For a strong boost in power, the Invidia pipe offers an alternative to other power-boosting enhancements. To see just how much power the Invidia pipe can produce, a quick look at its dyno chart shows it easily added several horse-power units to the stock exhaust system. Each Invidia pipe features a large 4-in stainless-steel Bell mount to enhance power by fe excess gas. It sports a one -piece design, eliminating the need for the stock catalytic converter. In addition, each Invidia pipe can be bolted up to any Invidia exhaust or a stock exhaust for an easy installation.

Had to return it cause my clutch broke but I’m sure would’ve sounded great getting another one soon

I was pretty excited to get this exhaust system. Had one before a few years ago. Maybe this company has gotten too popular and they are mass producing them faster than quality control can keep up. I recommend if you order this definitely have a exhaust shop install it. We had to tweak all the hangers and that still didn’t work. If you look at the picture you can see where we just cut the system and added an inch to the passenger side. I guess I should’ve just sent this piece of junk back, but as my old system lay there I kind of felt committed… I will definitely do more research in the future and buy a more quality set up. But who am I kidding with tax and all it’s almost $1300 !

This is an amazing exhaust system! The sound is incredible and really wakes up your WRX or STI! I have it on my 2021 STI and it sounds powerful and loud at wide open throttle. If your looking for that loud deep rumble then this is the exhaust system for you! Many will say it’s too loud inside the cabin but what’s a Subaru STI without that signature rumble!? Buy it, your subie will thank you!

Looks and sounds AMAZING !!! After install Love the subie Rumble. A great deep tone after it is broken in. Tips look very nice 😎Driving it is comfortable noise. Highway speed no drone unless your going 85.If ya hit it sounds very good.Compared to stock exhaust alot louder but not obnoxious. Go with the R400.

I like how this exhaust made it sound not only louder but deeper as well and it was pretty easy to install. It took me and a friend about an hour to take off the stock one and bolt on this one. Pair it with an Invidia downpipe for an even better exhaust note.

Bring out the rumble on your sti. Sounds like a monster. You do need to shave a little bit of the inside of the driver side back diffuser because the tips lean more the right. Not a deal breaker at all. You can’t even see where i shaved it

I was really happy with how quickly this arrived first of all. Some other companies might have it for a little cheaper but it was worth the little extra that i spent to get it within a couple days. I must warn though that at first the exhaust sound will be very obnoxious and almost hard to deal with. You need to let the exhaust break in. it took about a week of driving with it on before it broke in and the drone went away. As far as the exhaust it looks great and sounds great too. If you're looking for an exhaust that isn't super loud this is the one for you. Although it does bring out the Subaru rumble its not annoyingly loud. I also should mention if you have the stock down pipe you will need an adapter since the stock downpipe is 2 1/2 inch and this exhaust is 3 Inch piping. All in all it's a little more expensive but worth it for a great sounding and looking exhaust as well as the fast delivery.
