Very useful. This post should be pinned.

[@Steve_MFr]

Thanks Chris. I was just thinking: it's a shame Lee didn't post the db numbers and time stamps😝

[@---rg1gb]

For the win

[@BoneyBobsTreasure]

Ive had my 996 3.4 for perhaps 10 years having started on classic Porsche 30 years ago, and finally got tired of 'classic car' problems and bought a water-cooled car. I have done plenty with my 3.4 M030, 3 spoke wheel, interior improvement, years of work at Hartech etc that experience lets me say your tests and videos are the best on KZbin for this whole model series. Thanks for that. When I am about to spend perhaps £1000 I want a decent review and when I look for useful content it is almost always you who provides it. Its a bit annoying as TBH I dont actually like the channel name and occasionally I dont like some approaches but they're both because I am 50+ and we still have much more in common than in difference and youre still, compared to others, clearly the best.

[@ElijahNicolas]

I’m surprised no one had the PSE option. Cheers to another great video!

[@tayne5009]

The red C4 at the end sounded the best.

[@mikekcarey]

Agree I think the 3.4 has a great sound above 4000rpm a real hi pitch wail. 👌

[@727skydivers]

I had to go all the way with my 996 3.4L (corrosion. many miles. winter. Scandinavia. salt!); Cargraphic full exhaust system (with 2x100 cell cats). Sounds amazing! A lot more expensive than the partial replacements tested. Still happy with the upgrade (4600EUR + VAT). The best sounding 3.4L 996 (what else could I say? I paid my hard-earned money for it.)!

[@sgttombailes3380]

I did a double gundo hack to my 996.1. 1/2" middle cross over pipe w/ 2" overhead pipe. Sounds AWESOME! Neighborhood friendly until you give it the GAS!!! Sounds like it's on the track.

[@Exit.The.System.]

Hey 👋🏼 is the main bypass 2” , and where did you do the 1/2” ??? Thanks for putting in sizes , no one ever does with gundo , so never know if it’s 1.5 or 2”

[@Nord_Mann]

Fisker Gundo (last clip) takes my vote👍🏻

[@computerhelpcc]

Having had Fister on mine for years now, would never have a 911 that cannot match it, and many don’t. Good enough that I don’t envy V8, V10, V 12. 3k to 5k is so good that daily city trips are supremely satisfying.

[@996Revival]

I had a hard time picking but I think I like the Gundo hack and the Dansk the most but the black C4S sounded really good on the fly by😃

[@JAYREAD]

That’s a great video, Lee! Actually, I’m working on a similar video over here in the US and not one of the exhausts you feature will be on mine so it will extend the good work that you’ve done here. Great minds think alike! Top content as ever!

[@HLinHD]

Interested in this!

[@JAYREAD]

@@HLinHD stay tuned!

[@donaldgourley3716]

Lots of videos on KZbin for any topic….yours are the best. The Go-To channel.

[@AlexanderTheGroupGT1Racer7]

That car is considered as a supercar!

[@zangado1zangado188]

I was really hoping there would be a Kline system featured. I have researched every You Tube 996 Exhaust video and by far think Kline has the best sound….Great video though it is much needed for the 996 enthusiasts

[@Henders72]

A friend of mine has a Kline on his C4s, it sounds absolutely awesome., unfortunately for me it was more than I wanted to spend when I replaced my exhaust. I went for a full top gear system with 200 cell cats and mild back boxes. A vast improvement over the standard exhaust, a little droning at low rpm’s but sounds great on full chat, if I was replacing again I would look at the miltek back boxes, if money didn’t come into it I’d go Kline or cargraphic, as most of theses things it’s all subjective for personal taste.

[@michaeldrew64]

Agreed ... PSE system is missing ... have it on my Gen 2 and love it ... Very enjoyable vid though.

[@steveashborn4872]

I have had the Top Gear set up but am getting a warning light and cat bank error reading. Any ideas? The website states no ECU remap needed??

[@day_of_the_jackal]

I’ve got topgear 63mm 200 cell x-pipe with their loud boxes. The x-pipe completely changes the sound. Makes it roar at low revs and screams like a gt3 at high revs. It does drone between 1.8k and 2.8k.

[@MikeTerry94]

I’ve got a Spyder performance on my C4S - love it, the sound is addictive in the higher rev range

[@JohnBaxendale]

Curious how it's lasted, 3 years on, they only give 1 year warranty which doesn't sound too much :\

[@joelsmith9311]

Thanks for the video, I'm literally pondering which sports exhaust to put on my 996 at the moment - so this was perfect timing!

[@benterry2681]

Everyone has said it but wish we had a standard PSE for comparison. I’ve got a PSE but would be nice to know what’s on the aftermarket for when it needs replacing

[@ism671]

Spyder performance valvetronic

[@alexrankin2235]

I absolutely loved the red car at the end. All the exhausts sounded great 👍

[@tonyharper5604]

I have Topgear manifolds and Milltek Cup exhaust. Doesn’t drone and very low down sounds fairly similar to PSE but once you hit about 3k revs, it is pretty loud. At its loudest between 3k and 4.5k I would say and does rob you of a bit of induction noise through that section of the Rev band, but I am pretty happy with it

[@marcusoutdoors4999]

Very useful and interesting. I was particularly put off from going down the CSR route.

[@thecasualpetrolhead]

Very cool group test of aftermarket exhausts. I think would have been nice to compare these to the PSE as well, just as reference. Great content as always! Keep’em coming

[@4130burton]

Great vid and comparison Lee 😎🤜🏼 Shame nobody had aftermarket manifolds/headers fitted. Mine has aftermarket headers, Eurocupgt 200cell Cats and Milltek Cup Silencers and sounds completely different. Favourite sound I think, must be Justin's, with the Milltek 😉👌🏼 Well done to all and they all sound awesome to be fair! DANSK get your act together and sort out the quality and flexis - I want another set! 😂

[@sibbese3740]

Very good video. I think Gundo hack sounds really good. A big part of the engine sound also comes from the intake and it would be great to see a propper carbon intake mod compare on the 996 too.

[@bruskibeat9164]

Great video throughly enjoyed it ,I own a gen1 996 on standard exhaust..looking to replace and this is the first time someone has done a review like this with a full spread of exhaust types great idea and now I’ve decided I’m going with the top gear with the 200 cell cats..keep up the good work 10/10

[@rousemotorsport]

What do you think of the Muffler bypass option? Much louder, HP boost, and less weight.

[@pegcity4eva]

It's insanely loud so if that's your thing.

[@BUBBAGOLF-996]

I was looking to upgrade my 99 911 996 exhaust, did a gundo hack already, i was looking to upgrade n get the best sound, n not to loud n wake up the neighbors:) and I ran into your vid❤ really nice get me some idea - I’m looking at cargraphic mufflers n headers- let me know what u think, I will spend that much; I want something that worth the $, thank you much - Bubba

[@julian987r4]

I think the Miltek is the one for me, however something tells me the original PSE would be the best. So subjective though isn’t it, they all have their merits. Great video!

[@stewartclough4866]

That's what I have no droning if you are under 4k. Turns heads when you wind it up😊

[@philnelson2607]

Great to see you at Fried Eggs 4 yesterday Lee 😊 really interesting comparison here but the fister/gundo fir me still sounds the best. I have the Porsche PSE on my .1 and get nice complements all the time on the sound and no drone. But, an expensive retrofit. Soo I guess fit total value for money the gundo/fister has to be one of the best options I recon 👍🏼😊

[@yongkim777]

I wish you would have had a Fab Speed & Soul and a BBE exhaust system included also🤔 Good comparison test! Thank you!

[@Krnnerdboy]

I have a 996 with vision motorsports 4.0. Running fabspeed x pipe, headers and borla corsa mufflers. Sounds really good on the low end but it sounds really boring and raspy after 4k rpm. I think stock mufflers and gundo might do the trick for me

[@JamesThomas-wf9sl]

Brilliant video Lee, I can't think of any other video that demonstrates this as well as you have, utterly out of the top drawer. I have a 996 C4S which is running a non-switchable 997 set up, but in essence its still pretty stock. I thought the Milltek and Top Gear set ups sounded the best, all the other setups were also good, I was surprised at how good the Gundo hacks sounded though, bit less noisy on the move but really good tone. I'm thinking I may Gundo hack my current set up first, then if that's not what I want look at a cats and system upgrade. Need to do the suspension first though!

[@Gertzerroz]

Could you do a video like this for 997 exhausts?

[@johnfj80]

Great video, the sounds are great ,I love my 996.1

[@aggie3344]

Hayward & Scott in Basildon have done the exhaust bypass on a couple of my Porsches it’s the closest your going to get to a factory PSE

[@JakeKitchener]

Awesome comparison! I've done the gundo on my 997.1 and it's by far the best sounding car I have ever driven!

[@ezgtte]

what the arrow in the app in pointing at ?

[@NorwegianCarGuy]

Cargraphic wins it for me, perfect blend! Great video!

[@The_Schimpanski]

The 997 GT3 is the best sounding watercooled Porsche ever. I always wondered if it is possible to replicate that sound on a 996. Has it ever been done?

[@damienisabella2059]

PSE vs gundo hack? Any thoughts?

[@khestehave]

Yes!!! A Dansk Sport with the Gundo hack!! I’ve been looking for someone who had that done!! Looking to do that on the C4S X51 because as you have reported….the Dansk Sports aren’t really great sounding. Superb video again Lee!

[@wesmason9914]

Terrific video. Especially liked the variety and the way each car/mod was examined, as well as the customer testimony. Very surprised that that wasn’t a Fabspeed solution in the mix. Maybe it’s too much $$$. I know Jay Read did an exhaust video here in the US which was really good. Like this format better personally. Hope to see more content in this format on future mods for 996’s. Cheers!!

[@9WERKSTV]

Glad you enjoyed it!

[@Dimpala]

Muffler delete is best sounding😎

[@SF_Native]

I liked the silver one with Cargraphic exhaust + Gundo hack. I would have like to throw my 996 into the mix with FVD exhaust.

[@alexkosarek9931]

This is one of the best videos I’ve ever seen

[@lukeskywalker1574]

Car at 16:25 sounds best to my ears!

[@allenh7266]

Good comparison, well done!!🥰👏👏👏

[@faresbenghali1908]

Cargraphic Sport Silencers with Gundo Hack - 106DB IS THE BEST ONE 🥶

[@arvidkarlberg5845]

have a 1999 with x51 so different intake and headers but just with gundo it's perfect for me

[@saquibramday]

Great content well done Lee

[@dwarfyh32]

Great video. The Milltek was probably the best for me

[@9WERKSTV]

Thanks!

[@stu1923]

Thanks Lee! Been thinking of changing out exhaust & this helped greatly. I’ve been leaning towards the Fister mod (type of Gundo hack but before the silencer tube mod. I still think it has the most crisp & tight sound of all and will be going that direction. Cheers Stu

[@carreralicious]

Last one was the best sounding.

[@modernworldiscrap]

the 996.1 GT3 stock exhaust still the best

[@richardfitzmaurice6508]

Gundo hack with manifold for GT3 sound

[@Apexjuha]

Thanks

[@motorsandmeats88]

Hi Lee. On the standard-with-gundo, do you know what pipe diameter was used? Great comparison!

[@eujeniu8527]

Very cool video, thanks, Lee!

[@go4384]

The Top Gear (open) or Dansk with Gundo were tops.

[@TheRacerRich]

There should be a version with all the clips one after the other with the name of the exhaust below.

[@12345rpm]

Agree!

[@Greg-xk7sw]

Dansk super sound silencers for me. So long as it’s not droney on freeway.

[@dazsolimani2437]

Another good and informative video 👍

[@9WERKSTV]

Thanks Daz.

[@Inazuma68]

I am pretty happy with my GT3‘s standard exhaust 😎

[@kimthomas3005]

No "cup" silencer delete i notice

[@garyhaddock7264]

Excellent video, lots of choice!

[@9WERKSTV]

Cheers Gary.

[@wezzla]

Wife: What are you writing? Me: I'm commenting on a 17 min video with only exhaust noises. Wife:

[@9WERKSTV]

Ahahahaha!!!

[@HawkMillFarm]

Having the standard PSE for comparison would have been good, also a big bucks aftermarket one, those were mostly cheaper than I though you'd need to spend. I couldn't come to a conclusion to which I liked best but the std C4S always seemed nice to me. How about the same for 997 and 991 .1 or .2?

[@nigel.w]

My vote goes to the Top Gear setup. Best drive-by sound, IMO.

[@esteemedenergy]

My biggest issue with 911’s, the sound, and none of these really give me a chubby.

[@sidewayssam]

I had a dual bypass Dansk on my series 1 , controllable on a fob. I will post a link

[@nzrobinz]

Not a fan of any of them really the standard sound gives enough noise for me - but I have a Carrera3.0 and that is loud my 928 is also not too loud but a great v8 sound so nice to have a quiet Porsche

[@computerhelpcc]

928S had perfect sound. 996.1 with Fister’s Gundo hack is PSE in permanent mode and its fab. Still, can’t beat a V8 from idle to 2,500 rpm

[@jazzdrumguy5044]

My favorite was the Spider Valvetronic. On my 2000 996, I have the Mille Miglia exhaust out of Australia, which is killer. It has a nice rumble on cold start, with some pops, and under 3K rpm, it's not too obnoxious. But over 3K, and in the 4-5K range, in 2nd and 3rd gear, it is a monster! It's not like an Italian rumble, like a Borla, and actually sounds like an air cooled. When I downshift into 2nd, you can hear some popping too. Nothing outrageous like modern supercars, but definitely a rumble that can set off car alarms. And no drone! Here is a quick video of before (stock) and cold start with the MM's. kzbin.info/www/bejne/raeydp2Mg7xqd6M

[@pye007]

not impressed with any. Suggest try the TechArt unit. Much better

[@henryatkinson1479]

Still prefer stock or PSE.

[@ejtisevn]

996 likes O_O

[@randominternetuser2888]

If you care how your high performance car sounds... you're doing it wrong. The only thing I want out of performance parts is... Performance I don't exclusively drive Porsches for the same reasons Harley riders choose their motorcycles.

[@christrees664]

Fuck me it's David Beckhams voice box

[@2702simmo]

None of them sound particularly great and I say that as a 996 owner. The noise at full chat on these sound a bit fast Ford I think not a pleasant sound. I wish mine was a bit quieter

[@roywein1880]

Agree. I’m a 996 (C4 ‘99) and none of these agreed w me. Especially w no HP Or performance add. Not a worthwhile add imho

[@adamsangels9874]

Jesus just get a v8 and be done with it

[@PrimeMatt]

Far too much waffle 👎🏼

[@BastardLikeAFox]

Great video, thanks!
