yet another exhaust question

[redlinedeath]

ive read all the other exhaust threads and to my understanding, i DONT need a cross pipe, and can run true duals? my main concern is makeing a bit of power, without the car sounding horrible, and i do want a nice sounding exhaust(but will sacrificea bit of sound if need be). im also concerned about the weight, as it is a 94 ls-i, would there be better weight reduction just running manifolds to resonators, to 2-into-1 high flow cat then piping back to a muffler, or stick another resonator in there after the cat, as opposed to true duals? like i said, weight and power are my main concerns, and do plan on doing headers in the spring. for now, ill be doing n/a maybe turbo a different motor in the summer,not sure, but if thats the case, it will be a slow build, a little here, a little there. any info would be great. thanks!
