We are back at testing out exhaust pipes and cams on our shop 2021 Harley Low Rider S.
The S&S Cycle 475 Cam is by far one of the most popular and one of the best performing cams. We started with that and paired it with the SP Concepts Lanesplitter exhaust. More air is always crucial for better performance, so we also upgraded to the HPI Tunnel Ram with 58mm throttle body.
Check out the photos and video below for a sound clip and Dyno chart.
We were really happy with how to the SP Concepts Lanesplitter exhaust performed. Most 2-1 pipes have a hard time putting out good numbers and the Dyno Tq/Hp curves can be very disappointing. But this one performed really well, check it out for yourself!
