I dont know if you'd consider this a sleeper but all the c5 vettes and camaro ss' always think I'm joking if I ask them to line them up...Most are pretty surpised by the outcome, 100% stock exterior other than wider than stock rear tires(still on the stock turbines) Blower is nearly silent...pretty tame until you get on it. ran a 12.7@107 with my **** driving. daily driven without a problem, here are a couple pics
