This exhaust fit for for 2018 wrx thank you?

Yes this will fit your 2018 WRX.

Hi is there an invidia exhaust with just the wide pipe and quad tips?

Unfortunately Invidia only offers catback exhaust systems for your 15-21 WRX/STI.

Will this cat back exhaust fit on my 2019 wrx limited with stock down pipe?

Yes it will. You will need the OEM downpipe to catback adapter.

Is there any downpipe to buy with this?

Yes we have plenty of options on our website. You will need to search for them as I cannot give you suggestions without knowing if you have a WRX or STI. If you need further assistance please reach out via email to support@subimods.com or call us at 860-291-0015.

Get mean!

The stock WRX exhaust has a decent sound, but the Invidia Gemini R400 Quad Tip exhaust is such an upgrade it almost feels criminal that it isn't the default exhaust. The R400 makes your WRX growl, accentuating the lower tones, while also filling out the engine's sound. The increase in volume helps you hear the engine more clearly, without being so loud it's annoying. I feel like that extra bit of insight I've gained from hearing the engine through the R400 has helped me refine the way I drive, particularly smoothness in lower gears. It's also very satisfying when you accelerate hard into higher RPMs, then get crackles and pops as the revs drop.

Trey,

Great

Love it just the sound I was looking for! Has a deeper tone and super easy to install

Recommend using some penetrating oil to help get loose some bolts

It’s a different sound!

I took off my nameless exhaust and put this on. I will say that my nameless exhaust was way louder. High-pitched loudness if that makes sense, this invidia r400 has a lower tone sounds way cleaner than the nameless that was on there. Super easy install I had penetrating oil for catalytic converter to takeoff the old one which helped a lot, but I highly recommend this!

Love it

Not super loud but has a very nice tone.

Ben,

The Invidia Gemini R400 Signature series is in the middle of the range for noise, but with that come more hp and torque! The Black Quad Tips look phenomenal and really stand out compared to other styles! Thank you for the 5 Stars!
