Invidia Q300 catback

Posted by Chavez on May 16th 2023

Really like this exhaust, has a nice rich deep tone that is sporty but doesn't drone at highway speeds. I went on a 4 hour round trip road trip and didn't hear it really at all. Will probably run with boost on my Civic SI when time comes.

Q300 invidia catback

Definitely brings the car to life, if you dont want crazy loud but want to hear the vtec better inside this is the best exhaust. subtle from the back good sound in the interior and very little to no drone.

great exhaust, great sound

Posted by Lukas Woods on Aug 10th 2018

This looks great, arrived on time, and sounds awesome. It doesnt drone at highways speeds below 70mph so thats great. The inside was dirty when it arrived but that wouldnt both most people. I cleaned it out with a large pipe cleaner before the installation. The welds look great. I have noticed the tip gets dirty fast but cleans up easy with a quality wheel cleaning product. The nuts and bolts provided are cheap so I'd buy your own. I snapped/sheared two in half and it was barely getting tight. Overall I'm very happy with the product and hardmotion did a great job too.

Love my q300, these guys always have them in stock or you can even pre-order from them when the manufacturer is making its next batch. Got mine right away. Love the sound, best exhaust out. Great fitment, super good pricing.

Awesome Exhaust

Posted by lamar on Apr 19th 2018

Q300 exhaust is one of my favorite exhausts, had it on my 8th and when I got my 9th gen I came right back to hardmotion for another. They always have these in stock when other shops dont! Great sound yet again, amazing fitment, beautiful build quality!

These guys rock!

I emailed my questions about what exhaust they reccomend for a mature / easy going exhaust note that offers a good sound under hard acceleration. They immeidatly told me about this exhaust. Ordered it up, installed it in literally 45 minutes. Welds are amazing, fitment perfect, the sound is exactly what I wanted....nice sporty sound under regular driving, just so smooth and under hard acceleration a throaty tough sound! I was worried about my honda sounding bad....but this exhaust is perfect! price was insanely good too! Thank you!!!!!
