I would say Borla because of the options you have with the interchangable plates for sound and performance. On the other hand, from what I've heard, the Borla doesn't fit very good for the thirdgen. My Flowmaster bolted up very nicely and was alot cheaper. I personally wouldn't pay the extra money for the Borla system, even if it is stainless. The Flowmaster has a great sound to it and I haven't had any problems with it at all for over 1.5 yrs.

Flowmaster, Borlas catback systems are about 6 inches shorter, sure there stainless steel and are interchangable but if u pay $500.00 for a catback ur out of your damn mind, Flowmasters catback provide decent flow, nice aggresive sound, fits as factory u pay $250.00 and with the extra $250.00 u could buy something else, my opinion go with the flowmaster

 

if you have the money borla..if you really got the money SLP

If you thinking about Borla, you might want to try going with a 4th gen Corsa system and just adapting it.
