MAP Axle-Back Exhaust | 2015-2021 Subaru WRX and 2015-2021 Subaru WRX STI (WRX-4G-RMD-REV2-SCB)

Perfect makes amazing sound easy to put on and was the perfect thing to grab peoples attention

I bought this for a temporary exhaust until I’m ready for the full exhaust I want. But after having them on for almost a month it has the sounds I was looking for. No too loud not quiet either. Not a bad drone at highway speeds either. I’m perfectly happy with this product.

In the end, I’m very glad I went with this MAPerformance Resonated Axel Back. It looks and sounds amazing, and customer support is top notch! There were a few mostly minor issues along the way, but their customer support helped to resolve them extremely quickly! A+++ service and support, so cudos to their team for that! They answered any questions I had prior to purchasing and afterwards when I had some technical difficulties that resulted in damage to one of the tips. They sent out a new burnt blue tip and two new clamps immediately after sending an email explaining what had happened.

Let me again stress that I’m happy with the purchase and the resulting look and sound, which is what matters most, but there were some minor issues that I think are important to mention. Firstly, One of the resonator cans was damaged during shipping. It was obvious to me that this was caused by insufficient padding between the two cans when they were packaged, Which caused the rim of one can dent and scratch the other. This was in an area where no one will ever see it and I’m sure the road will do worse, so I’m not too worried about this.

Secondly, I had to take a Dremel to the inside of both tips because they would not slide fully on to the cans. This was because there was a small lip of raised metal around where the expansion channels were cut. I didn’t think to take a picture until after I had taken a Dremel to remove the raised lip, but it shows the area I’m talking about. I saw this mentioned in another review who said they had to remove this lip with a dremel as well. This worked to fix the issue so moving on.

Now to the main reason I deducted 1 star. The clamps they provide weren’t sufficient to hold the tips on even when tighten down to the point of breaking the clamps. There were no instructions provided in the box, and the instructions provided online do not mention a torque spec for these clamps. I saw the reviews people mentioned breaking the clamps and having to use a more heavy duty U-style clamp, So I tightened them down as far as I felt comfortable until I could feel them bending and It still wasn’t enough to hold the tips on securely. This caused one of the tips to come off within a minute of the first drive. I watched it bounce up the road behind me and honestly, I was surprised at how little damage there was. I believe this speaks to the sturdy construction and materials they use! There may have been some user error involved, but the lack of clear instructions and the clamps definitely contributed to the problem.

I typed up an email and sent it to the customer support team and they were extremely responsive and amazing to deal with! He apologized, gave me some helpful info such as the proper torque spec for the clamps, and most importantly sent me out a replacement tip and two clamps to replace all the parts that were damaged!!!

I do want to say that instead of using these clamps I went to my local parts store and bought two heavy duty U-style clamps to use instead and so far these have worked great to hold the tips in place.

So in the end, I’m extremely happy that I bought these fromMAPerformance. They look and sound amazing, which is what really matters, but on top of this they entire staff was great to work with!!!

Definitely has a nice deep sound coming from stock. I don't hear much drone from inside the car. Great inexpensive mod for a daily . On a positive note, the customer service is great. I lost one of the tips on the highway (user error. not as secure as I thought I had it) and MAP sent me one free of charge. I was expecting to pay since it was my fault but they hooked me up. Continued business for sure.

Sounds amazing, welds looks amazing and install was super simple and quick
