Hum around 3k??
 

Hey guys new to the flat 4 world, here's my story, I just picked up a 2014 FRS monagram edition 30k on the clock. So I've had her for about 3 weeks now. It's lowered on bc coils, running 18" with 265s front and rear, "fat bitches" so I've noticed while driving in 3rd and 4th, around 3k rpm there's a hum not at 2900 or 3100 but right there at 3, I've got stock exhaust and intake, I'm just wondering if it's a normal thing with the flat 4 or if it's maybe something else. I know very little about this car, but from what I can tell it has been taken very well of. Any insight would be appreciated. Thanks.

Where-ish in Washington do you live? I ask because there's a shit ton of us owners up here. I suggest meeting up with someone to compare notes.

Welcome to the forum, ThisGuyTaylor ......... :clap:

No, it's not normal ...... leastwise not with my all stock (cept for the muffler) 2013 FR-S.

Those are pretty big tires for that car ...... could it be the tires making the hmmmm .. ?? I suggest you try upping the tire pressure a couple of pounds to see if it goes away. Maybe rotating them to see if that helps.

Do I read that right that the exhaust is all stock .. ?? That would be unusual for a pre-owned FR-S. You might check and make sure all the exhaust connections/hangars are secure.

Not everyone wants to sound like a high school kid with a 20 year old Civic, or deal with the attention that brings.. ;)

But I enjoy the noise. It doesn't have to sound like a 20 year old Civic just because it is louder than stock. There are many loud(er) exhausts for cars that do not sound obnoxious.

But, but, but, what if you have a small penis? How will people tell you have a flashy car if it doesn't make a lot of noise and detract from your undeveloped reproductive glands!

If you get it at 3k in neutral and not moving, that would be something vibrating that shouldn't, or at least could be tightened up or shimmed somehow.


Or humfrz is catching some Zs in the back seat.

I simply haven't yet heard an aftermarket cat/axle back for these cars that doesn't sound ricey, for lack of a better word. The closest I've heard to what I'd actually consider driving would be the Greddy Supreme SP...if there another muffler option that is quieter than that (other than OEM), I might consider it..

I'd buy a Harley in that case.

The TRD has a nice deep tone and although louder than stock there is not a hint of rice to it. There are several that give the same effect.

You've had it for three weeks. It's not a ship, and it doesn't have a vagina.

Just to clarify, it happens at 3000 RPM in all gears? Or just cruising in 6th?

It's hard to tell where sounds are coming from in this car, but can you get a sense of the direction from which it originates (front, back, underneath you, etc.)?

Corsa. They come to us from making Corvette and SRT exhausts and diesel mufflers. Nothing at all ricey about the sound.

Might give the wrong impression.

Would you harley have the cute little leather tassels on the saddle bag or not?

Not sure if I'd be man enough to ride around with purses strapped to the sides of my bike, just so I can ride from one bar to the next. It'd definitely have to have tassels on the handlebars though...lol. And I'd have to wear fingerless gloves and a Village People vest.

You have to buy a flashy colour as well as being noisy though. Just the noise does not compensate enough.

Do you think Magnaflow is one of them? And, do you think it will be same sound with a boosted (otherwise stock) engine?

As much as I want to have a light, rustproof catback, I just don't want to spend >$1000 for a catback and also face a surprisingly loud catback after installation.

Slightly off topic, but the borla axel back I think sounds/looks pretty good.
very similar to stock but slightly deeper, and chrome tips.

I also get a different sound which I can most closely describe as "hum" around 3K rpm with my AT/boosted engine. I think it is normal and due to design. It mostly happens when I want to accelerate without downshifting. I think you just need to downshift one more gear to accelerate.

I have never heard one in real life so can't express an opinion. I will not use sound clips to judge exhaust notes since they can be dramatically different in real life.

Like hot lava?

:scared0016:

Especially hot lava!

This ^ but with the addition that it can happen when moving as well. The exhaust resonates at different frequencies throughout the power band. Something that may not be an issue at all RPMs can become a pain at others. Odds are the problem is something loose or touching that resonates at 3000.

OP, we're just having fun while waiting to hear back from you. My question about your location was serious. Lots of friendly folks here in the upper left corner. Second best would be to post a clip on youtube and give us the link.

Why the knit-pick on gender classification on a non-biological subject?

All I was trying to say is that it would be unusual for a pre-owned FR-S not to have some sort of exhaust modification.

Heck, even this ol boy has an aftermarket muffler.

Why?

Oh, I suppose it is a carry over from my teen age years ... the louder a car was ...... the faster it was ....... :happyanim:


:D

Oh, I've had my share of loud cars too. In fact I'd be hard pressed to think of a car I've had in the past that DIDN'T have an aftermarket exhaust on...however I've really enjoyed the lack of attention this stock exhaust provides me..there's a lot to be said for flying under the radar.. I had a Brabus for a while on my previous car (W203 Estate) and ended up going back to the OEM Eberspacher, because of drone, attention, and zero gain (horsepower-wise). Maybe I'm just getting old...dunno. The 2 or 3 horsepower I might get isn't worth the price in other areas any more..

I'm entitled to be irritated by inappropriate gender assignments. I get the same way about people giving their cars cutesy names. It's not a pet. It's not female. It's an it.

Don't let her hear you talk about her like that.

Ya she will start to hum and once a female starts to hum you are doomed.

My nameless axle back with 5" mufflers and 2.5" piping sounds to be a tad quieter than the Greddy Supreme SP.

DANG, extrashaky ...... is it a slow day up in your neck of the woods ..... :D

I'm pretending to work. Like Tcoat.

It helps to provide more specifics about the noise.

High frequency? Low?

Source of sound? Front? Transmission? Rear? Make sure it isn't from the thin, poorly installed plastic trim vibrating or rubbing together. This is the entire car, by the way.

Any vibration through the peddles? The steering wheel?

Does the car stop and start? Does it track straight? Is it happy at redline?

In my opinion, if a hum is your only concern, then you have the best car in the world. Every now and then a thread pops up asking 'is my car okay cuz it does x, y, and z.' The answer is invariably yes. Just be grateful that this is your only concern as it pertains to noises.

In the future, if you start to hear bangs, rattles, clunks, and thunks, or dunks, kerunks, spanks, sperts, and blurts, just don't panic.

TL;DR Just turn up the radio.

I reckon I never will understand how you and others ( @Tcoat ) pull off using the Internet so much during work hours.

Back in my working days, communication devices were used solely for business ....... :iono:

1) Most of my day is spent waiting to approve other peoples work.
2) One of my main tasks is to prevent things from going dreadfully wrong but be prepared to deal with them if they do. We do a good job of prevention so I do not have to spend time reacting.
3) I read fast so what appears to be a constant attendance is actually many small 2 or 3 minute spurts. Appearances can be deceiving.
4) If not on here I would be doing something else to fill in the gaps. At least I am not holding somebody else up by standing at the coffee machine chatting.
5) I am the person responsible for monitoring web use. I have no plans on telling on myself.

Well, there you are ........;) ....... oops, wrong picture, that's picture is of @Cole when he is in his office ......:D


humfrz

Close. But more official stuff.

I venture to say that would depend on what else she's doing when she starts to hum...and what you might consider to be "doom".

I'm a traveling auditor based out of my own house, but much of my work is done in the field. I set my own schedule. My manager is 1100 miles away in a different time zone. As long as I keep turning in audits, stay on track to meet my quota and keep my phone and email on during business hours (or at least respond timely when I get an email), my manager leaves me alone. I can actually go up to three weeks without talking with her and months at a time without seeing her. I'm her ideal employee, being very low maintenance while meeting or exceeding my targets. And all of our managers are low-drama and not huge on office politics, at least compared to other places I have worked.

Best job I've ever had.

However, when I'm on the road, it's often balls to the wall to get everything done in the time allotted. It's not unusual for me to work a sixteen hour day finishing one audit and prepping the next. It's not unusual for me to work at night. It's not unusual for me to work on weekends. There have been weeks where I've already put in 40 hours by Wednesday. This was one of those weeks, and quite honestly I don't feel bad at all about goofing off on Friday.

So what you'll often see from me on this board are periods of intense activity interspersed with periods of no activity or just quick one liners. When I'm not here, I'm probably working. Hard. I wouldn't wish for it any other way.

Probably the worst job I've had put me in a cubicle for 40-50 hours per week with a relatively light workload but among people who loved office politics. I used to doze off while still typing in my spreadsheets, then wake up and have to figure out how far back I needed to undo. I moved a plant next to my cubicle in my supervisor's eyeline so he wouldn't see me snoozing. I bought at $1 bag of plastic army men and put them in the plant in a pitched battle against a $1 bag of plastic dinosaurs for my own amusement. He saw them and nearly lost his shit. I hung my mouse up by the cord to let the kinks relax out of it, and he nearly lost his shit. I put a small dorm sized refrigerator in my cube for use by my entire pod for drinks and lunches, and he not only lost his shit, but he ran an inquiry chain all the way up corporate to the Director of Risk Management to determine whether I was allowed to do that. Any time he'd call me into his office, I'd say, "Uh oh, am I in for a beating?" And he'd nearly lose his shit.

I hated that job so bad I eventually just quit, packed up my junk and moved to New Orleans. Len lost his shit when I told him. How could anybody just quit and move to New Orleans without a written plan including goals, objectives and milestones by which to gauge progress?
