Invidia N1 Dual Cat Back Exhaust / 5STIGTX-PARENT Fits
14 customer reviews
Exhaust shipped fast and went on with ease, a good humble sound on the FA that gives off a sporty note and no scratches in the high rpm. Worth every penny.
Good All Around
I was very pleased with this exhaust. It's not super loud and doesn't drone on the highway, but still has a great exhaust note. I ran with this for three years before changing things up and never had a problem.
Great Quality & Sound, SUUUUUPER HAPPY
Ok, I read a lot of reviews and watched a lot of videos on this exhaust before I bought this thing along with scrolling through forums. I tried to look up a comparison of this exhaust (Dual N1) compared to the R400 Exhaust, I couldn't find anything. Let's start off with the installation, it was pretty easy once you get the stock OEM parts off the car. The hangers sucked to get off bad, recommend using some silicone spray to loosen them up. I bought the GrimmSpeed Donut and OEM downpipe to 3" exhaust gasket worked out great. Overall Installation was easy if you are able to jack up the car high enough to create some space! Sound: This thing sounds sick, the videos on youtube don't do justice really. It's not loud at idle (which is not bad) it's loud when you get on it and rip through gears, it has a nice feel in the backend of the car so it actually feels nice to drive. The stock exhaust didn't really feel like it had much going on maybe a hint of sound but this thing you can feel on your ass int he seats... As far as Performance: Everyone says this thing won't give you performance gains without replacing the downpipe, I kept my stock exhaust and I can feel a difference. My peak boost before replacing the exhaust was about 18.3 , after swapping the cat back I am now bossing at 22.6, the feel is more powerful and hearty when pressure is built up. I feel like the overall driving experience from OEM to this Performance Exhaust was what I needed to feel complete. I wanted to get into the stage 1 and 2 deal with the car but I don't wanna rely on e-tunes or paying a bunch for a dyno so I think overall replacing the catback , and swapping my shifter to a short throw (the rest of the car is stock) the car feels great. SUUUPER HAPPY
Best Sounding exhaust for the FA motors!
I got the normal shipping and the box was at my door the next day. I also ordered the Indivia catless J pipe. The exhaust brings out the Subaru rumble in the FA motor that some didn't know was still there. The exhaust went on smoothly. I'm glad I went with this exhaust over any other.
I could not be anymore more happy with my purchase. This exhaust is the perfect building block to my STI. I am very excited to continue to use Invidia products has my next purchase will be their catless downpipe.
Must have exhaust
This exhaust is a beast! I was more then thrilled on how easy the install was, just a few bolts and hangers. The quality of the welds was also very impressive considering I'm a welder as well. The sound will put a huge grin on your face. A greta tone and doesn't drone when going highway speeds. Great performance as well I definitely recommend this exhaust.
Nice deep sound, the exact tone I was looking for. Loud but not obnoxious, so I opted to keep the provided silencers out. Installing was very straightforward, however removing the old exhaust was a little troublesome. No issues with the fit and was an easy/direct install. A+
Installed this to my 2015 wrx. The installation was pretty easy, everything fits perfectly. Took me about an hour to finish the job. The sound is pretty nice, it has that deep mellow sound. I highly recommend this product. Thanks subispeed for the great customer service.
Good quality, Fast shipping
The difference between this exhaust and the stock is night and day. Much throatier than the stock and not too loud to where you're worried about pissing anybody off. Included in this package were the silencers which i was stoked to find out. Easy to install, great quality and Subispeed was quick to ship as always.
Perfect exhaust for the Subie
The exhaust is amazing. Not as loud as I thought it was going to be but it definitely makes a difference. The exhaust fits perfect on the car. I bought the grim speed adapter and Perrin hangers. When adjusting the exhaust I found it best to put the entire exhaust up and work your way from the back of the car to the front where the cat is. I am not giving it a perfect rating because my box was severely damaged as well as my exhaust tip on the driver side.
Amazing Product and Fast Shipping
Installation only took about an hour. Everything fit perfectly. This exhaust is a piece of art and it is even better when you get to hear it! I strongly recommend this product for anyone in the market for a cat back exhaust. Look no where else. Thank you Subispeed!
even a bit of burbull
Installed this on the 15 wrx. It fit perfect to the turbo back j pipe from Cobb and the tone is even nicer then what you hear on the video with the turbo back. A bit of drone far less then stock. It's loud..... quiet if you hold in 4 5 or 6. Any Excell and it's there all around you. The kind you will love.
Good Quality Good Sound
This is my first system from invidia and I can say that it wont be the last. Its hard to find any flaws with this exhaust system. Without the silencers its about 3-4x as loud as stock but its not obnoxious. Went straight in in less than a half hour and it fits nice and tight. Much respect to invidia.
Great Product/Fast Shipping
This is a very mellow deep sounding exhaust. No drone and smooth sound all the way through the rpm range. The quality is great as to be expected. Easy install about and hour everything meets up perfect. From 1-10 vs stock exhaust loudness i would give it a 4-5 over stock. Oh and great service from Subispeed as always keep up the great work.
