RallySport Direct is proud to carry the Invidia N1 Cat-Back Exhaust System. The N1 is among one of the most popular cat-back exhaust systems available as they make for an excellent upgrade over the OEM exhaust system to improve the performance and the sound. The combination of increased piping diameter along with smooth bends relieves the exhaust with restriction and turbulence under acceleration which will increase the horsepower, the torque, all while improving the throttle response and reducing the turbo lag.

Here are the key features:

  • Titanium exhaust tips
  • 101mm tip size
  • 304 stainless steel materials
  • 3" piping diameter
  • Silencers included
  • Exhaust hangers welded on to the OEM locations to allow for a direct fitment
  • New gaskets and hardware included making this exhaust system ready for the installation

Outstanding Product! Great Site!

I have always avoided the loud, ricey exhaust like the plague. This fine piece of equipment will give you that deep, mean boxer noise you want! Super easy installation. The quality of the product is amazing. The welds are perfect. After purchasing, I received the product 2 days later!!!! highly recommend this product & Site.

Exhaust installation was smooth once factory exhaust was removed. No directions are included, but installation is straightforward. be sure to double check which gaskets go to which connections.

The BEST $ spent on my car
Pat 12 months ago
I bought the n1 for my '13 WRX. The system is PERFECT. I have gotten endless compliments on the sound and looks of this thing. It really brings out the Subies VERY low toned rumble, does not sound whiney and ricey like the Hondas and Acuras out there with their straight pipes. Don't get me wrong, this thing is loud, But -- in the best way possible. It has the smallest drone on the highway when cruising at high RPMs but with the radio is barely noticeable, in a good way. When you open the throttle to pass someone you cant help but smile. The best part is, since its a catback, there's no voiding my certified pre-owned warranty. I do highly recommend you get the Grimspeed gasket to stop any leaks but other than that you don't need any other mods, it bolts right on easy and fits perfectly with the stock hangars. I had mine installed for an hour of labor at a Mavis Tire and when you step on the pedal for the first time and hear that low growl followed by a few even lower pops you'll fall in love. I don't know where to end, the quality is unmatched, packaged beautifully and delivered the next day just like my mudflaps, RSD is just CLUTCH, 5 stars all around. I know where to end this now-- BUY. THIS. EXHAUST.

Great sound, great performance. My WRX sounds meaner and deeper than most V8's I come across. Invidia makes an amazing product.

Rumble for DAYSS
_snowrex 1 year ago
This N1 is well worth the money. Invidia coming through with another great product of awesome looks and construction. The installation process took a little bit as a few of my stock exhaust bolts were rusted out and I ended up taking the exhaust off as one piece. Definitely lube up the exhaust hangers prior to attempting removal, you'll thank me. As far and installing the N1, it lined up perfectly with the stock cat, the hangers installed with ease, and the looks are spot on. The sound from this is a classic deep subie rumble. Decently loud but not obnoxious. A little bit of drone at highway speeds but if you don't like it crank the radio! Definitely would recommend to anyone wanting a quality piece at a low price.

  • Q: Pipe size   Mr_subaru06 5 months ago


    What size is this pipe? Looks like a 2 in. Just wondering , and also does it stay that same size all the way to the mufflers?

    • A: The piping is 76mm which is roughly 3 inches. The only sections of the piping that would change in size are the resonator, mufflers and the tips.
