on my exhaust i have true dule pipes all the way from the manifolds back to the mufflers. the pipes are 2" in diameter. the manifolds are also ported to about 2" also. i was just wondering if the exhaust setup is good for a free flowing exhaust becuase i was wanting to install a 5% sc pulley and wanted to make sure it is safe to run with the type of exhuast setup that is currently on my car.
thanks
