Check out some custom exhaust shops, depending on where you are based.

Hi Tech in darlinghurst, liverpool exhaust, some other places too.

You can eliminate most unwanted noise through resonators.

Just try to source a system that is 2.25 inch or 2.5 inch in diameter.

In my opinion - get a set of extractors, highflow cat and keep the stock rear muffler (apparently they have reasonably good flow and are fairly quiet - from memory it is claimed they have better flow than a WRX's muffler...). I have this setup in my car and I'm quite happy with it - Quiet at low revs once you reach above 4500rpm the sound is awesome, similar sounding to a BMW 6 cylinder - Automatics with loud exhausts at low revs don't sound great.

sounds pricey...but thats exactly what im after....low revs=low noise, high revs=grunt

so i should throw the original back on? kinda heavy.....

Yeah, the genuine item is heavy, but i suppose it is the cheapest option for low noise as you already have it in your possession. :D

The setup in my car was already in place when i bought it so I didn't spend anything. The other great thing is that the stock rear muffler will not attract any unwanted attention.

sorry to hijack this thread...

just got a resonator installed on my exhaust system yesterday to reduce the noise. (down to 88db now :ermm: )

i had my doubts but after hearing it it was actually worth the money, a much cleaner note now imo, and its legal :P but one thing im not sure about, will it have reduced my power at all? i know that generally, the more mufflers etc you have on your exhaust, the more limiting it is...as it stands i have stock exhaust with the new resonator and a muffler, and a blitz exhaust tip that gives the throaty roar :thumbsup:.

eventually id probly wanna upgrade to a completely fresh system anyway, but for now this should suffice me...just wondering about it is all.

cheers

i not sure if the stock item would flow that well.......mayb get a turbo stock muffler that may do the trick for an N/A

Flow and noise are directly related. If you want flow, scrap the muffler and get a straight pipe - but it'll be noisy as all buggery. A big fat muffler will kill the noise, but kill the flow too. Basically the more you have in between the engine and exhaust tip the quiter it'll be.

Turbo's get away with cannons and the like because the impeller wheel up close to the engine mutes a lot of noise, but NA's don't have that, so a turbo spec muffler will make the noise problem worse.

I thought they were the same stock rear muffler between the turbo and N/A...... :S

They're not the same. I have a stock N/A system and a stock turbo system and they are quite different in size.

I have yet to fit the turbo system but when I do I'll post up some picks and a bit of feedback. :domokun:

*edit*

I also have a Fujitsubo Legalis R cat-back system ( on my car at the moment ) and although it was a bit "$" it sounds awesome ! At idle it purrs, on cruise it's silent and when you get up it, it sounds like a BMW M3.

Might be worth considering since it sounds like exactly what you're after ( unless you're on a tight budget ).

Only reason I'm fitting the stock turbo system is to experiment. Don't know what I'll do if the stock turbo system turns out to be a winner :domokun:

OK so I finally got around to fitting the stock turbo system. Here's some pics to compare stock N/A to Turbo systems.

Flow is good but sounds like crap. Same tinny sound all stock systems have. I think I'll be keepin the cat-back but might throw a different rear muffler on the stock turbo system and see how that sounds.

Anyway, here's some pics of the Fujitsubo system vs. the stock N/A system ( in case anyone's interested ).

    • You're not the first person that's said that about this car lol. A Touring wagon GT in Spark yellow mica would be the dog's danglies 😆 I will keep an eye out for a future purchase for sure. The seats are almost like the OEM Recaros... electric adjustment for fore/aft and tilt movements except reclining.   
    • Yes!! I love these! It's a shame its not the wagon though!   Thank everything that's holy that it doesn't have the interior of the Aussie delivered ones. Those seats are so much nicer.  
    • I'm both sorry and thankful that you do that. 
    • 2001 BE5D Subaru Legacy B4 RSK (3rd gen) EJ208 (pink injector) Twin Turbo 280PS 5-speed manual Full time 4WD "RSK" grade which means all of the above LQC option which means stock rear spoiler  I got it primarily to export to someone outside Japan who was interested. These BE5 Legacy B4 RSKs are going through a bit of a resurgence right know in Japan as they are one of the few cars from the "turbo, manual, RWD/4WD, 280hp gentleman's agreement era" cars that don't require stupid money to purchase. Which for some people might be a good opportunity to get as a base for restoration. If I can't find anyone to purchase it I will certainly be doing that myself over the long term. Why? Because it's properly fast in stock form, handles well enough for a GT sedan, there's still enough aftermarket and (if you can wait a while) genuine part support to make it a restoration candidate (<-- that will only get worse over time so it's a case of do it now or choose get a BL5 4th Gen). Mechanically it's fine, has only 89,200kms on the odometer. The problem with this car is that the body and exterior trims are weathered from at least the last 10 years being parked outdoors. I'm the 3rd owner, the first owner was the one that had it for 14 years and barely drove it, had a low-speed front impact (which didn't damage anything behind the radiator support) and got it fixed and sold it. The 2nd owner put most of the kms on it and parked it outside for the last 10 years, hence the door rubbers have seen better days but if you overlook those cosmetic details, it presents pretty nicely. There is some minor rust on the LH rear wheel arch which I'll have looked at too at some stage.  Also as you'd expect from a car this age, the clear top coat is gone, leaving a satin finish on the roof.  Mechanically it's fine (as you would expect from a car with less than 100K kms) but the steering does feel slightly vague around the centre position at higher speeds. So first on the list is to get the steering rack bushes looked at. There's also the Lock button on the remote which doesn't work, but the Open button does.... it means that the anti-theft system thinks it's always open? It seems like if you open the car and don't start the engine within 3 mins or so the anti-theft kicks in again without any beeps or signals. So if you got to start it after that, it won't. You have to push the open button again. That's how I understand it anyway. Just a small irritation but not a big problem to sort out. There's only one mod, the Wangan SPL muffler. Just a tad louder than stock. It's a really good mod for those who don't want to wake the neighbours but still want to hear a more prominent unequal length header EJ20 sound. Anyway I hope to get all those things done eventually, that is unless someone wanted to import it to their country from Japan (where I live). I'm open for negotiations as I really would like a Skyline... but this will definitely suffice in the meantime 🙂 *Disclaimer: This is how I picked it up from the dealer, minus the stuff on the back seat. I haven't cleaned the engine bay or done a thorough exterior clean, aside from spray painting the wipers. 
    • Wow, even with the Audi logo centre caps. I love OEM wheel mismatches.
