The video compares a Dominar 400 with a stock exhaust and one fitted with a Paolucci exhaust system. The Dominar 400 is Bajaj’s flagship motorcycle and has been updated in 2019, with various new features. Some of the new features of the Dominar 400 UG are USD forks, gear shift indicator, new aluminium cast mirrors, etc. But in this video, we see the previous version of the Dominar 400 on the dyno run.
The Dominar 400 comes with a 373.3cc, single-cylinder, FI engine that produces 34.5 HP of power and 35 Nm of torque. The engine comes mated to a 6-speed gearbox. The stock bike has a top speed of 148 km/hr. The technicians at Paolucci Racing Performance replaced the stock exhaust system with their own racing exhaust system, which was finished in a nice chrome paint, giving it a very premium and sporty feel to it. The aftermarket exhaust also had a very raw, throaty and powerful grunt to it, and as the revs got higher, so did the grunt from the exhaust.
The Dominar on the dyno run, with the full exhaust set-up from Paolucci, showed a maximum power difference of 1.74 HP at 8486 RPM and maximum torque difference of 0.15 Nm at 7993 RPM. This full exhaust kit for the Dominar is 6 kgs lighter than the stock exhaust, with the stock exhaust weighing in at 10 kgs, the Paolucci exhaust weighs only 4 kgs.
