Borla exhaust anybody?
LOL at the ultra flows being quiet. You may have listened to the normal Dynomax but you have not listened to the Ultra Flows.
We already did a thread on this. The Ultra Flows are just about the loudest and best flowing you will find.
How loud are they? I run them with stock 340 manifolds, and full TTI 2.5" exhaust. At the track my car was to loud and I was forced to make a sound pass for the track police.
