closest you can get the CB to sound like an "STI"

[jmolina]

just to let u guys know, its not an exhaust leak

[F22HB]

Running on 3 cylinders, good job.

[Extacee]

spark plug came loose! i know it!

[nine_deuce]

Whatever it is, I think it sounds like shit. And the closest anyone has come to the right answer is his spark plug wires being mixed up, which I'm sure can't be good for his motor, but, whatever I guess??

[rudimentary]

forgot to tighten spark plugs?
forgot to plug a wire in?

I always wondered why do STI's sound like they do?

[edit]: found the answer - http://en.wikipedia.org/wiki/Flat-fo...Automobile_use
"With a piston starting its power strokes every 180 degrees of crankshaft rotation, and the crank throws 180 degrees apart, all the pistons must come to complete stop and reverse before the next one can start its power stroke. This results in a gap between power strokes and a pulsating delivery of power to the flywheel."[/QUOTE]

FAIL. USDM STi's sound the way they do due tan unequal length header design. CIP:




If replaced with an equal length header, Suby's sound
like anyother four cyl
And Jmolina is rolling around with a sparkplug unplugged for some reason....

That is the same thing Accords have.

The reason the STi sounds the way it does is that the cylinder banks have unequal length runs, which results in the exhaust pulses being offset. If you put equal length exhaust components on a Subie, it sound just like a Volkswagen, or any other flat engine, which is to say, much like an inline engine.

But for marketing reasons, Subaru leaves them unequal length to give them that uneven beat.

P.S. If you run an Accord on 3 cylinders, or have bent valves it will sound almost identical to a Subaru.

Is that an Oompa Loompa driving?

Beat me to it.

[Lmolina]

hey guys, this is my car and we did not do this on purpose, we're heading to get something to eat when out of no where the car started to sound like this, started loosing alot of power and we quickly pulled over, we notice that sparkplug number 4 was disconnected from the distributor. The plug was no longer good, so we went to autozone to buy a new set and it fixed the problem

[ibr_adam09]

I was going to say oil in the plugs.


X2 on the 'Boxer engine' exhaust sound, it's because of the stock header. If ya ever check out their forums, there's many threads about people worried if they're going to lose the "rumble, rumble" sound if installing a Perrin Header.
