hahah your car is the total opposite to rice mate - dont worry about it!!
(4 door family cars haha - kididng )
if you dont have time, go see Gary at northshore performance exhaust in hornsby or any other exhaust shop around you at the beaches and ask bout the middle muffler being removed - when I had my rear resonator on my LS1 removed into straight through - was only 60 bucks!
Hope that helps Ben!
Cheers,
Chris
