Great dyno graph but you need another
Buying a new M8 Sport Glide adding your pipe. HD doesn't have a header for this bike and I am sure the stock pipes with HDs slip on costs power with there Stage kits. And it sounds like a Vespa scooter. Love to see there Stage 4 with there slip on vs your pipe. Would have to sell you more systems.
I would recommend this product
