However, with the valves closed it chokes the exhaust flow. Comparing the NPP exhaust with valves open to our Valvetronic Maxflo Exhaust with valves open, we saw peak gains of 4 whp and 6 ft\/lbs of TQ.\u003cstrong\u003e \u003c\/strong\u003eComparing the two in valves closed mode, measured at the wheels we saw peak gains of 11.5 hp and 10ft\/lbs of TQ,\u003cstrong\u003e \u003c\/strong\u003eand curve gains as much as 14 hp and 15 ft\/lbs of TQ\u003cstrong\u003e. \u003c\/strong\u003eSo whether you're in the comfortable valves closed mode or ripping around valves open, our Valvetronic Maxflo Exhaust System flows well and makes great power.
