1.75" primaries.

 

i plan to do a true dual setup with aerochambers. would you recommend putting in a 3 inch expander on teh end and running 3" the whole way, or just keep it at 2.5". i plan to have a street truck. drag strip probably twice a year, and tow.

 

Dual 2.5" will be fine, unless you have a big blower.

 

Mine came today I may toss them on in the AM:

 

I would stay 2.5"

 

They still have some 99-01s left what would need to be done to pu them on a 04?

 

to make a few block off plates I think.
