Premium Exhaust, great for everyday
Purchased and installed Q300 recently. Fit and finish is high quality. Sound at idle is not much different then stock, maybe 15% louder. Sounds good when on the throttle, but not obnoxious. I am older and not looking for attention from "Officer Friendly" or anyone really. Great for everyday use. Looks fantastic on the car. I plan to keep my vehicle for a long time, I have no doubt this exhaust will be able to stand the test of time. Also the sale price was unbeatable for the quality you get. Great job Subiespeed and Invidia!
High Quality & Quiet
Just installed the Q300 on my 17 WRX and could not be happier. I am older now and didn't want a lot of unnecessary noise driving to work and these are spot on! Barely louder than stock with a distinct low rumble and can't even hear in the cab wit the radio on unit you get into the throttle, exactly what I was looking for. Install was straight forward and components are very high quality. I spent the $30 for the install kit to go on the stock downpipe and glad I did.
Great Cat-Back Exhaust System!
Very happy with my new cat back system. Product quality is superb, and fitment is dead on! Exhaust sound is more than tolerable. I highly recommend this product.
I ordered the Invidia Q300 to replace my stock catback that bolted up to my stock downpipe. This kit came with everything needed. The toughest part of the install was getting the rubber hangers back on. I did this install bymyself, though it would have been easier with another person. The quality of the system is superb and the sound is even better. Its about as loud as stock at idle with a lower rumble. Once you get into the throttle at higher RPM's the sound becomes more disinct, but still not annoyingly loud. (Tip:) Once pre-assembled and installed, if your tips are not straight where you want them, try loosening up the bolts and nuts at the joints and let the mufflers settle or be persuaded into position. Then just retighten the bolts and nuts. Great buy! I would defin. recomend for those that want a racy tone exhaust without the loud droning or "wrong time" attention grabber. (Cops
2015 STi Invidia Q300 A good choice for a fair price
I recently purchased the Invidia Q300 cat back exhaust for my 15 STi. After many many hours of sound clips and reviews I decided to pull the trigger on the Q300. I am very happy with my choice. It was easy to install. I did it by myself in my garage with minimal trouble in less than an hour. The quality is very good from what I can tell. The fit was good I have no rattles or exhaust leaks and the bumper clearence is just right. I re used the stock exhaust hangars and didn’t have to order any special gaskets to get a good seal on the stock downpipe. The only advice I will give is if you are planning on hooking up to the stock downpipe the Invidia hardware is too big for the factory downpipe flange, they won’t fit through. I had to get 2 - 2” x 5/16 bolts at the local hardware store in order to complete the install. I am assuming Invidia probably expects you to be running an aftermarket downpipe.
As for sound, it is a noticeably deep rumble over stock, it is not obnoxious and the drone is minimal. This exhaust gives you the sound you want from a car like this but can be quiet enough if you don’t want to attract any unwanted attention.
quick delivery,easy install
Fitment on 2015 wrx is acceptable, not perfect. No clearance issues,
slight mis-alignment of tips. Only slighty louder than stock.
