunity and something I’m very proud of. Tig welding is a worthwhile skill to learn regardless of the steep learning curve.
@@Russell_and_Rosko that can not be underestimated as it seems. One step at the time and I’ll pick it up eventually.
Great exhaust set up! Are you eventually considering turbo-ing your car?
This car will unlikely go turbo
Came over on Phil's shout out. Does the system not need a Flexi, or some kinda slip joint? I get that it's mounted to the cradle of the engine so you don't have the usual engine to chassis movement, but thermal expansion?
There is some flexibility in the collectors as well as the mount to the engine mount is flexible (wide piece of sheet metal).
Have a you thought about using twin supertrap muffler tips. You can tune the sound and performances.
I used to have a supertrapp on my super motard bike many years ago. They are nice!
@@islandworks there is also something called a "beehive muffler ". They slip into your exhaust tips. Not tunable, but do reduce db's with out restrictions. I have used them on motorcycles with success.
I think flipping the backbox 180 and having the tips come out of the number/registration plate recess would look cool! Literally 0 advantage tho 😂 unless you wanted to split hairs with shorter runner to the backbox etc
That could be an interesting setup! But where do I know put the tag-plate?
@@islandworks ahhh didnt think you was running them being a track car, well theres that idea then 😅 also just an idea, if its a flying db reading and not a static they do, you could cut some pie cuts and have the tip s face down, helped alot with my r34
Nice. But why don’t u use V band clamps? I’m just curious
Terrific video thank you
I wish I did actually. Maybe I can fit it now?
@@islandworks it just makes it so easy to remove pipes. I like watching your videos. Thank you!!
how do you know if the tips will be in the middle of the body of the car?
I just measured side to side so that it sits in the middle of the engine. That’s also the middle of the car.
Looks really nice 👍
A bit surprised that theres so short secondaries. Ive gotten the impression that secondaries are equally important for the scavenge.
But I can see how theres a problem fitting longer exhaust 😅
Atleast you now get longer secondaries than with the gt3 muffler.
It’s not a lot of space in there 😅. I have a feeling this will work well though.
great, if you ever need an assistance :D greetings from germany
håller du till på öckerö?
Ja
Great! nice work, well done.... at the end the last weight saving is going to come from you! need to workout and loose some pounds!...🤣😂
Indeed! That’s a much more complicated project though 😂
@@islandworks that’s right! Love your work.
I know 95 dB seems low but my local track (in France) has a limit at 90 dB...
103dB at NCM - which is also considered low
I can offer to speak to the local politicians if you think it helps :-)
@@islandworks In swedish? I'm sure it would do lots of good
A for effort? 😎😎
@@islandworks You mean Å for effort!
I'm gonna go with none of that setup meeting 95dbA... 😬
My career as a politician is about to start…
@@islandworks yup!
@@msitpro1 I’m quite confident it will get bellow 95 considering I was bellow before with my previous setup. Let’s see!
Please become politician in Denmark instead, Sweden is way better off in regards to modifying cars than here in boring Denmark 😂
