The Perfect Flat 4 Sound
Does anyone know what exhaust or what exhaust gives of this type of sound.
I know the Ninja 2 and M2 exhausts give of a Deep Burble, however do you think this guy has got unequal headers to?
Help much appreciated.

Thanks guys for your input, but i've heard all the exhausts mentioned above, nothing quite matches that forester. that sound is something else.

definitely got unequal headers. Id agree with the above, sounds a bit Nur Spec'y. Or perhaps it's just a straight through with no rear box?

The SG9 forster sti does not appear to have equal length headers , a delete mid section plus a sports box gets a very similar effect to the video , which even as an owner does sound very good

People sometimes think JASMA is a brand. JASMA is short for "Japanese Sports Muffler Association". Its a certification given to exhaust systems if they complys with certain standards they set, it is not a specific type or brand of exhaust. FUJITSUBO, Blitz etc all comply with JASMA

I've had the following exhaust setups:
1. MY00 UK Turbo (OE headers throughout):
a) standard DP, 2.5" non-reasonated centre pipe and the original Prodrive backbox
b) standard DP, 2.5" non-reasonated centre pipe and a Ninja 2 backbox
c) sports cat DP, 2.5" non-reasonated centre pipe and a Ninja 2 backbox
2. Version 6 STi:
a) GT spec headers, de-cat DP and 3" Apexi N1 system
b) GT spec headers, sports cat DP and 3" Apexi N1 system
b) ported OE headers, sports cat DP and 3" Apexi N1 system
d) ported OE headers, sports cat DP and 3" Blitz Nur Spec system
Thoughts:
1. a) Pleasant but far too quiet (a de-cat with this system might have been nice)
b) Lovely - just what I was after in all honesty!
c) A slight(!) improvement over b)
2. a) Obscenely loud and raspy...embarrassingly so! Really didn't like the GT spec header sound.
b) Moderated a) slightly
c) Huge improvement, generally very nice but lacking the lowdown burble of my previous car (sounded better further up the rev range though!)
d) Very deep burble but annoyingly loud, boomy and intrusive - nowhere near as bad as a) or b) though
It could just be me but IMO, based on my experience, 2.5" sounds nicer than 3". With the right system you can get a lovely low down rumble that's loud enough to sound good and get some looks but without being embarrassing or off-putting on longer runs.

my 1st impreza sounded the best, it was a blob wrx with sti engine/gearbox and had the following exhaust
-heat wrapped de-cat 3" japspeed downpipe
-heat wrapped rcm headers and venturi up-pipe
-3" afterburner de-cat center section de-resonated
-afterburner raptor angled backbox
it popped and banged and crackled on over-run and on full chat sounded truly awesome. had a lovely deep burble on tick-over.
i put an afterburner 3" center section and raptor box on my current hawk 2.5 sti with a de-cat downpipe but it didnt sound anything like my 1st one. would a set of gt spec headers really alter the sound of the car? its the only thing thats different.
