If you never plan on getting a catback (or downpipe), the Muffler Delete (W/ 4" tips) sounds good, doesn't drone very bad, and adds a nice tone. Once you add the rest of the catback or a downpipe, the muffler delete goes from mild to wild, it's very harsh, and very loud.

 

Muffler deletes will get annoying very quick. Go with the 4 inch muffler, and 4" Tips. My last two exhausts were 4" and they fill up the exhaust openings completely and look mean.

 

Muff delete are obnoxious. They don't sound good just loud.

pics and sounds plz

 

and what will my dealer say about that change being under warranty and lease?

 

I got the muffler delete and it isn't as loud as I thought it would be. It sounds pretty good. It will not void your warranty because its just axel back. You are literally just swapping your stock mufflers for straight pipe.

 

I'm not sure what you consider loud but I have been around plenty Subaru's with deletes. Including the newer ones. They are loud as crap. Loud enough that they easily violate our 95 dB sound limit

I haven't heard an overly loud 15+ WRX. The Nameless axel back sounds just right honestly.

 

Then your opinion of loud is skewed. The guy I bought my car from has a 15 with muff deletes and you can hear that car over a mile away. Quite literally you can her his car at the bottom of my road that is just a tick under a mile from me, it also winds through the woods. He also got countless tickets for noise.

Our local ordinances are set at the "causes hearing damage" level. So if he is failing, so are his ears because he feels the same as you.

I've also heard a couple FA WRXs now that made me think..."I'm definitely not going with that setup!".
They sounded like gurgling metal farts. I firmly believe a cheap-o solution to the exhaust cheapens the car dramatically. Why would you want your brand new WRX to sound like an 80's K car with a hole in the exhaust? Unfortunately for me I know exactly what that sounds like.

 

So do I. I drove a Dodge spirit for some time with the go to hole just before the muffler. It is legitimately the same sound, that sound is bad.

That video clearly demonstrates the eBay exhaust in a civic sound I was mentioning and the obnoxious tin can effect. Thanks.

To each their own. Video was for OP

 

Muffler deletes effectively straight pipe your car minus the cats. It's cool at first but gets obnoxious very quickly during commutes. Not to mention here in Cali you're constantly looking over your shoulder for cops due to noise.

 

I have the nameless muffler deletes on my 2011 wrx sedan with no other currents mods other than a stage 1tune from j@m and it's not that bad. At speed it doesn't drone at all. It's only loud when you want it to be, ie;when stomping on it, then it's pretty loud but in cabin just isn't as bad as I thought nor as some folks I have heard describe it. It's louder but it sounds amazing and doesn't drone. With a dp it sounds even better. I think the 4inchers for me would be too quiet. My wife doesn't think it's loud in the car, my kids don't think so, they all just think it sounds good..lol so take it how you will. Louder but not annoying in the least

I agree with the other guys, in that "muffler deletes" just do not sound good on these cars.

jdidtht, I had the nameless Axle Back "Deletes" on my '11 WRX with no other mods as well, and then I swapped out to a catless downpipe and it was ungodly loud. Honestly loud to the point where I think having kids in that car would've caused permanent hearing loss.

I know "loud" is a relative term, but as owners get newer and newer, It seems everything but an open downpipe is "too quiet" to too many people, ha.

 

Lolol I respect your opinions. I think the nameless deletes sound ridiculously good. With a dp it accentuates the lows but gives you the clean upper end as well. Sound in cars is all relative and completely opinion based until a person starts measuring decibels. OP should just go with the 4" if he's at all concerned about the overall volume of his car. I daily commute 1hr each way every day and my nameless deletes to me, made my drive that much more fun.. we drive it everywhere of course and we all enjoy it. Wife background is dad with hotrods, classic cars etc etc so it all fits in. My buddies sti sedan with the same exhaust and cobb catted dp sounds amazing and inside the cabin is relatively quiet, no need to raise voice to chat or anything. It's only loud when you want it. So, I'm going invidia catless ,so I expect more sound then he has but overall I dig it

If you want a preview of how it will sound just poke a giant hole in the muffler or just cut it off.

I guess you could just unbolt the stock axle-backs...

 

Yeah, but if your going to do it right, you are not going to want a muff delete.

I understand exhaust sound is a personal thing. However annoying is wide spread. Seriously, there is no youtube video that will tell you anything. I used to want muff deletes on my 550i BMW until I actually heard it in person.

There are amazing exhausts out there that sound phenomenal, have a volume you notice without alerting everyone you are coming from miles away. I would even recommend the n1 over a muff delete and it isn't much better, it's still obnoxious and fart cannon sounding.

Mufflers and resonators are designed to quiet undesirable exhaust noise and amplify the good stuff. Removing one of them just leaves you noise

I still don't think its loud enough to be obnoxious. Maybe because you know its a muffler delete when you hear it, it bothers you. Anyways for OP if you want something that's a little louder than stock Id go for the muffler. If you want something that's louder than stock and more noticeable get the delete. If you want my personal advice, what I would do is save another 400-500 bucks and get the Tomei Expreme Titanium Catback. It sounds amazing and will you a little power boost unlike the delete. Good luck.

Don't spread misinformation. Catbacks do not change the horsepower, at all, on WRX's/STi's. Turboback will.

 

It just depends on what OP is going for. If your going for that "sense of occasion" like driving the car is something like a special occasion and you aren't worried about this or that then just try the deletes, nameless is a couple hundred bucks for the deletes, you don't like them I promise you could resell them in a week to another guy, for sure, or if you are just wanting alittle something added to your sound then go the 4"route. I think of it like a Ferrari or Gt350r or something that has a sense of occasion to it, like driving the car is something to be enjoyed and special so I want the sound, anyone who hasn't rode in a car with a nameless delete has no idea.. it's just not that crazy. If your talking twin straights out the back yea, that's going to sound different for sure and I wouldn't go that route, and as one user stated just drill some holes in your mufflers won't give you a good idea for sound other than what a ****ty exhaust leak would sound like. Their are certain frequencies that aren't in the car anymore that at lower rpms with the stock exhaust was a definite drone, they don't exist with the nameless. Their is no drone. But, it's either quiet or not quiet, but not crazy obnoxious. These threads are pretty subjective and your not really going to get a clear answer until you ride in the set up your thinking about. That is the only time you'll know. I also somewhat disagree with the you can't get any real info from youtube. Yea most videos sound quality is bad, but a few out there aren't. You can get an idea of tone anyways, but like I said, you literally have to try what your thinking or find someone with the set up you are thinking of to really know what your in for.

I can tell you without any doubt a muffler delete in a 15+ is in excess of 95db. That is our city ordinance and the previous owner of my car that has 2015 with muff deletes gets tickets regularly for it. I cant remember if it's 15 or 20ft they check at, but that's loud. Loud enough to start causing hearing damage. That's louder than a Harley, they typically clock in around 90 with an aftermarket exhaust.

It doesn't matter what you think your hearing in your car. Your exhaust is loud as crap.

Sent from my Nexus 6 using Tapatalk

 

Okay bro.

Sent from my SM-G935T using Tapatalk

 

Facts are facts. Your opinion is not a fact. 95 db is hearing loss level. The car is exceeding that, and judging from what I hear at work and knowing the ambient levels there I venture a lot a good 5 or so more. So the sound deadening in your car helps a little and you get down say around 90 or so, but everyone else outside of your car is not amused.

The interior of my car is NOT 95db at any point. Behind my car, **** ya 100+ I'm sure. Don't care. But if interior sound isn't a concern to someone then this is an irrelevant thread, it needs to be considered. You don't know me, or my cars decibels so your "facts" are indeed also heresay which is opinion. I'm surprised folks are getting butthurt in a thread asking for advice in regards to exhaust . Lol 98% of subbie forums I'm in your minority.

I know is just an app on my s7edge but 80 is wot in 3rd and the other is at 70mph cruising no radio or conversation inside of course the 85 was my wife yelling to see how loud she could get it. Lolol outside in the back far louder but the point is, it's only loud as hell if you are stomping on it. Driving nicely no cop here in Minneapolis even looks at me, in any car your rodding around in will draw attention. Southern states and others may differ greatly but never had any issues if you drive responsibly where you should
