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 beautiful 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.

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 10 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.

Quality product and service!
WVjones 1 year ago
I got my invidia n1 really quick from rally sport direct. It took me under 2 hours to remove the old SPT exhaust and install the n1. It could've been done quicker but the old exhaust had some very old nuts and bolts that were a pain! Only downside I have to this exhaust is that I wish it were a little louder. Its barely louder than my previous exhaust which is the exhaust that was on my car when I bought it (I believe mine was a factory upgrade exhaust, but not sure). The n1 is still sexy though and it has a good sound!

    Just wanted to make sure that I purchase all necessary gaskets in order for proper installation. Car is a stock 2014 Subaru Impreza WRX. Subaru OEM Donut Gasket (part # 44022AA123) x1, GS Universal Exhaust Gasket (part # GRM 020031) x2, and Remflex Exhaust Gasket (part # RF8006) x2. Can you please confirm?

    • A: The only parts needed for this install are 44022AA123 X1 and GRM 077046 X1.

  • Q: Pipe size   Mr_subaru06 3 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.
