that sounds awesome, now that is regular 40 series, not the delta flow right?

 

Thank You ....that is a delta flow.... The shop put a 3" after the cat so its a true 3" cat back exhaust....

 

what exactly is a cat back, when you have exhaust replaced from and including the 'cat back' ? And I don't think mine sounds like yours lol, although I've never really listened to it with a camera like that. And mine is dual, but idk how that would affect it.

 

the norm cat back would be after the cat maybe a foot after it then the custom exhaust. to what ever your like... why it sounds like the way it does ? i have no idea ....cause under the hood is all stock. even the air filter .. which im gonna put on AEM brute maybe a little louder ? ill take pics under the truck , maybe tomorrow....

 

oh then in that case, ive got a cat back system. seems like most would be cat back in that case (going from stock to duals at least).
