I have an '04 FX4 screw with a stock exhaust and gotts mod. I am wondering if there is a muffler i can put on to get me a deeper sound without making it too loud? I don't want it to be too loud because I use my truck a lot for hunting, but I would like to get a deeper sound if possible. Thanks

 

Too many options to list. Check out the "tube" for some videos to get an idea of what you like.

 

x2 on checking you tube

 

x3 on Youtube research, but, to state some facts to set you in the right direction faster, stay with anything straight through in design, no chambered mufflers ( Flowmaster, Cherrybomb, Edlebrock, certain Summit ones.. ) And absolutely no glasspacks.

Look into Magnaflow, or the king of mufflers, Borla.
