Review: Amazed By the quality and Performance - Wow , Just wow , i am amazed at the quality of this product , I have a Focus st it had a straight pipe exhaust on, on 3000 rpm it had 100+ db , after installing this muffler it has dropped down to 68db ! and no power loss whatsoever . It is a very quiet muffler , if you need something more aggressive borla has other options , Thanks to borla team , I am proud That i am a Borla muffler owner , i will always use their products from now on
Review: Loudness - BORLA PRO XS review: I initially put two Carven R mufflers on my custom 1981 corvette. It was crazy loud! It was so loud that it was hard for me to gauge how fast I was accelerating when on the gas hard. Even just cruising through my neighborhood, it sounds like I’m flooring it! Too loud. So after several online searches and reading others review I decided to try the Borla Pro XS. I bought two ( dual). Omg here’s the biggest difference. It’s a tad bit quieter but because it has such a DEEP DEEP grizzly bear tone it takes away all the crackling sound from my camshaft which makes the overall muffler sound very nice, tolerable, and more pleasant to drive, and gauge my acceleration when hard on the gas pedal. It’s perfect for being very aggressive without upsetting your neighbors. And by the way my neighbors is a cop! I recommend this muffler to anyone who’s a true restomod enthusiast that still appreciates that muscle car sound but is also respectful of your neighbors too.

### ⭐⭐⭐⭐⭐ Nice growl
*by D***. on July 11, 2025*

I put this muffler on a Ram 1500 limited , wanted a little more growl without being obnoxious. This is perfect , love to hear it bark when I get on it , and love the quiet when I’m just cruising. Couldn’t be happier, zero drone. Took a couple months to really mature the sound of it, but it is exactly what I wanted when I purchased it.
