I am thinking about trading in my 07 5.9 for a 08 Mega Cab 6.7. Have they figured out how to make the exhaust work better on the on 08's or do they still have issues?

 

pretty much all the issues are fixed with the DPF clogging. With each new flash the problems seem to become less and less. And the aftermarket world is catching up to the 6.7 too.. New performance toys coming out each month. But you have a 5.9.. a very solid engine. I would keep it if i were you. give the 6.7 another year and switch if you really feel like it.

 

I now have a need to haul clients around and the Mega Cab would fit the bill allot better. I really don't want to buy another truck seeing as how I've had a 06,07 & possibly a 08 to many trucks. Thanks for the help

 

On the other hand, your clients will surely appreciate the added room of the mega. I know my kids do! Throw'em in the back with the DVD player and head phones and five hours later arrive at destination without having heard a peep.
