Description

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 less restrictions. This means you will have improvements in throttle response, along with increases in both horsepower and torque. 

This exhaust will come with premium mufflers and a set of beautiful quad polished tips, and the exhaust hangers are welded onto the stock location of the pipes so you don't have to perform further modifications.

New gaskets and hardware will be included to make this exhaust system ready for installation.


This exhaust is for the 2011+ WRX/STI sedans ONLY. Will not fit the hatchback models.

Q300 on 2012 WRX
Kamran 1 year ago
Fits perfectly and sounds great. I got it installed at a local shop took them roughly 45 min to an hour. Not too loud or obnoxious it has the perfect pur! The shipment was very fast I was definitely not disappointed! I could't decide between Cobb catback or Q300 catback and I'm really happy with my decision.

Aggressive boxer sound when you floor it, same sound as stock when cruising. Perfect combination. Great look, easy to install. Currently installed with cobb intake and cobb downpipe.

Some things you should know before buying...
Hawkeye 2 years ago
Nicely built exhaust system, but the only thing people ever talk about is "drone." No one has talked about other issues with this exhaust that buyers should be aware of. Such as the fact that this Q300 system is lacking drone because it's more restrictive than other exhausts, like COBB for example, that are much more free flowing. This restriction in the muffler design causes great low end torque gains (on stage 2+ tunes) but really causes the power band to fall flat and plateau at around 5,000-7,000 RPM so there's very little top end performance. Additionally, this exhaust system is NOT very loud. It's just a little louder than stock. So for people looking for a loud and "in-your-face"exhaust, this is not the one you would want to buy. Hope this helps future buyers make the right decision.

  • Q: Difference   midnightprince304419 2 years ago

    Answer

    2 part question. #1 What is the difference between this one a day the titanium one? Is there any power, weight, or sound difference? And #2 what's the difference power wise between this and the dual exhaust?


    • A: The only difference is the titanium tip version has a blue finish on the tips of the exhaust. The system is still constructed from stainless steel. Pretty much all catbacks will offer near identical power gains.
