besides the fact that one has more top end power then the other. Are the hp gains pretty much the same, because i was leaning toward a single exhaust possibly JIC or DC or Tanabe any opinons on these exhausts?

 

Many options no offense but search(sound clips) to be able to hear they are all pretty close, from my experience with custom dual is you lose t/q low but gain hp up high if that helps. My set up is lame but I raced 2 05's this weekend touring and track pulled both but it was 3rd gear that started pulling on them. It was a rush when I pulled up they were like looks nice but sounds ricey...then they liked it after the races man I was proud...even though they werent broke in well the track had 1200 miles on it but the touring only had 800.

 

were they both stock..? I'd hope you could pull a stock Z with your mods

 

Say the car has a single pipe and canister it will have low to mid range torque, but lose high end torque right? Then if the same car has true duals with 2 canisters it will have mid to top range torque, but loses low end torque right? Now what if the same car had true duals from the cats but it came into a single canister, what is the end results? What exhaust system on the market would give you the best range of torque without scarificing 1 or the other or would you have to scarifice 1? TIA
