Didnt have any issues installing this. Used Grimm speed adaptor. Everything went on exceptionally well. The right muffler pipe had slight bend but managed it.

Absolutely amazing exhaust, loud, low rumble, and beautifully designed. REMEMBER TO BUY A DONUT GASKET AND THE OEM TO 3” ADAPTER TO INSTALL THIS. It comes with everything but the adapter

Great no drone exhaust

This exhaust is perfect if u want something thats gonna have some nice sound but also be able to have a conversation riding down the highway at 70. There is no drone at speeds. The sound is awesome and has a nice 3rd gear crackle to it. A very easy install. With a lift i was finished with it in 45mins. Overall 100 percent recommend it. My son dropped the camera in the video but thats how it sounds on my wifes 2020 wrx

Jonathan,

Thank you for sharing your experience with the Invidia Gemini R400 exhaust for the WRX/STI. This is a great exhaust that provides sound and performance and that it does not produce any drone at highway speeds. It also looks incredible! As you said, installation is straight forward and easy, a lift definitely helps! Thank you for your 5 Star Review and added video!

Regards,

Great sound

It’s not to loud, also has a great low sound to it

Joseph,

Thank you for the 5 Star Review! The Invidia Gemini R400 SS Quad Tip Exhaust is an aggressive looking exhaust that has an awesome tone that provides more HP and torque! Enjoy!

Not bad but for the money i would....

Got this and installed it, pretty simple. First not all hardware needed is included. You need to buy the adapter kit, 21 WRX, extra $. :-( , i also have an issue with one side of the exhaust sags, and have read on the forums that others have had same issue. Not very much room to adjust it. :-( , sound wise, its ok, a little too much droning. looks good, build quality is good. over all 7 out of 10. given the choice, i would not buy again.

Patrick,

Thank you for your feedback. We are glad the Invidia R400 Exhaust looked and sounded good overall, but we’re sorry to hear about the missing hardware, sagging fitment, and drone. Your notes are valuable for us and the community. 🙏
