Invidia Q300 Exhaust | 23+ Integra Type S DE5

Absolutely love the product - its loud without being obnoxious, it has plenty of volume and depth without being boomy and droney.
The box/packing materials are very poor, as expected from Invidia - but it arrived undamaged overall.
Installation was done on a lift which makes it immensely easier so I cant really comment on difficulty of install.
Got many positive comments recently about the sound and looks.

Sounds great. Nice deep tone. Pops sounds amazing. Little to no drone.

Very happy with the supplier. Good communication and fast shipping

I'm so happy I found this exhaust. It has the bangs and pops you want in sport + mode and is quiet in comfort mode. Highly recommend to anyone looking for a new exhaust. Big Thanks to Humaz, Junayd and everyone in Unity Performance.

I also wanted to live with the Invidia Q300 on my 2024 DE5 prior to review. I've had it installed for several months now and while I am impressed with the quality of the parts, I must say I am very unhappy with the booming sound in the cabin at all settings (comfort, sport, or sport+) and at lower rpms (2,000 to 3,000 rpm), part throttle and under load.. Unfortunately this rpm range corresponds to highway speeds. If I am in 6th gear at 65-70 mph, and under part throttle with some load, the booming sound is very unpleasant. It sounds like a truck with a bad muffler to be honest. I've found myself selecting 5th gear to raise the rpms a bit which does alleviate the issue.

The worst situation for me is the booming sound at comfort setting since I wanted this exhaust to be quiet when desired.

I've written to Invidia asking for a suggestion for an alternate (quieter) resonator but have not yet heard back.

On a subjective note, I find that I prefer the contrast of the stock polished exhaust tips with the black diffuser. The Invidia burnt tips look great up close, but from behind the car they disappear into the blackness. I do like the exhaust sound when under heavier acceleration and higher rpms but this only happens occasionally. Normal driving for me tends to be in the 2,000-3,000 rpm range.

So overall a mixed bad with the Q300 on the DE5 for me.
