Right now I have true duals dumped right after the rear axle. They go through 2 magnaflow mufflers, that are just a little too quiet..

Interested in getting one muffler, 3" dual in, with a single out...
Looking to put it in front of the rear tire...
or maybe behind the axle like I have now..

My truck is a 6.0 liter but is stock

Ive heard a lot about the corsa sport being good for cruising speeds until you really get on it..
Im looking for something like this...any opinions...

 

pull one Magnaflow out. They're mellow untill you mash it. I had the 14" case

 

So have one pipe with a muffler and one not? lol
