Yup, changing from 40's to 50's is easy. just cough up $150.
WOW, you better find a better dealer. Besides, you can always find another vehicle to put the 40's on.
The reason I said it the way I did was meant that the system wouldn't have to be spliced, hacked, butchered or changed. Just need to cut about 3-4 inches out to fit the 50's in,
