### ⭐⭐⭐⭐⭐ Helped quiet down triton v10
*by A***X on March 1, 2026*

Installed a flowmaster 40 to replace the old rotted muffler on a triton v10 motorhome, ended up being the worst sounding exhaust ive ever heard in my life. Ordered this flow fx to install before the 40, helped quiet down the system and make the note bearable.
