I just ordered a SISO magnaflow (15821) to replace my old Flowmaster super truck style, will I like the mags better than the flows in terms of power/sound?

 

Power yes you will, Sound i couldnt tell you becuase i dont know what you like!

 

I sure as heck did. I had Flows on my last truck, they droned too bad all the time for me to want them on my new truck. There was no question when it came time to do the new truck, Magnaflow all the way. There was no way a Flow was getting close to my truck. I swear I lost some power with the Flows, but you can't REALLY tell much from a butt dyno.

 

The drone is why I decided to change, heard good things about the mags.
