2017 WRX STi with an ETS Quiet Catcback with resonated midpipe.

This exhaust sounds killer from the second it is put on and got even better over the first few hundred miles that were put on it. No other engine modifications to the car yet.

Idle volume is honestly similar to stock, but opens up once the accelerator is put down. At highway speeds (55-70mph) there is no drone and passengers can have a conversation without needing to raise their voice.

This is a true 3" catback with quad 3.5" tips. I did purchase the Grimmspeed stock DP to 3" exhaust adapter to prevent any chance of exhaust leaks.

Shout out to Subimods where I picked this exhaust up from, and of course the people at ETS for making a killer product.
