I love this catback. The stock exhaust had that annoying low RPM resonance when revving or driving around town. The HKS has none of that. Its actually quieter when driving normal, idling or revving. When you open it up though it sounds mean! The sound out the exhaust tip whether just at idle or while on the throttle is really aggressive. I couldn't be happier with this exhaust.
