I've been looking for a dual exhaust for my 4.7L, and every 4.7L exhaust option I find says "for 4.7 and 5.7" but theres a lot that just say they are good for the 5.7L. Can I buy any exhaust for the 5.7L for my 4.7L as long as it fits my cab size?

Then others say 05-10 - Was there a change in '11 or were these just never updated?

 

Someone has got to know this... No other 4.7L drivers out there???

 

where did you look? i found mine for a 2009 and there was no difference on the 4.7 and the 5.7L.

 

call the dealer and ask for the inlet/outlet size for a 2011 4.7 and a 2011 5.7...then if you match the pipe sizes it'll be fine.
