Hey guys.. on my picture you probably see the big tip out the back. but today i changed it up a bit.recently ive had the catalyic converter taken out replaced with a piece of 2 1/2' pipe up to the magnaflow muffler, with a 3" turndown. boy did it change the tone. Its decently loud inside the cab.. and you can hear the truck lope very well. On the outside it vibrates the ground a good bit too.

 

post more pics and a sound clip. what you've described sounds good.
