I'm having this problem where my b16 sounds / feels like a subaru motor. The first thing I thought was misfire or a weak cylinder, but that is not the case. Here is what I checked so far:

Spark plugs: All 4 look perfect, same condition
Leakdown test: Perfect.... somehow (i was amazed)
Compression: Cyl 2 was 8.3% lower than 1, 3 and 4 (does this throw up a flag?)
Cylinder balance test: All 4 cylinders dropped the same RPM
Injector clip continuity / resistance to ECU
No burning oil, no missing coolant, no vacuum leaks.

Its a totally stock b16 with an intake and a megan header / 2.25" exhaust

According to all tests, all 4 cylinders are running fine. The motor seems perfectly healthy and pulls hard with no smoke, it just has that subaru stumbling / misfire feel between 1 and 3K rpm. Above 3K it smooths out. My girlfriend says my car sounds like an airplane! I am stumped! Anybody have any other ideas?

Mine did that when I bought it. It had an OBX header and some kung fu 2.25'' exhaust. I think it's a characteristic sound of the header and exhaust. Mine also felt sluggish at low RPMs....more sluggish than even a B16A should.

Try checking your ignition and cam timing. The culprit for mine was that the ignition timing was too far retarded. I think the T belt was stretched. I just changed the T belt...and have yet to re-check the timing.

thats funny - i have the cheap ebay megan header and cheap ebay 2.25" exhaust. i havent checked the timing.... i will do that, thanks. it does feel like it has a lack of torque and and sluggish at low rpm.

well good thing you got that figured out. i have a dc header and a apexi ws2 exhaust and its nice and quiet in regular driving (and doesnt sound like a wrx). you might want a better header like a hytech or hytech replica even, i've never heard people having problems with those.

my friends em1 sounds the same way he has ractive headers and tanabe catback exhaust.........

the sound you are hearing is from water geting in your distributor most of the time u can just take the cap off and wipe it out and see if anything is rusted
