Review on 🏎️ Enhance Performance with Flowmaster 8042541 2.5In/Out 40 Series 409s Muffler by Tyrazz Abouzar

I have a 2001 Chevy Blazer ZR2 4x4 4.3 V6 and wanted a deeper sound from the muffler. This muffler adds the perfect amount of sound I was looking for. I was hesitant at first as the Flowmaster website said this 40 series is an aggressive muffler with noticeable internal noise. I don't find the sound much more noticeable than my old stick. There is no hum and I can hold normal conversations and listen to my music like I used to. I had it installed at a $60 muffler store in about 30 minutes. They had to add about 6 inches of extra pipe and this muffler is slightly smaller than the stock muffler. I have a full stock shot and a cat. After leaving the store I hardly noticed any improvement in the sound, but it took a few days for it to really come to life. I'm sure the sound is much deeper with the V8, but it suits my needs perfectly.
