Exactly what I was looking for. Produces a great deep tone worthy of the HEMI. deep growl when transmission is pulling higher torque rpm, levels out nicely as rpm's drop to cruising speed.Install was simple. I have a 2WD model with a bit less ground clearance and got it done no problem without any jacking (much safer). Tools needed: sawzall/15mm socket/spray lube/exhaust hanger plier/small lump hammerHighly recommend the hanger pliers, they're round $15 on Amazon/had to whack stock muffler couple times to free it off lead pipe once stock clamp was loose. Make sure to spray lots of lube on hanger and clamp connections.Great purchase, 5 stars. Nice work as usual Flowmaster!!

Very easy to install, all high quality here from Flowmaster. It’s the right sound for me, moderate aggressive. Nice rumble but not way over the top.

This literally took a hour to install and completely changed the sound of my truck. Gives it a nice throaty sound but not too loud. Highly recommend
