On most cars, a catback exhaust will typically only change the sound and HP change will be modest at best. Glad you showed that whopping 2.5HP gain. The only car I ever noticed a difference on an exhaust mod was an '83 Mustang GT. It had restrictive iron manifolds with very restrictive emission gestapo butterfly valves that then went into a single tailpipe. I put in full length headers and dual pipes and wow - like a different car. The seat of the pants difference was huge. Nowadays, exhaust efficiency is pretty much maxed from the factory.

We need more videos like this on youtube, very well done mate, I've been viewing your videos for about 3 years now and I am thankful that people like you exist on this planet, where you take the time and put in the effort to teach us, what is good and what is not, how things work and what you can do to your car to increase performance.

Although this exhaust is freaking expensive, and provides little gains(some but little), I think just having a titanium exhaust is cool enough.

iLupi Exactly. It would be foolishly short sighted to only chase hp gains with no regard for weight. The combination of small hp gain and significant weight loss yielded really good results overall, while still keeping the car very comfortable to drive on the street (i.e. no headache inducing droning on long highway drives). This is physically an excellent upgrade in every objective way and the only downside is monetary cost. When titanium production and fabrication advance and become more cost efficient, steel exhaust systems would be rendered obsolete.

Power is good for acceleration, but weight reduction improves acceleration, braking, and cornering! 👍 Also, the S2000's engine is close to it's maximum output in stock tune, and the factory exhaust is as well. Amuse knows this and took the factory exhaust and made a meaningful improvement to its design. Japanese mindset.

smokenrowboy probably not any benefit to cornering because the weight removed was very low to the ground. If it was a non-convertible and he installed a carbon fiber roof, or if he installed a lightweight glass windshield, that would help with cornering.

I think this sort of says how efficient honda's stock design already was. i'm guessing regular economy cars may have more restrictive exhausts so it might be worth aftermarket exhausts, but honda knew exactly how much power it wanted to make, so they made the entire car as efficient as possible within the parameters they were given (material type, legal restriction, etc)

Tetsuto Kamata. Exactly. Most air filter housings and exhaust ( not exh manifolds) systems are probably 90% as good as they could be. Replacing them adds only a tiny bit of efficiency to the flow, especially at part throttle or 2/3 up the rev range. Full throttle is different, but how many times are you at full throttle above 5,000 RPM in any car. Some drivers, never, an enthusiast like me, maybe .1% of the time I'm driving.

Actually titanium is more responsive to the exhaust gas pulses, it works like a bell if you will. So it brings out more frequencies producing a rich, crisp and throaty sound! Performance-wise the pulse responsiveness helps the exhaust gasses to maintain optimal laminar flow and that teams up ideally with the straight through resonators!

Wow Jason! Indeed this was a great learning experience with all those realiable numbers! Thanks and keep it up!

Not so sure without seeing some comparisons with that specific engine. As I learned with my current car, some cars rely a bit too much on exhaust pressure to keep the engine able to drop power down at the snap of a finger. A car I owned in the past however nearly doubled in power by removing the cat entirely and using much larger pipe (it was bottle necked by exhaust pressure until I tried 3" pipe).

The information learned from this video is worth the money. Long term gratification will outweigh short term.

And, you actually improve braking and cornering too. How much would it cost to lose 35lb by either replacing a few body panels with carbon or quality lightweight wheels, bucket seats and so on... . It is for sure expensive, but imho worth it!

Victor Dominguez this is a beautiful piece but there are other titanium exhausts for the s2k that's about the same weight and costs a lot cheaper. I had my s2k with a Trust (now GReddy) TI exhaust, and it was 9 lbs due to the muffler being cylindrical instead of the shape of the Amuse ti exhaust. That exhaust costs $1k compared to $2500 but was better, imo, than the Amuse. Amuse is a great tuner from Japan, no doubt, and whole replacing panels with cf is great and saves a lot of weight, it's not something I'd consider as well, unless the car becomes a show piece or if I have money to burn just like that. But anyways, I'm not trying to go against you and I agree with you at some point that this does not sacrifice anything about the car, but there are other cheaper options out there for the s2k for far less money, too.

Thank you for the extremely detailed test and all your great videos! So few people actually account for temp/humidity/pressure and breakdown exactly where the changes are happening. Idea for a future video: Strip as much weight out as you can (spare tire, everything in truck, possibly the passenger seat, etc) and use the Vbox to show how much faster. Or kinda do the reverse and add a bunch of weight and remove it in measured amounts between tests, and change the weight location (trunk vs passenger seat) to see if it makes a difference (maybe weight over the rear tires would help traction for launching)

Love your Honda, thank you for the informative video, many upgrades in the market seem pointless, but the weight saving was impressive!

Very well done video. I really appreciate your approach to testing. I did quite a bit of modding to an '01 B18C Integra i had a long time ago and i can say i spent a lot of money wringing very modest gains. It was a great car and i enjoyed it for a long time but as far as $/hp and tq... there would be far better cars to invest in. Great video... i look forward to watching more from your channel.

Everyone know a loud car= a fast car

Tell that to the riced Hondas that I toast in my Caravan.

The S2000 is one of few cars whose stock exhaust actually gives a similar amount of power to an after market exhaust, so on this car buying one would really give little to no gains. However on more restrictive exhausts it could really make an impact

I got an accord k24 with one and if it doesn’t make it faster it at least makes you feel like it does lol

Great video - love all the data points, comparisons, etc. I would say that over the years of modifying cars, I've re-done some mods because I didn't like the first (or sometimes second) mod. I remember one car that I owned I tried 4 different "catback "setups before I settled on one that I really, really liked. Exhaust systems, in particular, can really make or break the car. So, don't worry about the cost. If you got it "right" the first time, that's worth a lot...and it's hard to put a dollar amount on that!

Best video I've seen where the sound difference is noticeable! I've been debating stainless vs titanium for my new set-up and prior to this leaning towards stainless because I couldn't hear a noticeable difference, now I'm rethinking my entire life... haha

Using a web based calculator (and assuming your actual altitude is 4000ft), the Density Altitude of your stock test was 5130ft. For the catback test, it was 4074ft. Density altitude is a good way to compare results for tests in somewhat disparate conditions. Using the difference between those (1056ft), the power difference "should" be about 2.5%. Add that to the 1.2% lighter and 1.4% more powerful. Total of 5.1% gain in acceleration. Checks out :)

Very cool - actual altitude of the test is about 2700ish feet, probably no higher than 3,000. Does that calculator account for humidity?

Colder air holds less water than warmer air, so that explains the difference in humidity reading. The performance increase due to lower temp far outweighs the decrease due to higher humidity.

Do a video on the power gains of a cotton or foam air filter over paper or comparing all three

I’m surprised it didn’t get much louder! Great comparison, great in-depth review video!

This is a a rare video that makes me happy to be a car enthusiast. You are the stereotype I wouldn’t mind claiming as my own. Keep up the good work mate👍

You probably knew that it wasn't going to be a power difference. It is a great and worthwhile mod if you are looking to cut weight.

2.5 hp to the wheel is really no small thing. its way more significant than 10 horsepower motorwise. and your car is lighter now so thats great improvement

I usually don't follow ads but I've been looking for a Focus ST recently and its so hard to check every website and see what is being offered and where. Gonna give AutoTempest a shot

This is probably one of the best video on the internet comparing this type of modification

The S2K is probably the best sounding 4pot out there.

What's that weird T joint with the capped of pipe in the exhaust? Some kind of Helmholtz resonator?

As EE said, T joints and J-pipes are used to cancel out a certain frequency range to eliminate unwanted frequencies; destructive interference of sound waves.

Yes it is a Helmholtz resonator.

You're the man my friend. Good job! 👍

Such an honest video. Really cool man. Enjoying your videos more and more. And I think it goes to say that losing weight is quite impactful. Is there any video or explanation regarding “losing some pounds vs gaining equivalent HP”?
