Review on 🔊 Borla 400286 ProXS Metallic Muffler - High Performance Exhaust Upgrade (4 inch) by Russ Freeman

At first glance it looks like a high quality silencer. After installation, it sounded great, performance is good too. BUT only after 2 months it started to fail. The muffler body falls off, resulting in very annoying noise, poor performance and poor fuel economy. Revain immediately sent me a new one and the SAME SAME happened in the same timeframe! I expected more from Borla as a reputable brand, but I learned my lesson and chose Mangaflow. Thicker steal, same power and sound, and it seems like it's going to last.
