Default 2015 WRX stock exhaust drone

So, on Thursday I got my 2015 WRX and I'm really loving it let me tell you but there is ONE thing that I do not like at all...the OEM exhaust drone. YUP, right out of the factory the OEM system drones.

At idle and around 1.6-1.8K the exhaust is frankly obnoxious. I'm all for a nice sounding exhaust but there is NOTHING sexy about the hum of drone.

Thankfully, it's great on the highway cursing but in those two areas listed above it's pretty prevalent and not a pleasant sound at all.

My exhaust taste a sexy idle burble, not loud crackle crackle pop, ZERO DRONE at ANY REV RANGE, quiet cruise, and an angry warning to others when at full throttle lol.

Is this something that goes away over time, for 2015 owners, or is this just a characteristic of the system from Subaru?

On the G8 board folks with drone would put in a j-pipe to fix it, have any of you thought about that?

Based on my likes, do any of the axle back or cat back systems out there match up with my wants with ZERO drone?

I might take a video and post it up.

You should have got a CVT, no drone. Looks like you're gonna have to trade it in.

Just go back to unequal headers. WRXs with unequal headers NEVER drone.

They just go rumble rumble rumble.

I'm sure if you got a mid pipe from an 11-14 with the resonator that would probably fix the drone issue.

Really? Isn't the factory catback pretty much the same between the two except the missing resonator and adjusted hangers on the muffler? Hence why some 11-14 catback fit the new ones

The mufflers won't bolt to it, the connections are different, you would need the full catback which would probably kind of fit

Uncle Scotty, don't bother posting...your on my ignore list. Like bee's to honey...I just added a few more to the list, the jackass population on NASIOC is the highest I've ever seen on a forum...thankfully nothing an ignore list can't fix.

Life is too short to waste it on folks like this...

Anyway, I did post pictures up on the 2015 WRX picture thread FYI.

As for the drone, anyone with an aftermarket exhuast please chime in.

Yay! You finally got your car. Still waiting for mine. ._.

I've heard very mixed feedback about the drone in this car. Makes me a little worried cause I hate droning too.. Wonder if someone will make a good sounding exhaust without drone... *waits patiently*

Thanks man! Yes, the car is fantastic and worth the wait so hang in there...but I am sad to report it drones at those two points pretty bad. At least at highway speeds (the area where drone is the most annoying) you are safe from drone.

I hope there is an answer to this because it's annoying. Not enough to ruin anything but enough to invest money into to correct.

Don't know what you want. If if bothers you sell the car. If you want to keep the car and fix the issue take it to an exhaust shop and have they try and come up with a solution to what you're looking for. I can tell you one thing and that is Subaru isn't going to release a warranty drone free exhaust so you're on your own.

Here we go....

I'm not looking for an answer from Subaru, selling a car I love but have ONE real complaint about is as rational as an overly emotional woman.

Is this not a forum? Isn't this the place to bring up things we feel are issues? You mention a complaint, not so much you but the others posting here....and the fan boys come out like trolls under a bridge asking for your head. Again...life is too short to waste even a long response on...not you, the others, but YES....I don't like it and I'd like options on fixing it.

Isn't that why we mod things anyway...to make it better or fix things we don't like???

Geeezzzz....the only valid complaint around here is the ones that bother self, not others.

I'm not experiencing any drone. Maybe a little noise on a cold start, but then nothing. Silence.

Maybe it's because I'm used to my old WRX which had a turbo back and EWG. If you think the stock exhaust is loud, I wouldn't try any aftermarket exhaust.

So like a forum you clearly chose not to read my second part or even care to entertain the option of processing. There is one option for you. Go to an exhaist shop. There is one person who hates the drone and that's you. Only you can be the one that says it's ok or not. Someone else saying they put on a cat back and they were fine still wouldn't mean anything since maybe your ears or body could be more sensitive then everyone else. It's almost like a "my car is making a noise, tell me what it is" type thread.

You need to confirm whether the obnoxious sound you hear from your WRX is present on all new WRXs. It seems like a Subaru dealer would allow you to sit in a new WRX that is just idling. If the new WRX sounds OK, then maybe your WRX has an exhaust leak which could be fixed.

I get the drone the OP is talking about every day at startup/warmup and it's a legitimate concern for some. It resonates through my garage into the house, but it is what it is for me. I've got a Nameless exhaust on order, not to address this particular issue, so I can't provide any suggestions quite yet.

I must say, to see the same five trolls ****ing up every thread, sure is tiring. Please go do something productive with the your life to help the human race, if possible, instead of upping your worthless post count.

The wrx has a box-looking resonator in the DP and lacks one in the midpipe. The STi midpipe has an inline resonator.


Solution:find an STI owner who wants a louder exhaust for free. Swap the pipes.

In a perfect world that sound wouldn't be there. I have a CVT WRX and have it, too... but it is a minor transitional sound in the bigger picture, where the overall sound is great for me. As noted, it does not drone during cruise which is most important.

Further, the word "drone" needs some inspection. That is, with the perfect cadence of this engine's exhaust being a "tone," as opposed to most Subarus we are used to, there is going to be a resonance somewhere in its spectrum. That's how resonances work. To eliminate resonances entirely would have produced an exhaust no one would have liked.

Outside the car the sound is quite nice, IMO. I've listened as other people drove my car, and it sounds good to me, fitting the image of the car. Whatever resonances the exhaust has is purely a personal opinion based on being an occupant. Same with any other aspect of the car's sound footprint, which I personally like, btw. Wife, too. Some focus on the ELH sound, some on the faux CF, some on color, some on Corollas, LOL. For you it is a fractional component of the exhaust note.

Think about it... from an exhaust engineering perspective. Every aftermarket option only increases decibel levels. A midpipe resonator only works on the spectral components that affect cruise. That Helmholtz trap you mentioned would require extensive, expensive, trial and error testing... with the likelihood of success, without consequential issues, a low probability.

It's like the scratch you're going to get, or the chipped paint on the hood... no need to repaint the car. Everyone has something about everything in life they have to put into perspective so we can get on with the enjoyment of it.

I will say this as a tossing of corn over the rail to the trolls it's always been my unspoken opinion that a MT '15 WRX would probably suffer more exhaust resonance issues than a CVT WRX. Must be.
