2013 camaro brochoure specs for 0-60 for the 1le is listed as 4.7 sec same as 2ss ls3, and anyone with a half of a brain knows with higher rear end ratio of 3.91 , 0-60 has to be quicker than 4.7 as listed by chevy. In fact motortrend test of the 1le 0-60 time was 4.3. So just because chevy says theres no difference in hp between the duel exhaust and stock exhaust they might be wrong.
