I found a decent deal on a banks cat back exhaust for cheap, question is it was off a 2005 2500 6ft bed and is currently on his new truck 07 mega cab

i am asking whats the different between the 6ft and 8 ft bed exhaust

also will it work on my 2004 3500 8ft bed it looks like it will?

 

Usually the exhaust is cut between the downpipe and the muffler to fit a short bed, otherwise the system is identical.

The Megacabs are on the exact same chassis as a quadcab longbed from what I understand, so it should fit on yours just fine.

 

thanks alot !
