The media could not be loaded. 2020 WRX. A great deal for the money! Fits perfectly! Comes with everything you need and fits like a glove. Clearly made by guys who care about what they are doing and make of affordable. Thank you guys! Installation is easy if you know just a little bit about what you’re doing. The hardest part is actually your stock bolts. After you chew that, it’s a pleasure to work with. Sounds just awesome! Not too loud, but rumbles like it belongs there. ... show more

    • Sounds great, louder upon cold start but definitely not obnoxious at idle.

The media could not be loaded. Sounds excellent, finish looks amazing. I was going to return it bc I was worried it would be too obnoxiously loud and wasn’t interested in upsetting neighbors when I cold start at 3am for work lol. But decided to go ahead and install it and I’m glad I did. The sound is only louder during cold start n once it idles down to normal it’s pretty quiet. I drove it around a little bit and went into a parking garage and it definitely puts a smile on my face hearing that crackling when rev matching and the pop when shifting. Definitely going to keep me entertained for a while haha. The fit was perfect. instructions said to have 2 ppl, one to align and one to tighten the bolts. I was able to do it alone in less than 30 mins. Jacked it up under the rear differential and just removed the old mufflers and rubber hangers, factory bolts are 14mm the new is a 15 and 16mm. Put the new one on and just finger tightened the bolts n gave them just enough to keep it from moving while I made sure it was aligned n once I knew it was I went ahead and finished tightening. The welds are literally perfect imo. Like others have stated, get it while it’s more affordable than other big name brands. ... show more

The media could not be loaded. I won't lie, I found this exhaust thru a Facebook ad and was suspicious but after I looked at remark and other brands axel back exhausts I couldnt get over the price of this one! Shipping was quick (under a week) and when it came I inspected the welds and was surprised with how good they were. Install was really easy, did it in about 40 mins by myself, hardest part was breaking the rusty bolts (still not that hard) and getting the stock muffler off the hangers. Overall, I'm more then happy with this axel back exhaust. Adds a great sound, and amazing look to your WRX, plus it was so much more affordable then other brands. ... show more

    • Amazing for the price!
The media could not be loaded. Video is shown with intake and catted downpipe. For the price, I'm super impressed on how good it looks and sounds. Had no issues with packaging, all hardware were included, even replacement exhaust hangers. The burnt tips had no scratches or defects. I came from a Nameless axle back that had small mufflers (on the car when I got it) and these no muffler axle backs really opened up the sound and gave it a much deeper growl. Had some struggles lining up the tips so it wouldn't touch the bumper, but some adjustments were needed with the midpipe and it's on perfect. Definitely worth it for more than half the price of other brands. Highly recommend! ... show more

These fit amazing. Did the install in my garage with just the correct size wrenches. The price is cheaper than most other axel backs and actually includes all new hangers and bolts unlike some other brands. The ton is great. Mellow and deep, not over the top at all and burbles a little on down shift. Overall, for the price, these can not be beat. 10/10 recommended ... show more
