Invidia Q300 Twin Outlet Rolled Titanium Burnt Quad Tip Cat-Back Exhaust | 2015+ Subaru WRX / STI

For a stock FA20 this is barely louder, won't upset your neighbors. Combined with the maperformance j pipe it growls nicely when you're on the throttle.

It looks beautiful with the blue tips and sounds beautiful. Slightly louder than stock but it does get louder at higher RPM. Very minimal drone at higher RPM. It’s very mature sounding yet loud enough to still have that iconic STI boxer rumble. It also does not have that nasty sounding crackle and pop. Thank God.

I’m really happy with my Invidia q300. You can tell it’s a very high quality exhaust and I’m satisfied with the results! It’s not a crazy difference from stock but has a nice, low and aggressive rumble to it. You can hardly tell it’s an aftermarket exhaust when the car is in idle, but as soon as I got it in the road and opened it up...it put a huge smile on my face. I just wish it was a big louder. I went with the q300 because I didn’t want any drone or something too obnoxious...but this is just a tad underwhelming. If you want a little more, get the r400 (if it’s in stock)! Nonetheless, I am very happy with my purchase! I absolutely love the look of the titanium burnt tips and it really gives the rear end that little something it was missing! Awesome.

I was looking for something not too loud for my 19 wrx. This checks all the box’s, performance and still quite. If you have a down pipe it wakes up a little more but not obnoxious. If you are looking for a louder sound, keep searching, the stock exhaust is louder than this one. It for me it’s perfect!

Bought this exhaust and installed on my otherwise stock 17 WRX (FA20). Build quality is exceptional, tips look the perfect size and I love the burnt effects. Install was very straight forward with the GrimSpeed adapter. I had one gasket left over, not sure why, hopefully I didn't do anything wrong. There were 2 small adapters (axleback sections), one medium, and one large. The large was the 3" diameter, so I put it between the two midpipe sections. The medium seemed too restrictive for 3" piping, so I didn't use it, and used only the grimspeed gasket for the downpipe to catback joint.

Sounds much deeper than stock from idle to 3000 rpm. Not necessarily louder, but deeper. At 3000 rpm it starts to wake up, then from 4000 to 6000 sounds great. Not roaring loud, but definitely louder than stock. I can still hear the turbo spool, and it sounds like the turbo noise and exhaust noise are in perfect equilibrium. I initially had a nameless axleback with 4" mufflers and loved the high rpm screams it gave off and the pops and crackles at idle, but had drone at 2500 to 3200 rpm that I couldn't live with. I guess you can't have it all and to me this exhaust is the perfect balance of definitely noticeable but not too loud for highway driving.
