nice but i dont see a point in getting a gt exhaust then swapping out the mufflers. seems like a huge waste of money, and a 1 back and 2 steps forward kinda deal.
i wanted to do a sick ass exhaust on my tbird, but to pass smog, it would need 3 cats, so i went to my local shop, and they told me 400 bucks for true dual 2.5", using a dodge ram 2-2 center catalytic converter(2 in 2 out style) and 2 high flow cats, and flowmasters.
i say look around, i think you can find a better way than dropping all that for a stock gt exhaust, then more for mufflers, when some shop can prolly do it for 30% less in the end.
