Hey guys...great news! im back in a vette again after about 2 months without it. i am now the owner of a black 2004 Z06. and i couldnt believe the power difference between it and my 99 coupe. its absolutely rediculous. The Z is crazy fast. almost retarded fast. and i have a question. It sounds good now, but if i leave the stock TI exhaust on it and run with no cats, will it sound good and be quite a bit louder? i like the way the stock exhaust sounds alot....i just need it to be louder. any suggestions?
