Ok, cool.  So, the stock exhaust is 2.125" dia pipes (x2) right?  The Stebro is
2.5" dia (x2) pipes.  So total areas:

Stock: (2.125/2)^2 x 3.14 = 3.55 x 2 = 7.1 sq.in.
Stebro: (2.5/2)^2 x 3.14 = 4.91 x 2  = 9.82 sq.in.
3":	(3.0/2)^2 x 3.14 = 7.1 sq.in

So the single 3" system is on par with the stock system, as far as total area
goes.  If I did my math right, and there is no guarantees there.
