If you are looking for a great way to squeeze a little extra performance from your vehicle, then you will be pleased with the Invidia Q300 Cat-Back Exhaust System. There are several performance attributes that makes this an excellent upgrade. This exhaust system has been made from 304 stainless steel and features 76mm piping. The exhaust has also been designed with minimal bends to reduce the amount of turbulence during acceleration, allowing the engine to exhale the exhaust gasses with fewer restrictions. This means you will have improvements in throttle response, along with increases in both horsepower and torque.
This is a single exit exhaust system featuring a premium Q300 muffler and a titanium tip. Exhaust hangers are welded onto the stock locations which means you don't have to perform further modifications to the body or chassis for fitment.
New gaskets and hardware will be included to make this exhaust system ready for installation.

This is the second time (first time on a 2014 STI now on a 2017 STI) I have bought this exhaust with the grimspeed 3in adapter and 2 of the drop bushings. The exhaust is great. Loud especially with the windows down and does not drone on the highway, but depending on your speed can be loud. That is solved with the silencer but I have noticed that it will rattle at idle.

Exhaust came in with in a week of ordering it. Packaging was good and everything was spot on. Installation was fairly easy and took within an hour to do. The hardest part is removing the stock exhaust. This N1 race is noticeably loud, almost too loud at times. Nevertheless this exhaust is amazing and sounds great. Whenever you down shift you always get those pops which makes driving more enjoyable. Would highly recommend this to someone who wants a loud exhaust
Great sound... Duh

I've always been impressed with Invidia and their products. This is my second purchase from Invidia. I plan on also purchasing their straight J-pipe to compliment an affordable full exhaust bolt on. Fitment is good and installation is easy, even with only a jack or drive up lifts.
What i was looking for
SUBI DREW 2 years ago
I am very pleased with this catback. It was not hard to install. I did it by myself with minimal space to work. Uninstalling the factory exhaust is harder than installing the new one. The sound is great it adds a lot of bass to the car with virtually no drone.

Q: 2017 STi Fitment ThatSTiGuy 4 months agoAnswer
I have a stock 2017 STi, and I purchased this exhaust second hand, but it didn't come with gaskets or the adapter. Could you reference the part numbers of what gaskets and adapter I'll need ( if needed) to fit this up correctly? I figured it would be something like 2x 3 inch gaskets, 1x 2.5 inch gasket, and the adapter?
A: That is correct, you would need (2) 3" gaskets, (1) 2.5" gasket and the Stock Downpipe to 3" Catback Adapter.
