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 N1 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 a beautiful pair of titanium tips on premium mufflers, 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 come with this exhaust system to make it ready for the installation. 

Kartboy standard exhaust hangers will not work with this exhaust.

atleast one thousand percent sound improvement!!!
Steve Harris 17 days ago
I've got a 2015 WRX base and I love the car except the shifter, and the exhaust sound. So I got the Perrin shift stop, Perrin Brass bushings, and now shifting is great . Next thing on my list is the crappy stock exhaust sound, so I watched a ton of videos, and read on all these WRX forums, and decided on the Invidia N1 Cat back exhaust ( 3 reasons , won't void warranty, much louder, and also I wanted that Suburu rumble ). Now I didn't realize the FA 20 engine is equal length headers , so I'll never get that rumble I want, but this exhaust is vastly superior to stock!! I got it super fast, props to Ralley sport for that, and also there customer support , because looking on the forums I discovered if you don't get the Grimspeed adapter, and OEM donut adapter, you'll have an exhaust leak, I called Rally sport and they looked up the part numbers for these two items, and sent them out to me. I went to an exhaust shop and he charged me about $170 to put it on, and it sounds great , and the car even feels like it drives better .. now it wasn't that loud , after reading reviews , I was thinking man I hope I don't get pulled over for this because it's so loud. It's a lower sound , and much more aggressive , but not at all loud , or drone y, I wish I would of done this six months ago!!! so much better, if you want it loud though , you have to do a j-pipe ( which requires a tune) and it will never sound like an EJ engine , so don't be all disappointed!!! and the quality of it is top notch, when you see the stock ones off the car they look so cheap and crappy!

The box and packaging as I received it were in excellent condition. Very well wrapped and with cardboard covering the tips which also helped keep fingerprints off during install. This also was the least costly website to purchase this exhaust from. The hardest part of the install was removing the old exhaust actually, everything slid right into place and bolted up perfectly. It gives somewhat of a low rumble and sounds great at about 3k rpm and higher.

So after about 2 months of debating, I finally pulled the trigger and ordered for my 2015 WRX. Paid on a Tuesday, it was delivered on Friday, and install took less then an hour. I was really wanting to keep the quad tip look, but finally decided to order thinking I could add tips if I didn't like the look., Sound is great, look is great. Only complaint would be that it is not as loud as I thought it would be. If stock is like a 2 out of 10 then this would be like a 4 and that is at 6k shifts and 20 psi on the turbo

  • Q: Fitment and Additional parts?  pnoWRX 29 days ago


    Will this fit my 2017 WRX and are there any addition parts needed for installation??

    • A: Yes, this will work with a 2017 WRX but if using the factory downpipe, you will want an OEM downpipe to 3 inch catback adapter.

  • Q: Invidia N1 Cat Back performance gains?  Mr. Means 5 months ago


    I recently purchased this for my stock 2016 WRX. I wanted to know if this will give the car any performance gains without any other modifications. Will it improve HP or torque?

    • A: Invidia does not have any write-ups showing/proving their catbacks add power. Typically, they do not.
