Review on 🚘 Flowmaster 430402 3In (C)/2.5Out (D) 40 Series Muffler - Optimal Performance & Noise Reduction by John Douglas

This is a classic and iconic muffler for all truck owners who want to fit dual tailpipes and get a nice deep rumble. I put this on my dad's 2004 Silverado 5.3L after removing the catalytic converters and it really roars like an old school truck. Sounds great when starting, idling and in motion. Full throttle isn't as loud as other makes of truck, but I think it's common with Chevy LS engines. All in all this is a great silencer and it was a good buy. I would recommend finding a stainless steel version to extend the life of the muffler.
