Question Interior noise levels of current WRX and STI

Ten years ago I had a 2003 WRX sedan. It loved that car. I ended up selling it while trying out other cars. Stupidly, the first one after the WRX was a 2004 Accord V6. It was just not fun to drive but was a very nice other than that. For my next car purchase, I ended up deciding between a 2004 or 2005 STI and a 2004 GTO. On the test drives, I noticed that the stock STI was MUCH MUCH louder on the interstate than my WRX was. The GTO was nice and quiet. I ended up with the GTO, mostly for that beautiful V8.

So, here is my question. Do current STI's still have higher interior noise levels when compared to current WRX's. I'm sure the old STI tire noise was higher, but there was more wind noise too. Anyway... I'm curious to see what you guys have to say about the noise levels if you have actually ridden in the new WRX's and STI's.

I've only ridden in one of the newer WRX's and I own a newer STi. Both actually had the exact same exhaust system too because we traded, and I thought they sounded 100% the same for road noise.

Why not go test drive one yourself?

I wouldn't be surprised if it was. Though I am surprised the STi weighs ~100 pounds more than the WRX. Never noticed that before. I would assume that's down to the beefier diff, 6spd, and suspension. So maybe the added weight is then offset by sound deadening material.

There you go thinking again.

The newer STI is louder than the newer WRX in certain circumstances. Slowing down from slow speeds, you notice the center diff quite a bit in the STI. On the highway, the STI Dunlops are noisy bastards. Not so much in the WRX. Stock for stock, the STI is louder.

Oh! And sound deadening. Subaru no hablar sound deadening.

Yea I just switched to a subaru after having 3 mustangs and the interior sound is very loud compared to just about any other car I've driven.

That said, if you're looking for a refined, quiet car, the Legacy is what you want. Subaru does not market the WRX or STI as anything other than a fun car to hoon in.

I have a 12sti. The road noise level is high and i really need to have better speakers because the noise drowns out the stereo. Sad but true

I actually had a 2005 Legacy GT. I drive a lot of stop and go traffic now. So, it was an automatic. I installed a transmission cooler and had it stage 2-ish (gutted downpipe) and open source map. Anyway... The Legacy GT just wasn't as much fun as the WRX, but was more fun than the faster GTO. So, it appears that my idea of fun is a lighter car that has pretty decent power.

I'm not going to go look at cars yet, because I'm not buying for a long time... unless I get more side jobs. I'm just researching and don't want the salesman hassle. I'm looking for a similar "feel" to my old 3000 lb 2003 WRX, with the grunt and quiet interior of the GTO. About the only thing I'm seeing that fits the bill right now is the Audi TTS. I would have to buy one of those used, being that they cost just a wee tad bit more than an STI.

I can't wait to see what the next WRX ends up being. We'll see.

The hatches will have more noise than a sedan FYI. Sedans trunks drown out the sound from the rear. (Tires and exhaust)

If I drive more than a few hours on the highway (say to Dallas from Houston) my ears are killing me. Its the road noise (tires?) more than anything.

FWIW I have a Catted DP and Q300 on mine (stock wasn't much better though as far as drone)

I put Dampifier Pro on my door panels and that helps the stereo overcome the road noise so music sounds better (louder). I have enough to cover the rest of the cabin, I am just not in too much of a hurry to tear out my interior. One day I'll do it..I think...

I would say its exhaust and tire noise. Tire noise can also be enhanced by unbalanced pressure or unbalanced torque on lugs among other things. That can also cause tire vibration that's real noticeable or very subtle, but enhances overall noise.
Also depends type of exhaust you have in the exhaust aspect

His question is valid. It is a direct comparison of the noise levels between the WRX and STI models in the current lineup.

Gallo2011 had some good observations.

the STi is going to be louder, it's just a more hardcore car. It's also well known that the 2004 STi (the first release to the states) was far harder than the later years. I've heard even more so then the 2005. My father had one and I loved that thing, it felt like a track car on the street. Loud, hard suspension, hell having a radio was optional!

I miss that car

No no, they totally do, there's metal between you and the road, that HAS TO keep out some of that pesky road noise.

I've been in an 08 STI. No it's not as well insulated as a GTO. The road and wind noise is higher by a lot. In my experience, Japanese performance cars leave little on the table as far as insulation and thickness of panels go. They make up for lack of power with lightness. Both the STI/WRX and GTO are hooligan cars...they just do it differently.

I want my GTO back, wish GM would bring it back as a Chevelle SS or something. They desperately need a GT car. My WRX is loud inside, but nowhere near as loud or rattling as my MINI Cooper S was, that thing was the worst noise culprit....But what a blast the MINI was to drive! I honestly don't think the noise in the WRX is all that bad, the stereo on the other hand is the worst piece of crap I have ever heard.

Wow, a lot of complaining about road noise.

Also, I was under the impression the sti and wrx had the same factory tires, just the sti has 245 vs 235 on the wrx (minimal difference for noise). I guess the STI are lower profile due to 18" wheels vs 17" on the WRX.

I have 245 direzzas on my car and coilovers and I think the road noise is fine. Fairly quiet when my windows are rolled up.

I own a 2013 wrx and a friend has a 2012 sti . Neither car is quiet , even with the factory exhaust . Add an SPT exhaust and you are almost obnoxiously loud . Eventually , u will get used to the road / engine / tire noise and it will become "normal" . They both are great cars but not quiet , comfy cars to drive around in . My other car is a 2012 maxima sv . U can't even tell the car is running sometimes , interior is totally luxurious , thick padded leather seats , thick carpets , minimal road noise . Day and night difference from the wrx , but I still prefer the wrx unless it's a long road trip.

According to TireRack, the WRX is 17" Dunlop SP Sport 01, whereas the STi has 18" Dunlop SP600. Big difference between the two!

Ah, I didn't know that. Well I don't have issues with direzzas which would be far louder than either stock tire. Maybe some people are more sensitive to it.
