Flowmaster 70 series big block

Overall, I am happy with the muffler. As my daily driver and primary family vehicle used for traveling, I didn't want anything too loud. This muffler is a little louder than what I expected, comparing to a 50 series installed on same truck. I removed the 50 series last year and had to go back with the factory muffler due to a drone when pulling my trailer or boat. Using Flowmaster's sound chart, I thought the 70 series would be only choice as it looked to be the quietest muffler Flowmaster makes

nice sound

i have had the 3"muffler on my 09 silverado for awhile and very happy with it. It sounds great and keeps getting better. It took a tenth off my 1/4 mile with the tail pipe.

Quiet yet still sounds good

This muffler I think would be better suited for a larger engine. My HEMI on my new Ram doesn't give it the echoey sound I hear on other Flowmasters. Going to order a 50HD series soon

Great sound

I have a 2005 chevy 4x4 2500hd. Had 40 series and hated them I'm 52 years old and they were too loud. The 70 series are great good deep sound and not so loud.
