I have a 5.7 hemi and it sound great. I turn heads every where I go. It is on the loud side When you are on the highway if you go over 1500 rpm you do hear it , so anything over 60 in my 2004 is kind of loud on a long trip. The sound is awesome

I am siked, excited to install in January

Exhaust looks great on my 05 Dodge Ram 1500 Hemi Sport. Just not as loud as I had hoped. I am thinking about switching out mufflers but I will see.

Sounds awesome! Took a little longer than I expected to install but overall pretty straight forward. Only extra steps needed were to weld pipes to either side of the muffler due to wiggle when clamps tightened up all the way. Well worth yhe investment.

excellent increase!

love the sound of this system! the performance gains and mileage increase make this system well worth the money, not to mention the material which is sure to last!! i paired this system with a K&N FIPK (Fuel Injection Performance Kit) intake and finished the look with Borla twin tips; can't say it enough, LOVE THE SOUND!!!

On the 2005 Dodge Ram 1500 Quad Cab with the 5.7 Hemi. Its very noticeable at 65 - 75 MPH (1800 - 2200 RPM). Not very happy with the sound at those RPMS. Other than that it is what was expected and from a California company, which is a good thing!
