## Customer Reviews

### ⭐⭐⭐⭐⭐ Performance!
*by J***. on September 6, 2024*

I installed Borla 40358 ProXS Performance Muffler on my 2024 Hyundai Santa Cruse Turbo. I wanted more performance and better fuel economy. It has a very low growl at idle and opens up when you accelerate, with no drone, also my MPG increased by 10% too! Very pleased with it!

### ⭐⭐⭐⭐⭐ The “umph” you’re looking for!
*by J***L on October 22, 2024*

Installed on my ‘20 Sierra and it woke the 6.2L up! Very reactive, yet has a good low end without being too obnoxious. Love it.

### ⭐⭐⭐⭐⭐ Very nice sound 2016 ford Exporer sport
*by K***N on September 4, 2024*

my Sport now does not sound like its trying to blow through a small straw it added more torque and horse power but also another 1 to 2 MPG
