How to get that boxer rumble?

If sound is such a concern, will you to be getting a device that makes a "Woosh" sound so people think you got an ubercool turbo?

I already have an ubercool Turbo

I just like the way boxers sound, is that such a bad thing?

[catharsis]

The sound you're looking for isn't "the boxer sound" its just unequal length headers. You would get the same results putting it on an inline 4.

[KeepGuessing]

in principle it works with any engine yes..inline 4 included..

however in application it doesn't make much sense nor does space or logical/sound design allow for the UEL header sound on an inline 4 engine..

Which is why it's still refered to as the Box sound because it's a layout that allows for that type of overlap in exhaust pulses by means of messy tube routing.

I have an unequal length header on my 2.5 NA coupe. You don't get quite the same sound out of it as a turbo motor, but it's close.

How do you embed video here?

Similar to how you tried to do it, but spell "youtube" "u2b".

I think sound is an important part of the personal driving experience. It's why some people sacrifice power for a quieter but more restrictive exhaust. Similarly, it's why I haven't upgraded to a EL manifold on my Subaru. The sound of a UEL EM is, in my opinion, much better. So long as an aftermarket, UEL manifold doesn't detract from the performance of the motor, why give someone shit for doing it?

I was just as afraid of working on a boxer motor before I bought my car, but, honestly, it's not as bad as people make it out to be. Sure, getting to either valve cover is time consuming, and if you ever decide to replace a turbo inlet on a EJ series motor, don't; it's an incredible pain in the ass. It isn't that these motors are any more difficult to work on than an inline or v oriented motor. It just takes more patience. Don't let it stop you from checking the car out.

I personally find it funny on what's in and what's not. The thing is an UEL manifold will always be inferior to an EL header. So if you're going out of your way to spend money and buy a new header sacrificing performance for sound doesn't make sense to me. Function > Form.

I mean really this argument would only ever come up on a subaru forum. I don't think any other group out there is like OMG I NeedZ UEL headers 4 dat boxer sound. Every other group is just out there for the best header for the money. All EL headers too...

Some people don't care about numbers, but this is the internet so if you don't post dyno sheets with every post you make no one takes you seriously.

It all comes down to personal preference.

[dabocx]

EL headers sound diffrent within their own kind. Theres a few good EL headers on the STI side that sound very unique with a porsche like sound. Not as good as the UEL sound but still unique and not like a honda

[Homemade WRX]

All these guys talking about running an UEL for an excuse for broader tq curve by having unbalanced tunes of half the engine, why is there no mention of doing it properly via stepped primaries and tuned tri-y manifold?

I understand some of you are simply chasing the unequel length sound, which is a trade-off though most don't actually understand the intricacies of how the factory has done it for the turbo EJ engines. Anyone ever run an inside bore gauge on them? Ever measured effect length from valve to 'collector'? It is a trade off that the factory made for fitment of the old oil pans and they put a lot of fine tweaks into that cast manifold.

[Lobo]

If I get a BRZ I sure as hell am going to be running UEL headers. That sound is just too much to pass on.

And so what if I drop a couple kw over using an even length system, I will enjoy my car more so thats why I will do it.

Anyway a decent aftermarket system with uneven headers will most likely still perform better than the stock system anyway so it will probably still be a net gain.

Exactly how much HP can one lose by changing the EL headers to UEL? I mean your gonna pay to get less literally, but how much less?
