Invidia R400 Gemini Single Layer Quad Black Tip CatBack Exhaust Subaru WRX/STI 2015-2021 | HS15STIGM4SB

I heard sound clips of this exhaust and thought it was second to none so I pulled the trigger. I have zero regrets. Install was pretty straight forward and took about an hour. I was able to install this by myself using jack stands to hold up the rear. I am small so I was able to squeeze under the car where the j-pipe meets the catback. It was very uncomfortable but the job got done.

Gives my WRX the rumble it’s been waiting for! Easy to install and the shipping was CRAZY fast. Love everything y’all do!

Got this about a year ago, sounds great. Def a upgrade from stock. No regrets

I wasn't sure how easy this would be and as large as the exhaust tips are, I was not sure how they would fit in the cut out in the rear bumper cover. Its simply perfect.

Great fitment and quality

Sitting at idle can't even tell I have it on. Once you get into the gas it lets loose. Doesn't drone or get too loud at highway cruising speeds.

I’m sure it’s great but you asking me to review when I was told my order was full filled it wasn’t I haven’t got my full exhaust yet. That’s why I gave it this score don’t ask me until you given me it. I was informed it would take a certain amount of time and then it got pushed another month out toward end of jan probably in February. I was already disappointed that it got pushed to the end of dec, but to email and ask how it was when it hasn’t been done. Yeah sorry my dude, but like you said it is what it is. You don’t got me for another project. I decided not to spend the extra 5 6k for my stage 3 here anymore.

Best purchase I’ve made so far! The black tips look a million times better than chrome. Sound is awesome. Not too loud and not too quiet. Best price out of any places on the internet. Highly recommended

I am so happy with my purchase of this exhaust. It is a bit quieter than a muffler delete axleback with none of the drone and just all deep tone. I am glad I chose this over the Indivia N1 dual exit as keeping the quad tips just looks so much better!

Not too loud, not too quiet, mean but not annoying and it looks clean with the black tips.
