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.

Installed on my stock (no bolt on) 2018 2.0l WRX and now she sings. I do have a Drunkmann stage 1 map which is awesome itself but between 2 and 2.7K there's a burble EJ style. Cold start is more pronounced than stock but far less than my previous axleback delete with resonated midpipe. Very little drone and I can enjoy a normal conversation and music at speed limit RPMs. The R400 will be noticed when you wake it up. Highly recommended!

Great sound, tones downs a bit after you brake it in. Was exactly what I expected and looking for. Step on it and it’s there. While cruising below 2500rpm it’s not very noticeable. Installation was easy and straight forward. Can be completed in about 1-2hrs gentleman’s exhaust

I was skeptical purchasing a performance catback exhaust on Amazon but I recognized the seller "MAPerformance". I watched plenty of their YouTube videos which made me more comfortable with the purchase. Also their list price is cheaper than anywhere else and everywhere is currently sold out of this item.After purchase the parts arrived in 2 days! Did not pay for fast shipping. 5 stars on delivery. The box had no damage. Upon inspection of contents everything was wrapped up in bubble wrap very well and exhaust tips had hard cardboard tubes. Everything was protected very well. Not a scratch or dent anywhere. Perfect condition.As far as install goes; it takes some time to properly align the exhaust tubes. But the tips line up perfect/symmetrical.Sound: exactly the sound you'd expect a subaru to make. Deep rumble no rasp. Exhaust sound in the cabin is pretty loud. I will be adding sound deadening material to reduce the noise. Pops and bangs after a tune.I have a 2021 Subaru STI fitment - perfect (with some adjustments)

Absolutely thrilled! First off, it was very well packaged and delivered ahead of schedule. The exhaust itself is absolutely stunning and the sound is beautiful. Gives a great aggressive tone without being needlessly loud.

Loud loud loud. Just comes to the threshold of being annoying, but falls short. Very quality for the money. Had to do some sound dampening on the rear deck lid of my 2019 STI because I actually picked up a rattle from this thing, although I think the main culprit was my plastic cheap brake light housing vibrating on the rear deck. Install was as easy as it could be. Ordered the Grimspeed adapter and did the install all alone in my garage in an hour tops. Very impressed with the fit and finish. Again, a tad noisier than I would prefer, and I’m sure my neighbors as well, but happy overall. Running 5th and 6th gear cruising speed it’s very tolerable.
