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 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.

TJB1013 1 year ago
Exhaust arrived 2 days after ordering. Install was very easy, about 30 min. with all hardware included. Great fit and finish. Perfect sound! Not too loud and no highway drone if installed correctly.

Great Quality Sound

Great product from start to finish. Immaculate pipes and welds, all supplied bolts/gaskets and a beautiful sound. Was not positive on how loud it would be, nice Subaru sound at normal driving but let me assure you this is not a quiet system when on the throttle. You wont regret this purchase. Installed on 2011 STI

Great Exhaust!!

This exhaust looks and sounds great! Even after a tough South Dakota winter the Tips polished up very nicely and the muffler still has that nice mirror finish. Great product, would highly recommend to hatchback owners looking to get the full effect of the sound of a boxer engine. This one is not aggressively loud, it sounds great for a daily driver.

I am the type of person who rarely write reviews. However after the simple 1 hour installment and the amazing Subaru Boxer rumble that came out of those pipes, I felt like I had to write a review. I got the Cat-back exhaust and it sounds great. There isn't the drone-like sound at high speeds (around 65-80 mph) which is great because I do a lot of highway driving. It isn't EXTREMELY loud when driving through town. However it gives off a rumble during down shifts. But no matter what there should be no reason why anyone should be complaining on how loud the exhaust is because your getting exactly what you paid for which is the Subaru Boxer sound that you have been wanting from the beginning. I would totally recommend this exhaust if your just looking for a good bass like normal exhaust without attracting too much attention to yourself as well.

All around great

Super easy install less than 45 minutes, did not need to buy an adapter for my stock down pipe and I have 0 exhaust leaks! Not super loud so if loud is what you want don't buy this one. Has a nice deep rumble. 2013 Wrx pro tuned on 18 psi and cat back.

  • Q: Mating question  Evansr06 2 months ago

    Answer

    Does this exhaust mate up with an aftermarket Cobb catted DP on 2013 wrx?


    • A: This will pair up to the Cobb Down Pipe with this adapter and an OEM doughnut gasket https://www.rallysportdirect.com/fits/2007-subaru-impreza-wrx-sti-2-5/exhaust-gaskets-and-hardware/grm-077046-grimmspeed-oem-downpipe-to-3in-cat-back-adapter.

  • Q: Quiet But Throaty Exhausts   Snowhunter 2 months ago

    Answer

    I used to have an Integra with a DC Sport header and Greddy catback. I loved that sound - quiet idle and highway, but a deep throaty response under power with no tinny or buzz sounds. It sounds like this Q300 might give my overly quiet 2014 STI a similar sound. I like the sound of the 2016 STI, mine almost sounds like a base impreza. I would like something just a touch louder than the 2016 stock sound. Is the Q300 the best choice? Are there any other products that I should consider?


    • A: The Q300 will offer a deep sound quality but won't be as raspy as the N1 model because of the larger muffler. The Q300 is a great product for those who want to change up the sound to a deeper sound but still pretty responsive and plenty of sound.
