Super Easy Installation, bolts that came with the exhaust were to big to fit through so i had to use the original ones but not that much of an inconvenience. Besides that looks great, sounds great, gave my wrx more of a rumble and even some little pops.


We appreciate the 5 Star Review! The Invidia N! Cat Back Exhaust provides amazing exhaust flow, reducing back pressure and adding tons of performance! On top of that it sounds fantastic!


Very nice build CAT back system

Was really impressed by both quality and design, this system weighs very notably less then the stock system and the wields on the hangers and on the muffler are prefect dimes and i loved that very nice little detail and the my favorite detail is that the hangers are measured perfectly . I would give this system 5 stars but the hard ware that comes with is aimed for a matching down pipe, the gasket doesn't seal with the stock down pipe that uses a donut type gasket (2016 year STI). the bolts supplied are sized to fit a matching system and don't not work on the stock down pipe, so to the people buying this system and will still use the stock down pipe youll need to get 2 bolts to fit it to the stock and a new donut gasket cause the flat one supplied will not seal properly. After installing the system I got the Invidia down pipe a little later and this system sounds really good both with and with out the down pipe but the down pipe is the way to go.


We appreciate the positive review! The Invidia N1 Cat Back Exhaust is a fantastic mod for your WRX/STI! It sounds phenomenal and the design allows for the best flow for increased HP! Anytime you are trying to bolt up an aftermarket exhaust to an OEM downpipe you will need the catback adapter to maintain the donut gasket!
