Features & Product Details

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.

I'm overall very happy with this exhaust. When I was in the selection process drone and noisy raspy crap cannons we're on the top of the do not want list. It has just the right amount of boxer burble with a stock downpipe and is hardly noticable in the cabin going 60. The tips look great too gives the rear just a little more of a filled out look.

Great exhaust 12 months ago
Bry954rr
Sounds really good. Not too loud and has the great rumble yr looking for. Sounds like a stock exhaust until you get on it. I have tried the nameless muffler delete and hated it. It was too damn loud and sold it after several days of using it. I was thinking about getting the dual N1 for my 2014 wrx sedan but i didnt want the same experience as the nameless muffler deletes. Forums say the the N1 was just as loud as the nameless muffler deletes so i passed on them. Spend the extra $200 on getting this exhaust over the N1. You will not regret it. Perfect exhaust if yr not going for the obnoxiously loud route. It does not attract unwanted attention unless u want it to. If yr reading this review, just get it already.

Q300 on 2012 WRX 3 years 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.

QUESTIONS & ANSWERS

  • Q: Adapter & Improved gaskets  Vaughn4 months ago

    Do you sell a set of higher quality gaskets than this comes with? Mine seems to have gotten crispy and rusty over the last few years. Also I noticed the first pipe doesn't make a very good connection to the factory pipe. Is there an adapter of sorts that allows this to mate perfectly to the factory exhaust?
    • 0 of 0 people found the following answer helpful

      A:  The recommended replacement gasket part numbers are below. GRM 022001 Or RMF RF8006 GRM 020031 You will need two of each gasket if you want to replace all of them. The fitment issue is due to the size difference, we would recommend GRM 077046 and OEM donut gasket.

  • Q: 2012 Subaru WRX STI Sedan  STIKX4 months ago

    I'm so new to this. My car is currently all stock. Will this be a direct fit? Or would I need a Downpipe, or adapters to connect it to the stock pipes? I highly appreciate your response.
  • Q: Fitment  cmwilliams4002163386 months ago

  • Q: Difference   midnightprince3044193 years ago

    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?
    • 0 of 0 people found the following answer helpful

      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.
