Default How loud is your car in cruise?

So daily driving this S2000 has become a headache.

It has a full 3" exhaust off the turbo (wg plumbed into exhaust) with two rear mufflers and no resonator. I never had any complaints with my turbo 1.9L with its 3" exhaust to magnaflow straight thru muffler, it was actually really quiet. But mothe r f ucker is this Honda ever loud!

Although its not the most accurate thing in the world Im getting approx 92dB on my dB meter app, vs my stock civic si which reads about 75dB @ 100km/h

Anyone ever measure how loud it is inside there car in cruise? (windows/top up obviously)


Time for electric exhaust cutouts and different mufflers maybe?



I would do this but I don't want the cutouts to flow thru the resonators aswell, kinda defeats the pupose of cutouts if they are being restricted.

Then again I guess this car is still quiter than the FE3 in my Miata lol

So how many people here roll with earplugs? Or do you have your exhaust system are plugged up with cats and resonators?

mine is completely liveable (no drone, no loudness unless on pedal); wife approved. IIRC savington measured his (same muffler) at 82dB.

I see no benefit to those cutouts but for MORE NOISE.

You want less noise, get bigger mufflers.

Mine is pretty loud..but very deep. 3" no cat and one "resonator" in place of a muffler. Driving normally requires and elevated voice to carry on conversation, but when the WG opens, it's RACE CAR ON. The last auto-X I did I hit the dB meter with 91 at WOT....115dB if I backfired. I think since the exhaust was new that it has gotten louder and louder over the years. I'd be curious to know what it is now.

Strangely, Jenn's MSM with a 2.5" FM DP, a nd Enthuza 2.5" exhaust w/cat and resonator was louder than my car by a lot. The exhaust note was MUCH "sharper" than mine. In fact, it had just the right frequency that is caused a lot of vibrations through the exhaust adn now I can't keep one of the manifold studs tight. I did put the stock muffler back on (still having the 2.5" dp and mid-pipe) and the car sounds nice and sporty now...ver quiet inside the car when driving and deep/mellow outside the car and it's clear the exhaust note is not stock. Perfect.

Too loud. I even wear ear plugs driving on the street and anymore than 20 minutes, my ears are ringing after.

I have one small round Magnaflow muffer (14" iirc), 3" exhaust. I can't hear my engine if I'm beside my friend's skyline though, so I don't feel too bad.

I think last time I measured mine on the highway, it was about 85db at 75mph. This is from about face level in the driver's seat with a cheap SPL meter. The biggest problem I have is that it drones really bad at 1700rpm and about 3500rpm, and a little bit at one spot in between. I currently have a 3" enthuza with a cat and 18" magnaflow. I want an exhaust like Brain's, maybe even with an extra resonator somewhere just for extra quietness. If I could get it stock-quiet, I would be a happy camper.

Mine is nice and quiet, looks like Brain's with the huge 3" Magnaflow.



I'd vote to add a resonator, especially if you have a straight through test pipe on the car now. It'll be very easy to swap in, still straight through and will help to quiet it down a good bit.

Damn... I thought mine sucked at 86dB at a 75mph cruise with the hard top on and the windows up.


That's measured on the 'Sound Meter' app on my Samsung Galaxy S2.

What are you guys measuring on?

Brain, how is your muffler tucked up so nicely while all the NBs I've seen have a giant muffler dangling below the bumper? That has always bugged me about my exhaust.

Just loud enough so I can't hear all the sqeaks, rattles, vibrations and ---- being thrown up into the wheel wells. It's also too loud for my neighbours if it idles for more than 2 minutes.

I would swear Brainy has an NA, and not a NB.

Yes, I guess my question was more whether the difference is his exhaust, or the car.

Reading fail. His sig clearly states it's a 91.

My full 3" looks like this.





There is plenty of room for a bigger muffler without it hanging down below the bumper.
Mine is also very tolerable. Its louder then the stock exhaust by a good bit but I never have a problem with it and neither does my girlfriend.
