Review on 🚗 MagnaFlow 4in Round Center/Center Performance Muffler Exhaust - Straight-Through Design, 2.5in Inlet/Outlet, 14in Body Length, 20in Overall Length, Satin Finish - Classic Deep Exhaust Sound by Glenn Cho

Without the bladder, it's not for everyday driving. I installed Magnaflo in my Jeep JK and saw a huge increase in fuel economy. In one month I spent twice as much as usual. Of course, that has to do with the functionality of what a silencer should do on a vehicle. The sound of the drone coming out is very loud and overwhelming in the car, in my opinion. I don't think there is a difference in running an open pipe without a muffler. I will end up saying that you are better off saving your money and just cutting off the stock muffler. You get the same results. I ended up reinstalling the old muffler.
