Ive been running my super 44 for a year and love it hardly no drone at all. Recently i purchased a trailer and all of a sudden the drone is SOOO bad. I am wondering if it is actually the muffler or is it my 4 inch tips echoing off the trailer. Is there anyway i could fix this problem like smaller tips or diffrent exit of the truck or differant muffler. Please lets not start this flowmaster is bad and all that crap unless you really think its the muffler. I want to keep my sound level as it is now. What are my choices. i have the si/do super 44 with 4 inch tips running straight out the back

 

That's the problem. You'll either need to change to 135 or 90 degree exits to help alleviate the echoing. You could also have the tips exit Lightning style infront of the passenger rear tire...

You also need to get rid of that Slowmaster...















J/K!!!!

 

45 degrees out the back behind each tire. lightning style in front of the rear tire will create too much drone. 90 degrees just looks weird.

And you need to get rid of the slowmaster




















seriously
