Sorry if this isn't the place to post this but im new and i was wondering which was louder on a 2011 infinti g37 coupe, a muffler delete or the topspeed axelback exhaust. Im on a budget and im in college. Anyone with any information would be a big help, thanks

 

This really should be in the Intake/Exhaust forum. Take a look in there. Also, both the Sedan and Coupe forums have pinned threads dealing with exhausts specific to each body style.

 

A muffler delete will for sure be louder than an axle back exhaust. You can find tons of opinions and youtube videos scattered throughout the forums. As stated above.

 

The non-resonated topspeed axleback is literally a polished muffler delete.

Resonated axleback is much quieter and IMO gives a subtle purr whereas a delete gives a loud growl
