SOUND UP! Ultimate Porsche 996 aftermarket exhaust group test comparison!

Big thanks again to BOTB for sponsoring this video, as well as Porsche Centre Portsmouth for hosting the group test. My biggest thanks though goes out to the stellar chaps who brought their 996s along for the day and took part in this mammoth 996 group test!

It's the Porsche 996 group test we've all been waiting for! Which is the best route to go down for an aftermarket exhaust system on the 996 Carrera? To find out, I assembled a big group of Porsche 996 Carreras from both the Gen1 and Gen2 eras, each with different aftermarket exhaust systems fitted to their cars. Here, we conduct a sound-off of each system, with static revs and drive-by clips, as well as decibel readings.

Which is the best sounding aftermarket exhaust solution for the Porsche 996? Let us know in the comments below!

The red C4 at the end sounded the best.

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 YouTube 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.

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

[donaldgourley]

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

[Revival]

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!

[zangadozangado]

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

[skydivers]

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.)!

[sgttombailes]

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.

[Nord_Mann]

Fisker Gundo (last clip) takes my vote👍🏻

[joelsmith]

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

[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.

[michaeldrew]

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

[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

[alexrankin]

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

[MikeTerry]

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

[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?

[tonyharper]

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

[bruskibeat]

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
