Review on 🏎️ Thrush 17718 Turbo Muffler: Unleash Your Vehicle's Performance with Superior Exhaust System Efficiency by Carlos Henley

Fit this to my Jeep GC 04 4.7L in place of the Thrush double glazing that was in place of the stock muffler, the cats are still there. It sounded good, but the rumble at 2100 rpm, right at 75 mph, was just insane. This muffler has completely fixed that, it's a lot quieter but still has a little hum which is good.
