Love my Akra Evo from EAS. Best mod ever. It is a lot louder than stock but not as loud as some competitor systems.
When I first purchased the system (my first exhaust ever), I initially regretted the decision based on the increased volume. After a few weeks I fell in love with the sound and just love the aggressiveness.
You do attract attention with it but it is manageable with gentle acceleration. Garages/tunnels/underpasses are now my favorite places to enjoy the Akra
Also you can't beat its quality construction--truly a work of art and weight savings too.
