Do Aftermarket Exhaust & Intakes add Horsepower?

The question that everybody wants to know is, does installing an aftermarket intake & exhaust add hp to your car? Today we have the Fitment Industry Boys over to test just this on their new Honda S2000 giveaway car. We do same-day comparisons on the Dyno to see if these parts truly add hp.
Check out this Honda S2000 on the Fitment Industies channel as well!

What's the first mod you would do to your Honda S2000? Let us know below!

[@hyper8545]

Forget about a tune and power. We all know the reason why we like these mods. The sounds 👌 🔥

[@HippieSkippy100]

Great seeing two of my favorite channels getting together. A great tuner and great wheel provider. Ya'll gotta do a collab build together with MAP parts and Fitment wheels etc.

[@Tonyyyy_666]

On Hondas bolt ons always make a huge difference

[@asmongoldsmouth9839]

A 5.7% gain. Not bad. Too bad that cost $1,000+ to accomplish. I'd rather spend another $1,000 and get a turbo kit first. Much larger jump in power and acceleration.

[@K03sport]

...not sure how much power; but how much weight can you lose (from the car)?

[@yubentrolled7097]

The only thing in my opinion the S2k needed was monoblock calipers.
Back when Honda made decent cars. My my my how times have changed.

[@Rhosticks]

Nice!

[@nwbklr]

18% power loss from the crank to the wheels. This car needed a tuneup before anything else was done. That is NOT a good baseline.

[@pault6533]

I like my titanium exhaust, subtracts 30 pounds in addition to the hp and audible improvements. Fun review, thanks for doing this!

[@darksideracerx1]

Those valve seals are showing age or the pcv needs changed.

[@blknblubkrdude]

Probably rings like mine is, not worth worrying about

[@adanmendoza7517]

In a NA s2k all you need is Single 3inch exhaust, 4.56 gears and tune. Intakes are irrelevant in s2ks

[@princealideababwa1485]

Can you tune the car for more power after doing something like that?

[@KaedeHot]

With manual tuning you can gain more power yes.

[@okevolutionviii]

Before I watch the video, for over 20yrs, S2000s are notorious for not making peak gains with aftermarket intakes and exhaust while costing hundreds of dollars($100-400) per HP where they do make gains.

[@maperformance]

Well, after the video what do you think?!

[@jjoergensen]

If you clearede the lem filter, well you could get more HP, its a Great intakte setup.
And the muffler deleted, well I also thought if would give more, so kind of …not a Great idea.
Some cars are just already tuned

[@fegbsc9564]

Catless exhaust add more horsepower...

[@maperformance]

More horsepower, but not emissions compliant!

[@brendanloriogara2071]

PPE

[@nwbklr]

Kinda useless without seeing the overlapping power curves so we can see gains throughout. 🤷‍♂️

[@Locallybuiltauto]

First

[@nwbklr]

This is so ridiculous, “ITS INSANE….ITS. CRAZY THE GAINS!”
These fools are acting. Straight up. It’s EIGHT hp bruh. That’s pathetic.
