get rid of it?

if you want the rumble, just get a catless exhaust if you wan the loudest rumble, but if you want to get rid of it, its simple, put all the stock exhaust components back on.

hmm...

i see there is a misunderstanding here.

the STi i saw had a fully modded exhaust. just that rumble was not present when the car accelerated.

the idle itself sounded intimidating.

headers will change it. flatten the sound out a bit. I think it makes it sound better. Someone said that my 02 wrx sound more like a WRC car now, with the headers on.

Equal length headers will def. smooth out the inherent 'lumpiness' of the boxer sound. Equal length headers like the Maxim Works($1000+) and the GPMoto($600+/-) will help to disguise the boxer rumble.

I believe here are some soundclips of a WRX utilizing equal length headers. As you can see/hear, it's not as lumpy..only when it idles is when you hear the boxer rumble.

soundlip 1

soundclip 2

enjoy!

no matter what exhaust you get you will still have the rumble sound, but if you get equal length then it will not have as much rumble sound as much

As people have said. Any (REAL) equal length header will do that.

The GTspec v.III prototypes are going to have a wicked sound. They're the same type of header as the Stone racing header.

Man, that's a lot of money just for a nice exhaust note - good thing it helps power a little too, huh?

Not to change the subject, but I'm still up in the air about the relivant power benefit of headers over stock on a tuned car. The only reason I am bringing this ip now is that I now of 2 STis with FMICs, the same aftermarket turbo, same EM, same shop and tuner, same octane, same boost levels, where the car will stock manifold, stock upipe, stock TGVs, and a TXS TBE with magnaflow muffler made more power and torque (more torque peak and lowend) on a slightly warmer day and 70% humidity compared to the other car's 30% humidity tuning day. The other car had TGV deltes, 4-2-1 headers, and 3.5" TBE.

I'm still waiting for the header shootout that supposedly will be published soon.

Back on topic: I like the unique sound of WRX and STi. I've heard a couple headers that brought the pitch up too much. One actually made the sound of a Civic. I krindged when I heard it. Without a tune, those particular headers added nice midrange according to the owner.
