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 less 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 101MM polished tip, and the exhaust hangers are welded onto the stock location of the pipes so you don't have to perform further modifications.

A silencer, as well as new gaskets and hardware, will be included to make this exhaust system ready for installation.

Invidia N1 Cat Back Exhaust!!
Marzee 10 months ago
Bought this when I had my 2002 WRX, Absolutely loved this exhaust. I ended up mating this to a injen downpipe and it fit perfectly. One thing to note is that you will want some kartboy hangers, the exhaust will rattle at low RPM's with "Stock" Hangers. The exhaust wasn't overly loud but you definitely get that low boxer rumble. Sound was about a 7/10 on loudness, could of been a tiny bit louder and I think it would of been perfect. Overall very pleased with my purchase will buy again from Invidia when I need an exhaust.

I bought this exhaust about a month ago and I love it. It was extremely easy to install, as any cat back is, and I love the way it looks. The angled tip looks phenomenal in my opinion. Invidia always makes great products of the highest quality. No doubt in my mind I would buy another product from them again.

Subie Rumble!

First off I would like to acknowledge RSD for their excellent customer service! The exhaust came well packaged so that's always a plus, This exhaust is Amazing and no video can do it justice to truly hear the Subie rumble. I just love how my car has become more responsive once i replaced my old exhaust with the Invidia N1. Overall I rate the product 5 stars and would recommend to anyone looking to upgrade their exhaust.

The exhaust makes the nice deep rumble I love about Subarus. Doesn't sound ricey like some exhausts. Came with a silencer tip as well (not my taste, but if you have concerns about noise then its nice)

  • Q: Invidia n1   Kanecamper 4 months ago


    Will the invidia n1 exhaust system fit on a 2010 non turbo forester? I know that it isn't listed in vehicles that it fits on and isn't very likely but I just wanted to tripple check,

    • A: The turbo and non turbo exhaust will be setup differently. This won't be a direct bolt on for your non turbo forester.

    I have a 2006 wrx limited, will the Invidia N1 be a direct fit to the stock down pipe?

    • A: The adapter in the link below is required. The Invida catback has a 3inch flange, and the stock downpipe is 2.5.
