All personal opinion of course, but I love my 2 into 2. The sound is just right. I had a hard time when I first got the Stryker because I couldn't hear what the engine was doing and without a tach, I was a loss on shift points. The new pipes changed all that improved my shift points and gas mileage (when I'm not romping it to hear the rumble). You will not be disappointed with this exhaust man and so far it is my favorite addition to an already awesome bike.
