[QUOTE="99SVTcobraVERT, post: 135514, member: 1630"] haha its ok about the questions. ok here goes. h-pipe give you more the old sound 5.0 style like the old built cars. the x pipe is more like a italian car with exhaust because of our cars unusual ability to reach 7200rpm. the best sound set up i can advise is either a bassani hi flow x pipe with fr500, or x with flows. also bassani makes a good cat back also,but doesnt bring the power that the fr500 does. and my rwhp isnt all that great for what i have. i think his new motor that i got wasnt quite the kick the older one was but i cant prove that because i neve dyno that motor. i have mac cold air, fr500 exhaust that dyno was with the offroad prochamber pipe so that may by why. they say its best to use the hi flow x when using the fr500. the car did 273rwhp and 276rwtq stock. and after all mods on motor it brought 292rwhp and 301rwtq. so with average #'s 13rwhp cat back,15-20rwhp pipe, and 5-10rwhp intake. so it should have net 33-38rwhp more. so i only got 19rwhp more. so i think its the offroad pipe not giving enough back pressue but my torque didnt suffe much. but im very happy with torque #. from talking to everyone i would prob pick up closer to my torque # in rwhp if i put back on the bassani to work in harmony with the fr500 because they are designed with same type of X. and corking the motor?? if you mean what were my cool down times, it was about 5 mins per run. not very long because i was in a hurry and wanted a quick 4 pulls. 2 na, 2 nitrous. first na was high hp but i had a hickup in the torque early on? didnt happen again 2nd pull. first run nitrous yeilded almost 1200psi bottle pressure. 2nd run had more 18more hp but like 25 lbft less torque. and as far as safer...i have had 3 sc' cobra's and 1 nitrous cobra.
