Exhaust systems?
 

I got a 2001 GT and i waana hook up a new exhaust. I was looking at MAC catback, but i also saw a Ford Racing exhaust.

Is Ford Racing a good choice to get some real power? or should i just go with MAC?

Basically i want to go as fast as possible down the quarter mile. which system would best help me while im N/A?

A cat-back system does nada\zip\zilch for horsepower on a near stock vehicle...

As far as sound goes, I like the Dynomax, MAC, and Borla systems...
