Rsx invidia q300
Mountaina | January 5th, 2021
Nice deep sporty tone on outside, when inside the car it sounds louder from my engine and the exhaust kinda drones but maybe because I have the trunk all gutted so probably have none of that trunk interior stuff to help keep the road noises out. I did have plm head installed with it. The plm header gave fitment issues, so I got the plm test pipe cut on both ends and flipped the pipe and reweld. Onto the axle back part, if you hear a knock on the back of your car, chances are that the axle back is hitting the frame of car, the axle back has 2 hangers and one hanger you can see it literally leaning against the car frame. So I took coolant hose, cut small piece to wrap around the hanger which makes contact with the frame. Worked out good and zip ties so it won
Too much Drone. Definitely not quiet or close to stock

Giving this 2 stars because although the workmanship on the welds are nice and the included hardware and gaskets are good; there were fitment issues and was not quiet as advertised. The midpipe does not fit well and hits the floor of the chassis. My mechanic had to pinch the part of the pipe that hit the floor. Really shouldn't expect that on a $600 catback. Once we got everything installed the noise was unbearable. I previously had a Raceheader with the ExMag RSR exhaust and was loud enough to sound great but didn't have drone. The Q300 was louder with a shorty header and a test pipe. Idle was quiet like stock but anything above 60MPH even when cruising was drone. The sound resonated in the cabin which got annoying quick. That may be fine if that's what you want but Invidia and the forums advertise this as if it's close to stock, which is far from the case. Besides complaining about the noise, the sound is not ricey. Its a very deep growl tone and sounds like a banshee when in Vtec. I ended up selling just the muffler and reinstalled the stock muffler. Screams when in vtec but quiet as a mouse when you just want to cruise.

Shout out kseriesparts for always being the best plug for my rsx-s. The exhaust is beautiful. Invidia has done some quality work on this. My initial thoughts were wow this is bigger than I thought. The muffler is huge, bigger than stock I think. The test pipe and resonator are A1 quality. Comes with all the hardware (bolts/gaskets). Now for the sound; I'm gonna be honest, it's a lot quieter and less aggressive than I expected so I was a little disappointed. I wanted a quiet exhaust bc I hate people who have loud exhausts but their car is slow af. Didn't want to attract unwanted attention from cops and ricers. I knew this was going to be a quiet exhaust but not stock quiet. It literally sounds just like stock but noticeably a little louder and way more bass. Low tone rumble. And when you hit VTEC, it doesn't scream as loud as others have said. The only other mod I have is injen sri and I can hear that more during VTEC. Now don't be discouraged bc I am inside the cabin so I don't know how loud it is outside. Inside the cabin there is no drone at all but you can hear the low tone bass rumble of the exhaust. At idle on a red light, you can barely hear it. The common problem of the muffler hanger hitting the body of the car is still alive and real. When you hit a big bump on the road it will bang against the body. I fixed this by wrapping a hose around the hanger so it acts as a bumper for it. So I am hoping when I buy a header it'll be a little louder. My final thoughts are: yes it is a great exhaust. I gave it 4 stars because it's over priced for sounding similar to stock but just more bass and obviously a little louder. HP gains? Maybe idk I can't tell but I can feel the car flows better. Can't really tell until I get a header and tune. So if you want a quiet exhaust that's a little louder and deeper tone than stock this is the one.
