I AM INTERESTED IN THE MAC C-BACK, BUT I GOT SOME QUESTIONS IF ANY BODY CAN HELP. I LIKE THE 3" BUT DOSE ANYBODY KNOW IF THE 3" WILL LOSE OR MAKE LESS HORSE POWER + TORQ. THEN THE 2.5" TO LACK OF PRESSURE. (THE COBRA IS STOCK) ALSO THE NON CATTED MID PIPE IS THERE ANY CONS TO THE LOSS OF THE CATS BESIDES CHECK LIGHT(BAD GAS MILES,FLOODING) ANY INFO WOULD BE GREAT:shrug:
