This is Invidia's newest addition to the 2015+ WRX / STI exhaust lineup. They already produce some of the most popular exhaust systems for the WRX / STI. Their designs result in an excellent free-flow exhaust system with optimized back pressure, giving greater horsepower, torque gains and a rich deep sporty sound. The use of SUS304 polished stainless steel piping, mandrel bent to shape, state of the art CNC machine made flange, robot TIG welding and single wall polished stainless steel or titanium tips, provides outstanding durability and appearance.

If the N1 and Q300 systems weren't quite exactly what you were looking for, take a look at this.

  1. LOVE IT

    By OZZY July 4, 2019

    Easy installation, fitment was great. brought my STI to love love the sound and shipping speed was surprisingly fast. only slight difficulty was getting the exhaust to line up center but nothing too dificult. Most definitely recommend this product.

  2. Great sound, brings out rumble. Quality control? not so much...

    By Anthony June 22, 2019

    Let me start by saying this, the R400 is a perfect exhaust for somebody that wants that deep rumble, not terribly loud, but just enough to give you a good smile when going through a tunnel or rev-match downshifting. However, my exhaust arrived with the box pretty damaged, the mid pipe flange was hanging out of a hole in the box. I wish quality control on these exhausts were a little better. The welds are next to terrible, and no matter the hanger, zip ties, or man-handling, I could not get this exhaust to sit where I wanted, evenly spaced and sitting flush with the bumper. It got to the point where it had burnt some of the plastic on my bumper unfortunately. Maybe this is just one in a million from them, i've had multiple invidia exhausts for different cars, always loved them and their quality, just wish it stayed consistent... I am happy overall, just wish QC was a little better.

  3. Wake your Subie up

    By Erick November 16, 2018

    This upgrade not only is super easy to install but also looks and sounds amazing!!! You can totally tell the quality in which is made from a mile away. I was able to install it by myself in my garage with jack and jack stands. The deep rumble brings a big o’l smile to my face. This must be the most beautiful sounding exhaust I’ve owned. The box came broken but didn’t notice nothing missing, Quick delivery though . I did miss seeing the laffy taffy Subispeed.

    I have a 2018 WRX STI Type RA. And just installed the exhaust. It took longer jacking the car off the ground then the installation. I used the adapter which really assures a great seal. The revs are a bit snappier along with a bit more torque and a slight rasp which is cool. I have the stock down pipe and you can hear a slight turbo spool now. No drone sound to talk about. The cabin noise is a tad load but it drowns out the tire growl on the highway. lol Its definitely a nice quality piece. When you're in the pedal the car can be heard from blocks away and no need to beep the horn at those suspecting lane changers you might come across. I would definitely recommend this pipe.Once car was on stands it took all of 30 minutes to remove and install new pipe.

  5. Wrong Attach flange

    By Tom July 31, 2018

    The Exhaust installation was so easy on this system until it came to the attachment to the Cat Flange. On my 2018 STI, the flange that is on the CAT pipe is a conical where the flange on the exhaust is a flat. All Invidia needs to do is make this a conicle flange and it will fit both flat and conicle CAT pipes.

  6. Best Exhaust For The Price

    By Stephen May 5, 2018

    Installed SS tips on my stock 2017 WRX. Great rumble on cold start, pops on up shifts, and no drone cruising at highway speeds. Install is easy (1-2 hours), just have to play with tips to get them perfectly centered. SS tips look awesome definitely worth the wait and extra money.

  7. Clean fit, looks good

    By Ranzumze February 28, 2018

    Before install, checked with My Subaru dealer to make sure it was not going to void the warranty. They not only allowed this on a car with a full warranty, they even installed it for me. Has a deeper tone to it up through the gears, but not much louder than stock when at an idle. Much cleaner than the OEM exhaust, seems to breathe better, stainless steel will keep it in shape much longer, totally bolt on, very clean install

  8. Worth the wait

    By Mike August 6, 2017

    Ordered the SS tips when they where on back order knowing I would have to wait, thought it would be months but with in 20 days my order shipped. Installed was pretty easy, only issue was with figuring out the grim speed stock dp to cat back adapter. Quality is amazing and welds are clean, once you start your car it really comes to life compare to stock. Can't wait to add a dp to really open up the exhaust more.


    By MAU. STI May 4, 2017

    Overall easy install, had to play a bit with it so the tips were centered but nothing crazy... Once you start the engine HOLLY [email protected]#& this thing is crazy you will fall in love with your car once again... Totally recommend this product
