This is the third cat-back I have tried and by far my favorite. Combined with the JDL UEL catted header and 3" catted combo-pipe, this system sounds amazing. Yes, the cold start is brutal, but once it warms it is surprisingly quiet inside. Unlike the other name brand systems I've tried, this system is very mild mannered when just cruising around town enabling you to have a conversation in the car with ease. But then when you get on it, it screams! All of this with no drone, what more could a girl ask for! Very pleased with this purchase!!! <3
