Neither. Its great. I had a paul turner hi rev with kens head mod and ported cylinder and I loved the exhaust but it gave me power at the mid to top.of the powerband and It didnt really suit my riding needs. but I say hell yes, run it
Same pipe as a power pro's, ct racing, Factory7, and a few others... i like the power output of my right bend, but the sealing quality was garbage had to use too much RTV.
