50 Series HD Flowmaster
Bought this muffler to give my Hemi some growl when you get on it. It is a mean muffler not too loud in the cab but when you get on it, it sounds mean! Easy to install took me only an hour and a half to remove the stock muffler and put this one on. Very simple only 3 clamps and done!
Not Quite What I Expected but Still Like It.
Had the #12588 installed with the Y-pipe upgrade on my 2009 Dodge Ram. This is my first Magnaflow muffler, and after watching numerous youtube videos I went with the 22" in fear of the drone. I was expecting to hear more of a difference when accelerating over stock, but I'm still early in the break in process. I've noticed a slight drone around 1500 rpms, it's not bad and could go away over time.
I was pleasantly surprised at tone and power
I put the pro series muffler on 2006 dodge 2500 cummins diesel pickup that has a 5in exhaust from the turbo back. (( the cat has been removed)) previous muffler had way to much drone in the cab it was very bad. Placed an order with auto anything had my muffler in 3 day had it put on and Boom , No Drone Quite cab and great power I mean power you can feel through out the power band IMy truck make about 450Hp and I love this pro series muffler
