i've been searching a lot in a-zine and also youtube, looking at some videos/sound clips of greddy evo 2 in different cars

I am really looking for that growlin rumble noise,

and i understand with the boxer engined STI or WRX 4 banger are good at making that sound, especially with Greddy Evo 2

I know TSX with greddy evo 2 give low sound, but no rumble really.

I was shocked when i listened to a na 4 banger TC engine, which is vvti 2.4L (same size as our TSX), DOHC but only 160 hp.

that TC with no mods had GREAT rumble sound with jus Greddy Evo 2 installed.

how does that work or how can i make my TSX sound more rumble

The boxer engine in the Impreza is by nature going to make a very unique sound. Porsches, Subarus have this configuration, and their exhaust notes are unique by nature, since they are horizontally opposed.

Someone my know better, but I don't think you're going to achieve that particular sound with the TSX.

yea i agree with the unique sound of boxer config.

but another question i addressed is how come TC with similar engine config ( 2.4L, 4 banger, 16 v DOHC with even less hp) make better, or great rumble noise

Just how their exhaust is setup is aw my friend's tc the cars smaller so i guess their drone or growl is in a smaller exhasut system.

Honestly the vidoes don't do any justice to most of the exhaust. hear it in person if you can most people love their greddy evo2
i love it everytime i hear someone with it at a meet...

I would trade my fujitsubos or sell it for greddy so thats my 2 cents.

The TC may sound a little different since it's single exhaust.

PJS

Manifold tubing diameter, length, and shape plays a role in sound as well, so not all 4-cyl engines will sound alike.
Similarly the shape and diameter of the CAT-back, plus the back-box design and fill material.
In other words, many varied factors make the resultant sound, not just one or two things.

With header, cat, and exhaust you'll get what you're searching for

It's not the boxer laybout. It's the header/manifold design like what PJS said. When the Liberty GT came out, there was no boxer rumble even when it was the same 2.0L boxer turbo like the WRX.

It is true that the unequal length header/manifold design on the Impreza is what gives the rumble. If you swap in a equal length header, then it will sound like any other Acura/Honda.

arhh i've been waiting and saving up for Greddy,

but i was recently informed that Greddy is not selling Evo 2 anymore, mainly because its hanger would rub with our bumper and etc.

No wonder i called ~6 to 8 shops and also ebay to find this Evo, and EVERY single shop said it's backordered.

man....Greddy Evo2 was my favorite exhaust for TSX. maybe i'll jus wait for another exhaust.
