I got a new bike today it's a 2016 Harley Davidson roadster 1200cc sportster style motor perfect for my commute to work fast enough to get me out of trouble when need be
Yea It's about exhaust flow the 2 into 1 systems provide less restrictions when combined with a proper intake system and tuning the power gains aren't crazy drastic but worth the $
@Bungler not exactly but it was intended for individuals of smaller physical stature but it's perfectly suited for me to zip around and get to and from work.
