I like the tone that resonates from the muffler and I like the welded construction.

It is pretty loud in the cab between 1700 and 2000 rpm. Quiet enough when cruising over 60mph. Nice deep tone with no crackle or snap. It is shorter and the inlets are wider than the factory muffler, so a short length of shaped pipe is needed to be welded in to compensate. But overall it looks good and sounds good.

Flowmaster master is as dependable as any brand you can name. You buy it for one reason, that sound. The fact that it’s quality built to last and great value are the bonus. Swapped out the dual 2.5” in by single 3” out 50 series for the same configuration but a 40 series! It my truck sounds so nice and deep now but not too loud still at idle. Great engineering!

Nice deep tone. Great construction. Only been on for a few miles and a few months but no signs of corrosion. Application: 98 5.7 K2500 GMC. Side note: stock pipes are just a little spread out for this muffler so you will need to get creative. It will not just slide on. If you’re coming from stock exhaust you will be pleased. If you’re coming from straight pipes you’ll wonder where all the sound is, but will notice a positive difference otherwise.

This is a great double 2.5 inlet and a single 3" outlet. Previous experience led me to buy this an it is great for my SS Suburban. You can tell it's a big block Chevy now 🤣!

Flowmast always has had great products! The 40 series always had the aggresive sound. Worked well on my 96 dodge. Made the v10 sound a little meaner
