The stock-down pipe on your 11-16 6.6L LML Duramax is not doing you any favors when it comes to performance and sound. Installing this drop-in unit from PPE will allow exhaust to exit the turbo quicker which nets you more power and lower EGTs. Plus the heat wrapping will keep the heat in the exhaust, not the cab. It’s a win-win-win.
