focuspwr 03-12-2009, 01:19 PM I know this is a site for the ford focus but I figure i'd take a stab at it to see if i can get an answer. I've been a fan of the WRX for some time now and im able to call it even before its visable based on the low rumble of the exhaust alone.. But now im just curious what part or combination of parts give it that specific sound?

But now im just curious what part or combination of parts give it that specific sound? It's not so much a design of any particular exhaust, it's the fact it's a horizontally opposed engine, vs an inline in the Focus. Very different sounding engine, both intake and exhaust. Definitely a unique characteristic. dirtbrown 03-12-2009, 01:25 PM the motor. focuspwr 03-12-2009, 01:32 PM interesting iminhell 03-12-2009, 01:44 PM Ever nnotice the sound difference from an inline motorcycle to a twin, example RC51 vs ZX-9, V-twin vs inline 4. Same thing applies to the boxer engine's. Also much of a vehicles exhaust sound has to do with the cylinder head design.

And I was SO close to having that sound :( Executionerhk 03-12-2009, 08:45 PM now you guys make we want to buy the subaru Impreza 2.0L LOL mikebontoft 03-12-2009, 08:50 PM opposed cylinders, and likely the header (apparently I've been told that by extending the tubes from cylinders 1 & 3 on our cars by about 2 feet would probably give off a similar sound [;)]) don't remember who said it though, lol. WUGcatsvt 03-12-2009, 09:00 PM You also get a similar sound by taking one spark plug out :) mtadd162 03-12-2009, 09:57 PM ^haha yea and an idle similar to stage 3 cams lol ive actually been told on two occasions that my car sounded like a subby...personally i dont hear it but whatever, not a bad thing http://www.youtube.com/watch?v=5yzm9E7TR4s maybe a lil from like 2-2.5rpm [dunno] dirtbrown 03-12-2009, 10:00 PM ^^^lol at the last 2 posts. myfocusrocks 03-12-2009, 10:09 PM I miss my boxer 6...

And I was SO close to having that sound :( on your fofo or close to having a subaru? mikebontoft 03-13-2009, 06:30 PM You also get a similar sound by taking one spark plug out :) dang it man, was that you with the cylinder #4 misfire?
