This is from a few years ago. I had my boys hold the camera, so try to ignore the excitement.

From inside the car:

Not really sure how applicable any clip from an actual Subaru will be to the 818 though. I would search youtube for Subaru sandrails and Porche 914s for more accurate clips.

Hey guys-

Just curious what different "exhaust sound" options there might be out there for the Subie flat 4 turbos?

Although I like the sound my STi makes, it doesn't grab me the same way a 911 does. Those things sound like pure sex when you wind them out.

I'd like something a little more exotic sounding than a typical WRX in my 818R.

Header design, exhaust system design, the components themselves -all these influence the sound a motor makes- so I'm curious what all might be out there for the WRX, and what you guys might have run across?

Basically the flat 4 sounds deep and unique only because of the unequal length headers. There aren't many options to make them sound more exotic like a high-revving flat-plane crank V8 or like a screaming flat or V6. Basically they sound like a turbo muted I-4 with equal length headers with only a little bit of unique character.

Here's one of the better sounding equal lengthed STi's I've found: FFD to 1:00 in to hear the sample http://www.youtube.com/watch?v=KThzQw16P5w

Honestly, if you REALLY want the most exotic sound on an 818, just hope the chassis will fit a subaru flat 6. The best sounding flat 6 from subaru was from the SVX IMO

Otherwise, I think we're stuck with the boxer rumble or a regular 4cyl sound. The flat 4's are what they are.

Some of the straighter longer tube headers might give you a more exotic sound. The killer b header has a unique sound... so if you are not feeling the boxer rumble that may be an option.

The H4 sounds like it's missing on one cylinder. Of course, my reference point is a flat plane 3.5 v8 that revs to 9k, so not much else sounds anywhere near that good, but I really don't want an engine that sounds like it's sick. If I build an 818, it will be with an NA motor, preferably H6.

If and when you figure out the issues with mating it to a manual transmission, PLEASE let me know. A NA H6 would be my strong preference as well. :)

Not really issues that I know of, the bell housing for the subaru H6 models are more or less identical to the 4 cyl models. The H6 outback and legacy use(d) the same 4 speed auto transmission as the 4cyl models which the 4cyl model also bolts directly to the manual. Basically it's a direct swap only requiring basic electrical and ECU adjustments.

The MAIN problem on the 818 is that we don't even know the engine bay dimensions and early on, Dave and Jim confirmed that there wasn't enough room in the 818's engine compartment for the H6. That since might have changed.

This has been discussed at length way back in the early days of the forum but here it is again: The Perrin H6 Turbo STI build page.

Go down to the part about dropping the engine in, they say it was as easy as dropping in the stock motor.

As I understood it, all USDM model with an H6 were automatics, so there is no USDM ECU programming to change to to manage the 5mt. PLEASE tell me I'm wrong!!!

I'm sorry, but I'll install a stock muffler before I leave my exhaust with that note. It may suppress a few ponies, but to me, its more than worth it.

My buddy ran an SVX with a 5 speed (2.5RS trans) and one with a JDM 6 speed (and a supercharger). The 5 speed SVX ran the stock ECU. Every now and again it would falter at idle because it was expecting an auto, but most of the time it was fine. The supercharged one ran something else IIRC, like a Hydra. Don't really recall.

Here is the supercharged SVX launching.

Now THAT's what I'm talking about! I think that much power would be a constant exercise is gas pedal modulation/control; and more than I need, honestly, but it was super cool to see! :)

The SVX uses much simpler electronics that the later H6s.

Not to say it can't be done, (because it most certainly can with enough time, effort, and dollars), but the newer H6s and thier electronics will be a challange with a manual transmission.

Once finances are better I actually wouldn't mind pioneering this one.

Like I said, one of my best friends swapped the 5mt into his old SVX. He's extremely active on NASIOC, his sn is GreenMarine

Mechanically there's no issue swapping them, electronically is a bigger issue but you can simply do standalone engine control and be done.

BrandonDrums

10-31-2012, 08:14 PM

I just talked to my bud that swapped the 5mt to his svx. He said he didn't do a thing electronically and it ran fine. H was only the 11th person in the world to do the swap at the time on an svx and it ran like stock aside from an occasional idle issue that was just a small fueling issue.

However, he said the EG33 is too big and too heavy AND too rare to be a viable option. For this type of project you'd want the EG30, EG30R and optimally the EG36R from the Tribeca which at the time of its release was both the smallest and the lightest production 6cyl in the world.

However, the easiest swap would be the early 2000-2004 legacy EG30 which had the older ECU and a separate TCU which in theory would swap right onto a 5mt running its stock ecu and run just fine. The later EG30R and EG36R while lighter and a little more compact had newer ECU's that made more fueling adjustments in coordination with the Auto transmission that would make them not run correctly with a bolted on manual.

However, there are tons of guys with h6 swapped wrx's on NASIOC and they can make recommendations to stand alone ecu's that can use the OEM engine harness. Namely HYDRA and UTEC.

The 3.6r also came on the newer legacy 3.6.

bbjones121

10-31-2012, 09:10 PM

Just be careful, the latest H6's are actually EZ engines, the only EG was the 3.3 liter in the SVX. This is a big difference, as the EG engine is the only 6 cylinder built around the stronger EJ block. From what I read, the EZ engines are thinner walled.

Let me try to get a sound clip of my 06 Legacy GT with borla exhaust once I get my new clutch broken in. I think Borla makes a good exhaust for the legacy. You can YOUTUBE it on both the H4 and H6. The problem is, that even a different downpipe on my car changes the way it sounds quite a bit, so it will be almost impossible to match what cars sounds like with the 818.

For those like me who want to leave it more or less stock (for the NA throttle response and 6-cyl sound), Would that matter? I assume Subaru wouldn't use a design prone to problems.

Guys- let's keep this thread on topic, please. SVX and EZ30 viability are being discussed in 2 other threads:

http://thefactoryfiveforum.com/showthread.php?6122-H6-3-0-Reality-or-complete-nonsense

The aim of this thread is to see if there are any exhausts out there that change the sound of the Subie flat-4 turbo significantly.

Mechie3

11-01-2012, 06:17 AM

Put on equal length headers if you want to change the sound . Pretty much any sound you find though is going to be rather irrelevant to the sound of an 818 due to all the extra piping. The closest you'll come is finding swapped 914 or people running open downpipes (which sound terrible IMO).

Oh yeah. If you keep NA, the newer H6 would be great.

Can we hear the sound of the 818s and the 818r please?

Etos

11-11-2012, 07:58 PM

There's a few aspects one must look into to understand exhaust sounds.

1. Design: The design(Equal length vs un-Equal length) will change the pulsing sound. Equal will have a more evened out pulse while unequal will have longer gaps in the pulse thus the boxer rumble.

2. Material: This is overlooked so much it's not even funny. If you want a deep throaty sound you can't go cheap. Pretty much every header outside of stock for under $1000 is thin walled. While it's enough to not rip apart, it's going to sound rattle canny. The thicker the walls of the header/up pipe the deeper the sound. Hondas are known for sounding like an amplified angry bee hive from their exhausts- my S2000 has a thick walled exhaust all the way to the muffler, it's the deepest sounding Honda I have ever heard in my life and if I didn't know it was from a Honda I would of never guessed.

3. Engine: The biggest thing to change sounds are obviously the heads. I personally know little to nothing to the fine details that the changes to the engine will make to the sound- I just know cams play a big role.

Yeah. I could go through the 4.1 million different videos.

Or in the spirit of open source design I could ask a bunch of (like minded) car guys what cool sounding WRX exhausts they've come across in their net travels. Why re-invent the wheel?

PhyrraM

Because, as already mentioned, the 818 is not likely to sound much like any full-bodied Subaru?

No I'm not [going to have to], because I never said it could! LOL! All I said is that I like that sound. As close to that as I can get is what I will do (within my budget, of course). :) And for the record, my 4 cylinder motorcycle sounds pretty close. It's an inline 4, but I'm hoping with equal length headers I can massage the exhaust note to get the 818 to sound more like what I'm after. Most important for me is to remove any sounds that would make it easily identifiable as a flat 4.

Don't be so sure. My motorcycle is a 4 cylinder and it sounds pretty close.

Since it's been said the 818 will sound different than a WRX, and since no one has an actual 818 yet, this is all theoretical. I posted a clip of the sound I will actually be trying to obtain. I don't if it's possible or how close I can get, but I don't feel it was any more off topic than posting a clip of a WRX with a certain exhaust (since there's no guarantee the 818 will sound the same). Granted, there is probably a greater likelihood of the 818 being closer to that than to mine, but my intent was inline with the original post...

I thought my post was on topic, but you want to be a Nazi about it, that's fine... But I did not post a clip from an F1 car. Mine was from a Ferrari. The difference in my mind is the sound from the Ferrari is achievable on the street; the F1 car, not so much...
