My main reason for a 340 in a 22' is for the cat system which cuts dow on emissions and should offer a marginal efficiency improvement with the extra 02 sensors. Good to know that the 340 is enough for the 24'. I'm like the added space of the 24 but don't think I would be taking advantage of it frequently which makes the 22 more appealing to me.

I have found an 09 22 that looks good but needs upholstery work on the back bench and seat behind the driver which has turned me off from it.
