Right now i have a stock system with 2.25in piping on a 92 legacy n/a. I have a 3a-racing DTM muffler. I was wondering if i could take off or gut the resonator. Right now it sounds like a stock wrx with an axleback. Can i get it to sound like a rally car?

straight pipe.

..but it's gonna be LOUD. It's not the best for long trips, though.. it really is that loud.

Straight pipppp..... wait.... Tristan beat me to it.

How do you have a stock system with 2.5" piping? The stock Legacy system isn't 2.5", it's 2.25"

And the 3a-muffler is going to make it sound like crap, just hack the muffler and run a straight axle back and you'll be fine.

yeah, Phil, I thought of you when I said it. And I did notice that he said his stock system was 2.5.. which i knew to be untrue, as well. i just didn't wanna call him out on it.
It's all good.

Take it off at the header. That'll rattle some windows.

Build your own straight pipe!

haha, scott, isn't that like a re-gift, or something? You've used that before!!

im pretty sure stock is only 2"

my old n/a legacy has a 2.25" cat back w/ two resonators its very loud.

w/one resonator it set off car alarms.

Yea, its been done, but i have a limited repoire and an image to maintain.

Does my car have a resonator to cut out? If so where is it?

It won't get "rally car loud" with the stock piping.

If you want rally loud, and don't care about performance, then just run a 3" straight pipe, and one of those little "woosh" things that they sell so it sounds like you have a turbo.

Greg - Stock is only 2"? Stock for the Turbo's was 2.25" IIRC.

Yea i could run 3" for pretty cheap. My friend had a cat-back done at a really good piping shop for 90$. I could have them make me a custom system for cheaper!

but he has a N/A.

ryno50485,

dont do a 3" on a N/A. you will diminish throttle response and loose some bottom end power.

when i put my 2.25" on w/one resonator in the middle w/ straight pipe back it was waaaay too loud, and it felt sluggish. but when we put a second resonator on at the bumper the sound volume went down and trottle response improved and it felt snappier at lower rpms.

of course that was all butt dyno.

and the stock piping w/out a muffler will sound similar to a rally car, just ask mike wray (legacy PGT here).

we cut all the stock exhaust off just behind where the Y-pipe joins up, yet after the main sensored cat. we cut out the nonsensored cat and resonator that sits under the drivers compartment.

Yeah i didn't realize that 3" would make my car loose bottom end power. I just talked to a friend and he said the same thing you said about sticking with stock size piping. Right now i have a dtm muffler and people say it sounds like a rally car but would it sound different with like a blitz or scoobiesport?

Stock n/a is definitely less than 2.25". I'm guessing 2" or less.

just dont go bigger than 2.5"

conventional wisdom is 2.5" or smaller for small displacement engines.

Just remove the cat back. That'll make it plenty loud.

You can always drill a couple holes in the exhaust, cheap and effective.

I removed my exhaust today.

Well, not completly. You know the pipe that connects from the rear of the first cat? It's supported by hangers (not clothes hangers, exhaust hangers damnit!)

I removed everything after the flange on that pipe.


very loud.


no no, VERY loud.


I have yet to get any complaints from people sitting at lights. It's quite audiable while idling at a light; and no one has yet to say anything to me negative.

Chances are they're wondering how the hell I squeezed a V8 in my little 91 Legacy Wagon. Some also think it sound similar to a harley.


All I know is, for a 4 cylinder; it doesn't sound a damn bit like one of those fart cannon honda/acura cars; I like it very much so.

1. and i hate to be mean but i do belive what your trying to do is called rice.

2. if you want to imatiate the rally car sound. you need a turbo so you can run antilag.

I heard of someone who put a motorcycle muffler on and they claimed it sounded great. Never heard it myself, but it probably looked cool and weighed little. They did it because they got it for free.

Yes, I have to agree here; if you want to sound like the rally car, you need a turbocharger.. wait, well, you need all of the supporting modifications.

the 2.2L N/A stock engine sounds very good when you remove the restrictive muffler; you can do straight 2.25" pipes from the flange before the second cat all the way back and get some nice tunes from the engine; or you can do like I did, and just drop everything at that same flange.

now be careful, some people won't appreciate the loud engine. It's got a very low tone, and travels quite far. Don't do something like put a fartcan on it either to try and amplify the sound.

It's important to remember that the engine in itself is PLENTY loud once you get rid of the restrictive exhaust.

Get a free-flow exhaust system and be done with it.


The only reason I've done it the way I have is because I'm broke; I'm sick of an annoying heat shield rattle, and without the second cat and rest of the restrictive exhaust, I pick up a little power on the high end (and lose a little on the low end; but not noticeable).

Granted, I've exchanged a loud rattle for a thumping thunder loud exhaust note bad enough to set off car alarms; but I prefer it that way.


It all boils down to; do whatever you want to do, it's your car. But if you pull some stunt like smack a two-foot-tall wing on the back and a 5" exhaust pipe; don't expect to garner a whole lot of respect from the subaru crowd.

Update:

Three full days after the exhaust came off, it went right back on; minus rattling heatshielding. It leaks abit as before; but the noise simply rattled my brain far too much.

something else will have to work out in the future.

well right now i have stock header, but just after the second cat it goes to 2.25 to a stock WRX muffler, it seemed ok, BUT its too quiet for me.

but i just ordered a can off e-bay for $30, might as well try it and if i dont like it i can sell it no problem at school and put my stock rex muffler back on.

i got a small one, 2.5inch pipe inlet and 3inch top with the burned effect on it. i am thinking of mounting it strait out or slightly angled.
ill get a video clip when i get a change of my rex muffler and my new cannon when i get it on.

heheh. I have flowed headers, then 2.5" all through, using 2 cherrybombs (resontators that arnt cobys) and a straight thru back muffler.

I didnt used to have the resonators, and my god that was loud. (bear in mind this is a NA). Had to put the two in coz i did quite a few long dist trips and the pandol expense was killing me. But the bark on that was awesome. and REALLY drony.

Has less drone now, and slightly less bark. But still has the nice rumble
