Features & Product Details

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 polished 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.

Want that true Subie rumble? 2 years ago
PeytHott
I ordered the N1 along with the Invidia Catted Downpipe to upgrade from the SPT catback on my 2013 WRX. I was hesitant about ordering the N1 since many people complain about the highway drone. I put on 600 highway miles on a road trip the day after install and my only complaint is that I wish it was a little louder! The drone isn't bad at all and conversations and/or music can easily overpower it. The N1 sounds almost the exact same as my SPT at idle and is only slightly louder during non WOT driving. WOT is an amazing sound and brings out the classic Subie rumble. Great quality and fitment! Just wish it was a little louder at times...

'16 Forester XT with N1 exhaust 2 years ago
KindredSpirits
The first thing I noticed when opening the box was the quality of this exhaust. It is very well made and the welds are very precise. Seeing the exhaust tips in person was a bit surprising, however, once installed, they fit the radius of the bumper outlets perfectly. My only gripe with this exhaust is that the section of flex pipe at the front of the exhaust has a U shape which hangs lower than the rest of the system, making it vulnerable when off-roading. I do take my forester off roading, so I am inclined to have a shop straighten the bend and tuck it up, there is no reason for this section to hang lower than the rest, perhaps because this exhaust fits multiple Subarus? Install was easy and took less than two hours. The Sound: The exhaust sounds great. Has a nice rumble at start-up and idle. When you get on it, it can get pretty loud up through about 4000 rpm where the exhaust note smooths out. There was a noticeable improvement on top-end power. I love the noise, but there are times when I would like it to be quiet. Thankfully, when cruising on the highway, it is almost unnoticeable; no drone whatsoever. With an adjustment of driving style, the exhaust can be pretty subdued. I have the N1 exhaust coupled with an AEM cold air intake (no tune), between the two, I have picked up 2 psi of boost over stock. Peak boost is coming in at around 21 psi over my previously recorded best of 19 psi fully stock. Great combination for a good price. Very satisfied with the combination. (2016 Forester XT, 2.0 turbo)

I have installed this exhaust with my stock downpipe and it sounds perfect. Not too loud (for my taste), but really brings out the boxer rumble. The dual exit looks great too.

Happy! 4 years ago
WRXVT88
Even though it took me forever to get it, it was well worth the wait! Ordered the titanium tipped one for my 14 WRX, but after waiting like two weeks finally switched to this one. Once I asked they where quick to switch and send. Anyway I was suprised how easy it was to install! It took longer to install mud flaps on her then this exhaust! Took no more then an hour. The sound is perfect. Not too loud but not too soft. The low growl is amazing. I just want to keep driving all day long. It definetly sets my WRX apart from the others and that's just what I was looking for. So if your looking for a nice exhaust that looks like it's aftermarket and want a unique low pitch growl from your WRX look no further.
