What are you trying to fix? Why all of a sudden?

And the "problem" is only at low rpm, which is really weird. it's a pulse more than just noise. you can feel the pressure, if that makes sense

It's been sitting on my garage shelf since.

I need one real bad.

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.

It's a really quality piece that actually sounds really quiet on any other setup but mine (my setup right now is, IMHO, perfectly maxed out, 10/10 flowing about as good as it can)


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

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.
