Hi, does anybody have one fitted? Any chance to make a short sound video? Thanks!
 
Also interested! Does anyone have experience regarding the quality of the invidia systems?
 
Anyone have this fitted? Any first hand experience appreciated.
 
It’s my exhaust of choice when I get one. I think it’s probably a similar sounding exhaust to HKS’ offering with the Helmholtz chamber. I believe it’s also road legal with the approvals in Europe if that matters to you.

Unlikely to be road-legal in the UK, unfortunately.

Just like any other exhaust that's even marginally louder than stock.

😭

Can you hear it inside the car? (ese off)

You hear that the sound is different in the car, but it's not really much louder. ESE is on, i never saw a reason why i should turn it off.

Well if you can hear it's different with ESE on that's good sign. I have it off as I don't like it ultimately. Maybe should try it on again now I have other (intake) mods...
 
I've got the Q300 catback along with the Q300 front pipe. Only change I made was to weld a 200 cpsi sports cat in place of the resonator in the front pipe since the Q300 front pipe replaces the OE cat with a resonator. I'm currently in the process of also replacing the downpipe and I didn't want it to smell.

Sound is great with ESE on, but personally I leave it off. Mostly quiet (but still louder than stock), but you can hear it when you put your foot down.

Only advice I'd give is to replace the exhaust hangers near the rear axle to something stiffer than OEM. Mine dislodged and fell off at the track :(
Luckily only some minor scratches since I was fortunate that it fell off close to the pit lane and I could pull off and re-attach.

Invidia Australia themselves now also recommend replacing the hangers:

as HJS is no longer offering its opf-back exhaust i am looking for a new one. i already ordered the hjs but the shop cancelled the order :(
so this invidia seems like a good alternative to the hjs. any information about power and torque? any dynos available?
my target was initially to replace the exhaust with one as silent and near-stock as possible and some hp gain (ecu tuning coming end of the year). so its almost all about horsepower in the end.
