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

Great price for a great muffler! Put this on my 2008 Tundra (5.7L) after a dual exhaust rework. It first started with removing the muffler, which made me really loud and proud, but also created more back pressure than I wanted. I felt the difference immediately after installation. Much quieter than removing the muffler, which I'm sure my neighbors will appreciate at 4am. I can absolutely recommend and I would buy again. Very satisfied!
