i am cheep

i put a cheep turbo muffler on my truck, at an idle it sounds decent with some rumble. well as we all know cheep mufflers dont last, this is what i was counting on and i was hoping it would get louder with time. well it did but inside the cab it howls at bout 50 or 55 and at 60 there is hardly any noise the exit is run out the side in front of the rear tire

is this right??

 

You already have the answer, don't you? You hate this thing, get rid of it ...life's too short....get one you like...listen to this board at what does sound nice if you have to.
