Flowmaster 8524553 Super Muffler 409S Review

Installed on my 2018 Toyota Tundra 5.7L Double Cab. Great sound compared to the stock model, with a nice growl on start and a low rumble with a little rumble at highway speeds .

The muffler shop charged me $180 to have it installed…

The only downer is the more than acceptable hum at 1800-2000 rpm on medium throttle. Slight incline/hill. boom guy. Maybe episode 70 would be better here.? I still like it partially and fully. would i…

Almost perfect fit for my 2017 5.7 Tundra Crewmax, just had to add a few inches of piping to compensate for the shorter muffler. It sounds great, slightly louder than the original while driving, but when you press it you notice it immediately. A very light drone cruising at about 60 km / h does not bother anything and you can still have a normal conversation. There's no noticeable loss of torque at low revs, but you can tell the engine breathes better. This is exactly what I was looking for…
