Subaru Stage 2 Power Package STI 2015-2019, STI Type RA 2018 is rated 4.7 out of 5 by 409.
Rated 5 out of 5 by from 2016 FXT Bought this during the Black Friday Sale. I had a bit of trouble plugging in the connector to the port, first three times it woudl not connect. You think it's connected, but you have to take it a bit further and really push it in hard. I thought i almost broke it. Since I loaded the Stage 1 93 Map, the power delivery is much smoother and earlier, provides much more usable power at the low end. There is no more power surge at 4k. It used to be ...nothing nothing nothing ... OH SNAP! now it's more like it starts pulling right away and pulling all the way to redline. On my daily commutes I've also gotten gains up to 29.4mpg.

Rated 4 out of 5 by from 2015 wrx accessport So i have had a 2010 wrx before and had an accessport and many other mods but this difference on this product is more on the stability and ease of driving the vehicle, the gas pedal was very touchy and boost response was All over, but now after adding this its has made the starting from 1st gear and low gas mileage shifting so much smoother. The boost response is better and doesnt even tickle boost unless you want it to. Im sure the gas mileage will go up from my already 26.7 mpg. As far as power, it has gained some power at the low end which im very pleased with but havent any hard time on the car to let you know about higher end power ranges

Rated 5 out of 5 by from First Impression I just installed the 93 Stage 1 OTS map on my 2015 WRX this morning. The installation was seamless and only took a few minutes. I drove it to work, mostly on the highway, and got 39.6 mpg over the 22 mile trip. The car is definitely easier to drive smoothly. The power delivery is much smoother and more linear than stock. The stock vehicle had a couple (extremely annoying) points it the power band that felt like I was lifting off the throttle under acceleration. I haven't pushed the car since the tune so I can't comment on the power increase, but, in my opinion, the driveability and fuel economy improvements alone are worth the price.

Rated 5 out of 5 by from Very impressed Have to admit COBB did their homework on this tune. I have about 7000 miles on my WRX and this tune completely changes how you drive it. It’s so more REV happy and just climbs up to redline without falling on its face like in the stock settings. Also noticed it makes the car more drivable for beginners with the change in throttle response. Subaru always makes their cars very sensitive on how lightly you apply the gas. Maybe Subaru does this to make their cars feel faster IDK. Just now I feel like it will be easier to teach my wife how to drive stick with the COBB tune. Would defiantly recommend this product to any WRX owner.

Rated 5 out of 5 by from High Quality Craftsmanship I bought this exhaust to replace the Q300 from my 2015 STI. I am most impressed with the quality of the craftsmanship of the exhaust. The welds, the bends, its mirror-like polish, the laser-etched tips, everything... it's a gorgeous looking exhaust. It took me some time to find the right adjustment. But the fitment is perfect; no rubbing, rattle, clanging, etc. I really love the sound it produces. It's a deeper tone. The sound level is in check by your right foot. Even under wipe open throttle, I appreciate the tone I hear. It loud enough to be noticed within close proximity; not a mile away. No droning on the highway. I am very satisfied with the finish product. I enjoy driving my STI more so than ever before.

Rated 5 out of 5 by from Makes the STI more drivable I have been running the 91 octane map for the last week and could not be happier with the Accessport. The factory S# setting drove me nuts with how twitchy the throttle was. After installing the Accessport the throttle modulation is MUCH better in all modes. The other major thing the Accessport fixes is the dramatic drop in power right before redline. The "I" mode works great for around town when you don't need all the power from the car. There is a noticeable increase in power with the Accessport installed but the major improvements are with the drivability of the car.

Rated 5 out of 5 by from Significant increase in performance... I purchased the Cobb Accessport for my 2016 WRX CVT about a month ago... Currently my setup consists of: Nameless Muffler Delete Exhaust and Apexi Drop In Filter... The stock tune from the factory was very inconsistent with peaks and dead spots when accelerating... It also created a jerky ride that some have mentioned... Since the addition of the Accessport, it has transformed my car... Now it's fairly quick with lightning shifts... The peaks and dead spots are now gone... And its very linear and robust for most spirited driving. By far the best performance upgrade so far... Thanks Cobb...

Rated 5 out of 5 by from Does what it says on the tin. If you're looking at one of these you already know what it does and why you want it. It does exactly what you expect it to and there are no downsides or warnings required. Install was dead simple from actually installing in the vehicle to flashing maps. Product came with everything I needed. Had some difficulties ordering and support was super responsive and helpful. Oh, and flashing a Stage 1 map fixed the super dumb WRX accelerator pedal mapping and hugely ironed out the entire driving experience. I don't really plan on installing much in the way of mods for quite a while, but it was worth it just for that.
