Exhaust Question..

[mustangmach04]

Im going with Dr.gas x with a mac catback on the mach. What size exhaust should i get, 2.5 or 3" ?? I will be getting kooks long tubes when i move in a few months to florida(west palm)

I could be wrong but unless you have a blower you want 2.5". Gives you a more back pressure which helps the low end torque.

*NOTE* I have not researched this point since the April of 2003 when my Mach was only 5 months old.

2.5 inch. Cobras pushing 460rwhp dont even need 3 inch. Im telling you, 4V's need a little backpressure to be street worthy.
