well i just got a camaro and the guy before me put real duals on it they dont look in the best of shap they r covered in cerfus rust but no holes or exhaust leaks. anyway i got a new 3" catback with free a freeflow cat and flowmaster muffler with dual tips. does true duals make a diffrence?? or could i put this on and loose no power??

 

You may not necessarily lose power going to a single 3" depending on how your dual setup is routed, but personally I have yet to hear a single exhaust setup that sounds better than a comparable dual setup.
