I am looking to buy a SLP exhaust system. Which system sounds better, the "Loudmoth II" or the "Power Flow" system. I am looking for a very deep muscle car sound. Any advice will be helpful

 

I think the Power Flows are the quiet ones.

My buddy has the LoudMouth (I think IIs) on his Mustang and they're really loud (without cats) but they are very muscle car sounding.

For a truck, it should be a bit quieter.
