Does Fit 2019 WRX STI - Great Product
Install was really easy with car jacked up off the ground. Having exhaust hanger pliers helped.
The sound is incredible and it looks dope with the double walled burnt tips. I would highly recommend this axle back to anyone looking for an affordable aesthetic/audible upgrade.
Fitment says it will only work for up to a 2018 STI but I did some research and found the 2018-2019 STI exhaust is the exact same, so this WILL FIT a 2019 STI.
I would have rated Fit/Quality 5 out of 5 starts but the bolt holes in the gaskets provided did not line up so I had to snip off the ends to make them work.
Bang for your buck!
This exhaust was a great buy. It sounds great, loud when you want it quite when you needed. Gives the car bit of a rumble. Install super easy nothing hard, Just lift the car to give yourself some room.
Easy Install & Loud Results
After a couple of months of backorder, these became available again and I snatched myself up a set of titanium for my WRX. They arrived in a couple of days and were a 2 hour install on the weekend. The 2 hours entailed: not lifting the car up (was a garage/driveway job) and having my kids (5 & 9) 'help' :). I imagine with either of those variables out of the way, it's much faster. Mufflers came out with some elbow grease and creative body angles and the new pipes went in with easy. The tips fit perfectly and quickly.
The results? It's hard not to get a chuckle out of folks that ask if the results are loud; it's a muffler delete, after all. The car is loud, but doesn't sound like one of those 'fart can' exhaust setups. There's a slight drone around 3k with acceleration, but otherwise she's got a mean growl that is anything by subtle.
I'm a satisfied customer.
Great exhaust with fantastic sound
This axle back was really easy to install, plus those titanium tips looks great on the car. Sound is pretty awesome as well. Took about 15 mins total to install with adjustment. Worth every penny you spent.
Got these on 12/11/2017, it was quite a bit of waiting for the backorder but it was worth it. I wasn't sure how it would sound, as soon as the installation was done.. it was tight. It gave my wrx that aggressive sound with the rumble ofcourse! Worth it.
Good price + Sound
Purchased this axle back first thing when SubieSpeed released their youtube video. It took about 5 days (free shipping) for it to finally arrive. Everything was packaged nicely. Install was straight forward, still have to align the tips to my taste. The first start up with night and day. Can finally hear my 18' STI rumble like it is suppose to. It is loud, but not obnoxiously loud. For the price ($350.00 for 3.5 inch titanium tips) compared to Nameless ($479.00ish?) I am happy i picked Subiespeed.
