Default stock wrx/sti exhaust

Anyone running an OEM exhaust off a wrx/sti? my buddy is willing to give me his off his 2011 sti. Just curious if it will sound different or be more beneficial/hurtful to the car... Thanks!

now with a HID retrofit


I have a WRX catback on mine. Little difference in sound, that's it. but it's the cheapest and easiest to install option. No drawbacks.
With an STi exhaust, some might argue you'll lose low end torque since it's too large for the N/A engine - but it kind of assumes it's the catback that's restrictive, whereas it could actually be the catalytic converter - in which case, it won't matter much.

I had an STI catback on my 06 impreza. Really didn't like the sound too much honestly. It wasn't deep and sounded kinda ricey. Now I have the STI midpipe with resonator in still and an SRS n1 style axleback(ebay brand-$70 shipped) and it sounds muchhhhhhh better. Really deep and aggressive without much drone.

I've been against STI exhausts as far back as we've been putting them on the 2.5 RS. They always sound raspy to some extent. They will not sound deep or rumbly at all.

Are they cheap? Yes. They work for replacements. I'd advise going against it if you're looking for rumble. If you're just getting it for free or want a different look, then it might be ok. Expect some raspy sounds though.
