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 exhaust will come with quad titanium 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.

Great sound and easy install with the Grimmspeed adapter
Nbarley12 1 month ago
Amazing exhaust, looks very good from the rear of the car and has a nice burble. The titanium tips are a great option that really make the rear of your car pop. Ordered through Vex Performance out of Calgary, AB who ordered for me from RSD. Easy install if you have an extra hand around. Drone is very minimal and completely gone at highway cruising speeds. Has the occasional pop and bang at 3,000-3,500rpm when you let off the gas :).

Insane drone
jermismo 4 months ago
The exhaust sounds great outside the car, but between 1800 and 2500 RPM it drones like crazy (2011 WRX Hatch). Makes your ears feel like they need to pop. It wasn't that bad when I first installed it, but it seems to have gotten worse over time. I've probably had it on for about 1000 miles. Sound deadening didn't help.

Boxer Rumble!

Build quality is excellent! I have it paired with a GrimSpeed DG DP and stage 2 map from Cobb. Power gains are very good! I felt a more precise turbo spool and much better top end power. The sound is just what I was looking for, very deep rumble and not to loud and nice note at idle. If you have the little extra cash get the titanium tip option it looks super cool and very tasteful. Overall very satisfied with the purchase, and thanks to Rallysport for the super fast shipping! Got it in one day!

I owned this exhaust for almost 5 years now and i must say i really like it. I have it paired with invidia catless dp, all in all its not that loud inside the cabin but if your behind its pretty loud and it actually looks like stock from behind.

Great product and customer service

I ordered thru the phone and Michelle recommended me buying grimspeed adapter for easier install. I installed it myself and took me about an hour and 15mins, hardest part was taking the OEM hangers on and off. The box was a little banged up, probably because it was shipped twice(original shipping method was a bust) Anyway, this product is awesome! Best bang for your buck, specially the Ti-Tip. It makes my rear pop! :) Grimspeed adapter came with a gasket so I had an extra gasket from the invidia. Last picture were my dogs waiting on UPS to deliver the catback.


  • Q: Downpipe Compatibility  AndrewK 6 months ago


    Hey guys, I've got a hyperflow downpipe ( currently on my 2012 wrx hatch. Just wanting to know if the Q300 is compatible?

    • A: This will work with most downpipes but its best to talk to the manufacture of the downpipe to ensure it fits.

  • Q: Cobb downpipe   Abbwrx 7 months ago


    I purchased this payback recently and I'm interested in purchasing the cobb downpipe eventually after I get an accessport, I understand the that cobb piping size for the downpipe is 2.5 inches while invidia midpipe is 3, are there adapters of any sort to make them compatible or will it have to be cut and welded together?

    • A: To get the best seal with the Cobb downpipe, an OEM downpipe to 3 inch catback adapter would be recommended like INV HS02SWIAPE or GRM 077046.

  • Q: Compatability with 07 legacy 2.0R  Legacy07 1 year ago


    Title pretty much says it all, will this work with an 07 Naturally Aspirated DOHC Legacy? Thanks

    • A: This is not a direct fit for your legacy, major modification would be required to make it work.

  • Q: midpipe  itsjeffree 2 years ago


    does the q300 and n1 dual have the same midpipe?

    • A: Yes they will have the same mid pipe as they are both routed the same way underneath the car.

  • Q: Silencer  TiE10 2 years ago


    I see you guys offer some silencers. I bought this exhaust a while back and love it but want to put a silencer occasionally; do you know which one would work best with this? Also, are there any assemblies available like in the Varex system using a solenoid/actuator controlled flap to close off a couple some of the tips on demand (of course would require custom modification to the exhaust)?

    • A: Invidia does not produce a silencer for Q300 exhausts at this time. Invidia doesn't have an adjustable baffling system currently. You may be able to fabricate such a system, but that would be a custom job.
