i just resently installed a magna flow true dual exhaust on my car
sound really good outside the car but on the inside the drone is sometimes js horrible
if i put some dynomax material in tha trunk will that help keep the cabin area noise down

 

...doubtful

 

The drone inside the car is the only thing that keeps me from getting the magnaflow catback. I've searched here for ways or ideas to silence it inside but I came to the conclusion that the only way is to quiet the exhaust itself down...
This is one of the threads with some information on this topic.

 

You indicated a true dual exhaust. I assume that means you installed something other than a Magnaflow 16633 catback, which is not dual. It's just dual mufflers on a single exhaust. I hear some minor possible drone with the 16633, but generally love the sound. What did you acually install?

 

i just posted an update to my thread about the sound deadner check it out
