98gt exhaust upgrade

[wade73]

i am in the market for an exhaust upgrade. as far as i can tell, the only real difference between borla, flowmaster, etc is tone and volume, as they both generate about the same hp gains. what are people doing to circumvent the 6 catalytic converters on the 4.6's? i was checking into the borla exhaust, they want close to 900 clams for a cat back system. if its from the cats back, as the name suggest, then what would be the difference in putting the borla system on rather than just changing the mufflers?

the cats are the most restrictive i would think, not necessarily the stock mufflers.
