I am going to be getting a flowmaster 40 series muffler in a couple of days and i was wondering if i should get dual pipes coming out the end or just 1 like it has now, does it sound any different with 2? sooner or later i am going to get 2 mufflers and make it a dual so should i just go with 1 for now? Thanks. by the way here is my truck.
