I have been looking around to find out what mufflers are direct replacements for my 2000 3500 truck. Stock muffler has two pipes going into the muffler and one coming out. My 2000- 2500 has the same thing. I looked at a few sites and can not figure out what people have replaced there stock mufflers with. Anyone have a suggestion and feedback? The body style of my trucks are the same as 88-98Thanks

 

Just spent another hour reserching this, whats up am I missing something here or what, millions of these trucks out there and I can't find an answer. What are they doing for these trucks that have the two into one design. about the only thing I can think of is either duals or some type of y pipe or somthing. I'll probably go to the exhaust shop tomarrow and ask the guy. I'm feeling really dumb tonight.

 

magnaflow has a built in x pipe in there mufflers. two in two out. any manufacturer has a two in one out muffler.

 

There's a bunch of aftermarket companies that a make dual inlet, single outlet muffler... Are you looking for dimensions or something??

Edit: Like here is a Flowmaster 50 series
