What Kind of mufflers have Little drone, But are still pretty loud on the outside? I have been running straight pipes on 2 different trucks for about 2 years now and the noise inside just gets to you on those long road trips, and i'm headed on one in a few weeks

 

if you were running straight pipes, any muffler at all with sound a lot quieter inside...

i have the flowmaster super44, which is one of the more aggresive mufflers on the market, and long roadtrips on the highway are no problem at all.
