Default 2012 Impreza, unbolted muffler sound

I thought I'd unbolt my muffler and see how it sounded straight.

Sounds like your typical WRX after the usual exhaust mods. Is the rest of the exhaust still stock? Surprising how much of a difference the muffler makes.

Everything is still all stock, just took the to bolts out of the flange and revved her up. I might just put a down pipe welded to another flange that i can switch between muffler or straight, in case the wife complains too much

Yes. Mufflers are mandatory, any many mufflers are not street legal.

^ Not exactly... at all. Some vehicles are even built without mufflers (Neon SRT-4 comes to mind). It depends on local and state law. Where in the Northeast are you? Mark W.

Most muffler shops will do a muffler delete for pretty damn cheap. As far as the legality of it, I have no idea.

Isn't the muffler just to "muffle" the sound. Most states or towns/counties have decibel limits for street use cars.

I found this on another forum:

I have done a little research and found that SEMA has suceeded in rescinding bogus modified exhaust laws at the state level.
For those of you not familar with the law, washington state RCW used to be a copy of the Federal one, basicially stating that you couldn't modify your exhaust from stock- OR- it wasn't to be above 95 decibels per SAE test standards.(which btw-is 50ft back and to the side IIRC-not shoved inside your muffler). Washington's legislators took it upon themselves to simply remove the decibel limit and the "OR", leaving it to the cops discretion if the exhaust is too loud. Many of us have discovered that it seems to be if the exhaust is too big or too shiny, not necessarily loud, and that imports generally get picked on while trucks and harleys with straight pipes roll by unbothered.
Several state's have placed additional restrictions on the decibel limit, reducing it to 80-85 decibels, which is totally acceptable to me as there is a limit given to meet. Unfortunately imports are profiled because statistics show there is higher probability that the driver is DUI, no insurance, suspended, etc. I can understand using the modified exhaust excuse to stop someone and check them out, but to have the law with no sound limit is set up for no other reason than to TAKE YOUR $$$$$.
These changes were brought on by some "california immigrant" state troopers who have seen "fast and furious" too many times. All engine swaps, headers, cold air intakes, and even changing to a different transmission is illegal to them. We are all street racers, thieves, chop shops, and gang members and are guilty until proven innocent. They will not rest until all the import shops, engine importers, and speed shops are closed up and gone, and we are all driving white-automatic fords or chevy's bone stock with low air pressure warning tires.
I have also discovered that this RCW, lacking a defined noise limit, could be considered vague and therefore un-constitutional. Anyone ticketed who's exhaust wasn't over 95 decibels could be entitled to money back in a massive class action lawsuit if this proves true.
I invite everyone and anyone to write Sema at sema@sema.org
and contact the Governor-not that she'll do anything-but maybe if enough of us write..... at http://www.governor.wa.gov/contact/default.asp
Tell them about your "experience" with getting stopped/ticketed for your "modified" exhaust.

Please don't do a tacky muffler delete. If you want a louder exhaust get a new, louder muffler.

Obviously there are laws in place to allow the collection of money and to prevent disturbing the peace. Are they ever hypocritical? I think so, since decibles for stock exhausts are set as vehicle specific limits which exclude my neighbors Harley. Regardless, you don't have a say in the matter. Setting up a straight pipe that sounds like a dinosaur ****ing a fog horn on a street driven car is like waving a banner that says pull me over. Removing your muffler visually won't help your case either.

Your call nevertheless.

So. $300+ for an exhaust. Or $75 for something that will provide the same function and very likely save more weight than adding a different muffler.

....and when cruising they sound the same. Also looks stock.

"RICE" isn't a reason. It's a term that gets thrown around a lot.

Muffler delete isn't rice. A fartcan is rice. Muffler delete, as long as it's not obnoxious, and doesn't just end at the end of the midpipe, under the car (to collect fumes), is a solid mod.
Again, check your local and state laws to find out about mufflers and sound levels- Mark W.

No, a muffler delete is definitely rice, and they sound very bad as the muffler adds refinement to the sound.

Not necessarily. As 420 said, Subarus sound good without mufflers. Not really a matter of opinion, as almost all aftermarket mufflers for the WRX tend towards a straight-through design, which doesn't reduce the SPL that much. Mufflers don't add anything to the sound- they take away- that's their job- Mark W.

If you have "rimz" yes. If you have wheels, then you have the benefit of the doubt.

Haven't been around modified cars much have we? A lot of these straight thru exhausts also have resonators that help deal with this issue. Go listen to an N1 Race and then an N1 Street (or better yet, compare it to any of the standard muffler exhausts such as Cobb, TurboXS, Stromung) and tell me you still think the N1 Race still sounds better and that the only difference you hear is the volume.

If you care to read my post you'll realize there are more than opinions at work and this has absolutely nothing to do with the cost of k00 mods.

Let's say I'm a cop following your loud car. Am I more likely to pull you over for the obvious, abject lack of a muffler or with? I don't really care if you agree or not, neither your wallet or driving record are my concern.

If you would also care to explain how removing your muffler looks stock, I'm all ears

This is the same car in the video. Looks stock to me. An officer following you would not be able to discern between an aftermarket muffler or a muffler delete unless they got out and looked under the car. Even then they would need to be familiar with the car, as the resonator pipe could resemble a muffler.

Obviously if you are in a city or county that are nazi's about exhaust you should keep the car bone stock.

I just disagree that deleting a muffler is rice is all.

So you define rice as the terminology someone uses to describe their wheels, as opposed to the style of the wheel itself? Seems a bit judgmental.
