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 pair 101MM 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.

Great exhaust!

This exhaust sounds great and looks awesome! Easy to install. If going to a stock downpipe, get the grimmspeed adaptor and a new donut gasket. The old gasket on my 2012 WRX was crumbling in some areas. You'll want some penetrant like PB Blaster for the bolts and hangers and it also helps with cleaning the piping where the old gasket was before putting the new one on. Stock hangers work perfect and provide a tight fit with no movement. Volume on this exhaust isn't as loud as some of the horror stories say (at least with my car that still is running the stock DP). If you want an idea of how loud it is before buying, pop off your axle back portion (after the intermediate pipe) of the stock exhaust and drive around like that briefly. I drove on some chunky roads to a mountain bike trail head that yanked my exhaust apart at that location which prompted this purchase (saving money for a lift) and can attest to the volume being pretty similar to that, but with a nicer, lower rumble.


Love it!

I ordered this on Black Friday. UPS delayed my shipment by one day. I received it within 2-3 days after ordering it. I am in California so it doesn't take long to get here. I received the package and 100% good condition. I inspected everything and it looked great. I installed this while it was raining with my brother in law. It took us less then 45 minutes to install. No frozen bolts etc. N1 is really loud. My neighbors are going to hate me now LOL. I definetely recommend this item. THANK YOU RSD

Spent 8 hours trying to remove frozen bolts, used every product known to man and couldn't do the install. Gave $110 to the local muffler shop and they did it in an hour. I would not recommend doing this yourself unless you have a lift and plan on cutting out your stock system. The sound is very deep, just what I was looking for. Good product for the price.

  • Q: Loudness  WrxonWrxOff 5 months ago


    How loud is this exhaust compared to other cat back exhausts? Measurements in DB?

    • A: Unfortunately we do not have the exact measurements but this is one of the loudest catbacks we sell. Please refer to sound clips that we have posted on our various pages.

  • Q: Fit a sedan  Lapissti 5 months ago


    Would this exhaust fit a 2008 sti sedan or just the hatchback

    • A: This will just work for the Hatchback and not the Sedan do to the over length differences between the vehicles.

  • Q: Gasket for my Perrin downpipe?  jlockett 6 months ago


    Good afternoon, I am trying to figure out what size gasket I will need for this N1 and my Perrin downpipe on my 08 STI hatchback. I believe my Perrin is 3" and it appears the N1 is 3" as well I just want to make sure I get the correct gasket. Thanks

    • A: This exhaust comes with a 3 inch, 2 bolt gasket for you to mate up your 3 inch Perrin downpipe. Everything should mate up just fine.

  • Q: Compatibility rear attachement Q300 and N1  Q300 and N1 rear attachement 8 months ago


    Hello, I have allready the Q300 on my 2011 sti hatchback. Can you please tell or confirm me if I can switch only the rear dual muffler between the two Without touch the middle pipe. Tanks a lot. Best regards. Do I need anythink more part to install it?

    • A: It does appear that the N1 and Q300 do share the same midpipe section, however we cannot 100% confirm the cross compatibility and you would need to contact Invidia to see if they have more info.
