The Nameless exhaust is NOT quiet, especially if you go with the muffler delete. How loud are you trying to go? Even the 5" Nameless muffler drones like crazy.

I'm running the STI muffler from Japan. Great tone, OEM volume, looks AMAZING.

 

I loved my muffler delete, but it was just too droney.

Been looking at maybe trying out a Flowmaster FlowFx muffler.

 

Honestly, you get what you pay for. I love my syms muffler as a starting point. But it's expensive. I've spent over 4k on my header back exhaust without labor, and the few fixes I need to pay a shop to do.

I have the Nameless with the 5 inch muffler, I agree its a little quiet but I wish it didn't drone as much as it does. I just think it's a fault of this platform though.

 

Went with the SYMs and absolutely love it. No drone and loud enough to enjoy without being annoying.
