SLP center exhaust questions

i was wondering if i bought a tsp rumbler catback if it would fit with the stock z28 package, or would it be better to go with an aftermarket muffler, i want the most power, best flowing set up possible with this feature since it looks great (going to chrome the tips) and no one has seen or has one around here, ive got a welder and all at the house so, what are my otions?
