Porsche 911 996/ 997 Gundo exhaust hack | Vlogs
Автокөліктер мен көлік құралдары
My Porsche 911 996 has always sounded a bit tame. Sure, it's got a 3.4-litre naturally aspirated flat six but, the standard mufflers do a good job of muting the exhaust note. So I was planning on fitting an aftermarket back box, but then discovered there was a much cheaper way to achieve the same results. Known as the Gundo Hack, it consists of a welding a small bypass pipe between the inlet and outlet pipes of the standard mufflers. This allows some of the exhaust gasses to bypass the sound deadening muffler thereby changing the tone and volume of the car's exhaust note. The modification essentially mimics the official Porsche Sports Exhaust. However, there is no switchable valve so the exhaust is permanently in sports mode. In this video you can see the modification being carried out and, compare the sound of the car before and after the hack in a variety of conditions.
So turn up the volume and see just how wonderful my 911 now sounds.

WOW that actually sounds much much more agressive!

I was surprised, it really does sound better. It might get a little annoying off-throttle if cruising home late at night, but I think it's something most will put up with when saving so much money vs the sports exhaust option

Believe in JESUS today, confess and repent of your sins. No one goes to heaven for doing good but by believing in JESUS who died for our sins. For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.(John 3:16)🥳❤️😗
wow. what a surprising difference! Sounds so much better.

Lovely sound, Matt. Probably added 50 "psychological" hp at the wheels too ;)

Best exhaust difference video on KZread for sure! Nice mod
Love the mod and the video! Finally someone who gets how to make proper before/after-shots (various manoeuvres under the same conditions recorded from the same perspective). Congrats on your sweet-sounding car, Mat!
That change was extremly neccesary, well money spent
Sounds about 10 times better. Impressive stuff
200 quid for that??? Fully worth it!

Joseph R i would go to the pub with this man for that
4:11 Sounds absolutely amazing here!
Very nice work comparing the two sounds, one of the best videos on YT about this.
Paul is a genius and a nice guy, always handy to know guys like Paul, really knows his stuff
Wow, what a brilliant sound upgrade! Brings that snarly boxer six to the sweet music it's supposed to make.
Sounds absolutely amazing, well done! It really amplifies the flat-6 sound.
Wow, I'm so surprised by the improved tone. I'm studying at a university but as soon as I graduate I'm buying myself a 996 911(I'm trying to save as I go) as a graduation gift. I'm so going to have this done. I even know a metal fabricator, so thanks for the tip.
holy moly what a difference in sound that is and such an easy and cheap fix. the neighbors must love you now 😂
Thanks for so many different angles for the sound difference. Not just one clip but many of them from various "angles".
The difference is incredible!! It sounds so much better now!
I recently purchased a 2002 C2 and showed this video to my mechanics. They were skeptical about the mod and did the hack anyhow. It sounds amazing! They were blown away by it. They said they would be offering this to their customers going forward. Well worth the money.
Very nice job of presenting the before and after aspect of the change!
Love the new sound. Worth every penny Mat. Great video, thanks.
Wow. That really is a great mod. The exhaust note is markedly more pleasing.
Wow, massive difference. Sounds brilliant
Best sound comparison I've heard. Definitely sounds better with it done.
this video is exellent! So nice camera angles and sound recordings :D
Sounds so much better now! And I can't help but wonder why the sound of an engine gets to me so much! (And a lot of other people!)
I come back to listen to this sound, it sounds to magnificent!
Sounds great before, but WAY better afterwards! Congrats!
Sounds great and thank you for the different comparisons between the 2 setups, I'm in a similar position as what to do with my 996.
Quality video, love how you had different conditions and angles
WOW! That's really an excellent hack! I love the new sound.
Love your videos about your 996 !
Love this video Matt. Keep the 996 videos coming. Love them!! 😀 have an 03 996 targa myself. Congrats.
that guy is a genius, it actually does make a big difference!
Amazing! Such a great car, in a beautiful spec as well! My dream car is a 997.2 2S, but I love 996 as well, especially this one!
Gundo here - so glad to see my hack on your side of the pond! Enjoy
It didn't sound bad before, but I really like the end result. Nice work! Shame there's no room for a valve because I can see that getting annoying on long motorway trips.
O yes now sounds like a proper sport car.
Paul did my car as well BMW M3. Fantastic bloke! Fantastic Job! Highly recommended
I have a similar mod on my 997 Carrera 2, and the sound is amazing! Every cold start is as much joy as the ride it self.
I can't believe such a small cheap mod could make such a massive difference to the sound! It sounds like a different car!
sounds awesome mat,well worth doing,sounds more throaty now all you want now is the matt Monro soundtrack playing in the car on days like these.
Can only use one word, Mat: EPIC.
Sounds so much better and not too crazy loud
Nice one! Loving these Vlogs!
Loving this series Matt!
wow.. that is the perfect sound for a 911.. love it.
Wow, Mat! This new mod/sound is so much better, than the old one. Well done, have fun! ;-)
Very cool man! awesome video, very satisfying to watch.
now that's a full test. thanks matey for sharing
Great idea, and so inexpensive! I have seen the E90 V8 M3 mod where the perforated tubes inside the standard muffler are changed for solid tubes. Looks standard from the outside but what a difference in sound .
Sounds like an old school Porsche. Nice!!!
These vlogs are great!
I'm loving this series!
What a beautiful car you got there. This got me thinking about adding a small diameter pipe to bypass my 350z, thanks for the tip! ;)
Huge difference. Sounds great
Awesome Matt, and nice demos
Very thorough comparison, and a lot nicer of an exhaust
Had a 'Gundo' mod on my 996.2, Sounded great. Paul is coming to do my 997.2 in February. Cant wait.
The 4k footage is amazing.
Paul the welder is a top bloke. His modded both of my e92 M3. The sound is incredible with the oem mod on the V8
That's a maaaaad difference. Awesome job.
Aw what a difference, you must be well chuffed for £200! Glad you got the roof sorted as well
OOOOOOOOMG I want one!!!
Fantastic mod! The UK exhaust mod is a popular choice for S2000 owners as well.
Damn, that exhaust mod sounds way better. That guy knows what he is doing. Bang for your buck, that's a good mod.
That's brilliant! Made it sound alot better!
That sounds lovely.
Fantastic, to be honest before it sounds more like just an extension of the engine noise but with the mod it has a proper exhaust noise too!
Sounds bloody awesome
Sounds alot better. Very informative video
wow, thats an amazing hack. That car is sounding far far better then before!!!! It gets my Double thumbs up.
wow that awesome .... thanks for sharing matt
Big improvement for not a lot of money. Nice job.
big difference! sounds very good now
Gotta love a good old NA flat 6, sounds pretty awesome after the mod !
This is probably the only 'hack' ever that is actually sick
Great job Matt!! thank you for sharing :D
That mod makes the car sound so much sweeter.
Whoa Mat surely has changed a lot in 5 years!
my seams were on there way out so ended up going the dansk supersound route (have a couple of before and after vids matt if you wanted to compair) but gotta admit the hack sounds very similar so nice mod matt ;-)
Love the mod and your channel. Seriously thinking of getting a 996 C2 cabriolet. But prices here in Singapore are easily 3x of that in UK.
That sounds great!
That's the best exhaust mod I've seen

Fantastic difference!
Now that is a worthwhile £200 hack.... Good find!
Wow, sounds much much better!!
Matt, I really like the colour combination of your 996.
The difference is night and day!!! Wow!!
Good thorough video with all that `before` and `after`... Think I would like it to be switchable.
Lovely Mat!
