I have had these on the bike for about 2 weeks. Product quality is top notch, Installation about 1 hour.. These pipes have a drop in low end and midrange without the optional P1 X inserts. Plus I don't need a tech inspection rejection by TA and WC.
With the P1X inserts Performance is close to stock in the low and midange after that the pull is increased. You feel the increase for sure but the benefits do not stop there. You IBR / LDR brothers will Freak over the increased MPG, I noted 44+ mpg at 75-sub 90 mph on the slab at 98 degrees and elevations of 350 to 1200 feet. Still some testing to do .
