Flowmaster Outlaw 817633 Direct-fit

I'm 64 and I love this set up! Installed this on my 2016 RAM 1500 and it sounds great. Very aggressive sound and volume without any drone, but be warned you hear the exhaust note inside the cab....always. Keep your neighbors happy and take it easy while departing and arriving. The 817633 wakes up that 5.7 Hemi, oh ya!

Name says it all. Gives it a really nice growl over the stock exhaust. Had the old removed and the new installed in just over an hour.

Excellent Exhaust!

The product and sound are great. Installation was a bear. I could not get the exhaust pipes to come out of the factory muffler. So I ended up using a hammer. Took over an hour to get apart; 10 minutes to put together.

Flowmaster Outlaw Series is the only way to go. I put the Flowmaster Outlaw direct fit muffler on my 2013 Dodge Ram and it sounds fantastic. I sure am glad that I opted for the Outlaw Series muffler over the American Thunder Series. I haven't noticed any difference in gas mileage but, who cares..... I didn't make this purchase for that purpose.

Perfect Sound

My new outlaw flowmaster slip on exhaust muffler has the perfect sound. It is not loud in the cabin and annoying in the outside during acceleration.

They'll hear you coming!

This exhaust installed in less than an hour. Presoak the clamp bolts and hangers prior to installation and your old exhaust will come off fairly easy. The sound is great at low rpm's, does have quite a drone at speeds above 75 mph. If you're on the fence about the sound get the American thunder muffler.
