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 3" 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 premium mufflers and a set of beautiful 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.



Note-
Kartboy standard exhaust hangers will not work with this exhaust.

Great Looking and Sounding Exhaust 6 months ago
5out of 5stars

I originally got the R400 exhaust and that was way too loud for me. I sold that one and gave this is a try. This exhaust is loud enough to hear a nice growl, but won’t annoy you during your daily commute. Both Invidia exhaust fill up the exhaust outlet in the back very well and look amazing. My younger self would have stuck with the R400, but now being in my 30s this is the perfect exhaust for me. My exhaust was missing some install hardware, but rallysport customer service is always great and Invidia was very responsive as well.

Great exhaust, very happy  1 year ago
5out of 5stars

I got the q300 after a year with a nameless muffler delete and catless downpipe. My Wrx was really loud and I had gotten pulled over by police just for that. I decided to go with the q300. It’s perfect, it’s quiet when you want it to be and loud when you get on it . I imagine it’s pretty quiet with a stock down pipe but with an aftermarket dp it sounds awesome! It has a deep rumble to it and it looks amazing with my blue tips. Overall very happy and i feel like it increased my Performace though I’m not sure

Sweet exhaust  1 year ago
4out of 5stars

After a year with a cat less downpipe and nameless muffler deletes and getting over twice for my “modified exhaust” I decided to go with the q300 because it seemed like the quietest one. It sounds good with the cat less invidia catless down pile as a good rumble to it. Still pops, and it looks sweet with the blue tips with my WRB. 8/10

QUESTIONS & ANSWERS

  • Q: Nameless Downpipe to Invidia q300  SLW16STi3 days ago

    Will I need an adapter to mate the nameless downpipe to the invidia CBE or will I just need the donut gasket that is already supplied on the Downpipe?
    • 0 of 0 people found the following answer helpful

      A:  It is recommended to use an adapter to mate this to the nameless Downpipe. The Nameless Downpipe is meant to mate directly to a stock Midpipe.
