  • Great exhaust, nice throaty purr
Great fitment on my 2016 wrx. Basically comes in 4 big pieces (two mufflers, t pipe, mid pipe) and with screws and fittings to connect them all. Be aware that if you're using a stock j pipe you will need a donut adapter to connect to this mid pipe. If you're using aftermarket (I use a mishimoto j pipe), that adapter will not be necessary and you can just use one of the supplied "washers", for lack of a better term. Install was very easy - only took about 20 minutes to install. Uninstalling the stock exhaust is a WHOLE other question and took about an hour and a half due to lots of rusted out bolts etc. If I have any complaints it's that there is no instruction or guidance at all that comes with the exhaust. Plenty of youtube videos to see what you're doing, but some manufacturer guidance on, for example, to start at the mufflers or at the mid-pipe would have been very helpful. Nice throaty tone on the car - love it. Does drone a bit on the highway, but at a tolerable level. Comes with silencers, which I will likely use on early mornings on cold days to avoid waking the neighborhood. Love it. Makes the car sound the way it should have from the factory. ... show more

  • 5 stars
Just had this installed on my 2015 wrx premium and love it. It sounds great without being abnoxiously loud. The guy who installed it does exhaust for a living and he said that "it fit better than the OEM". I have only driven it about 15 miles and it seems to be performing better. Note: I have no extra mods and have not tuned. ... show more

  • The product fits but takes some good installers to make sure it is done right
The product fits but takes some good installers to make sure it is done right. You get about .5 inch clearance from the right crossmember and barely that to the drive shaft too. If not done perfectly, the install either hits the crossmember or worse (hits the drive shaft). I had to have the exhaust re-installed as the first installer put it too close to the rear cross member. ... show more

  • Awesome sound!
I found no issues with this exhaust whatsoever. It sounds AMAZING on my 2015 STI. It was between this and the Q300 and I am glad I went with the N1. Be warned, however, that the 2015 WRX do not have unequal-length headers so it won't sound the same as a STI.
