found one on fleabay. not sure cause it doesn't really state spring pressure or anything. But it's $40, which is good IMO.

Basically I'm trying to figure out a way to tone down the low end pulses on the WRX.
It has a KillerB "holy" header, which flows amazing.
It has a blouch 10cm hotside which flows amazing.
It has a 3", very free flowing exhaust setup which flows amazing.
At WOT and at high rpm, it sounds amazing.

.....but,

At low rpm, I'm talking 1500-2100, I have some serious exhaust pulses/noise that is annoying, that goes away just past 2100rpm.

Fixing those two issues made me not have to install my flapper mcflapflap.

EDIT: I'm interested in seeing your dyno changes if you weld this into your exhaust though.

I too am hoping it doesn't hinder the flow too much

What I'm even more interested in is a 2-bolt 3" electronic cutout so I can place it directly into the stream and be able to open it on commant rather than waiting for pressure to do it, but it doesn't seem like that's a thing

There's a boatload of other cars that would be quieter. None of them meet all of my requirements and criteria, so here I am trying to achieve "quiet-on-demand" in the scoob

Add a "T" right before the muffler, at the 2 bolt flange. Add ~7.25 feet of pipe to the T, with a flat plug at the opposite end. Let me know if that helps...it should for 1800rpm, 800F air.

I can't decide between the flapper and a modified electric cutout TBH
The cutout would let me go "full on race mode" for ALLOFIT spool and transients.

If you go with a cutout for flow, then put the factory muffler back on for quietness.

no no, it wouldn't be dumping to atmo, just restricting on demand.
stock muffler, at this flow/power level would literally fall apart inside and start to rattle like crazy.
Unless I absolutely never floored it without the cutout open
did that with the fxt. stock muffler didn't last long.
it also sounded so terrible it was embarrassing
stage2-ish power levels it would be totally fine though (and what I'd do if I were there)

In the 3+ years ive owned this car, I cannot for the life of me determine if it has a cabin air filter. AC has always been weak, but now it is ridiculous. On full blast it feels like my other cars on 25%.

So, does my 05 legacy GT have a damn cabin filter or not? Or do I have blend door issue or something?

If it does have one, how do I get to it?

Also just took her through emission a few minutes ago. The irony of working at a state run, gov mandated facility while having a 6" diameter, bright red anarchy "A" tattooed on your neck is palpable.

It was optional, mine has it. I replaced it and a/c airflow improved, but it got dirty quick and after replacing it twice, I removed it. Airflow is about 25% improved vs a clean filter, which is enough for the a/c compressor to not cycle as much resulting in cooler average vent temps + the 25% more airflow.

It's near glove box area, I cut some **** on mine to make removing it much easier.

My 04 WRX has provision for one, but it was not installed when I bought the car. I picked up a filter and installed it, now I don't have to clean the dash as often

Right behind the glove box on top of the blower motor, super easy to replace.
