Like Chris said numbers are fun to talk about, but if the usable power comes in low and climbs steady, it feels faster even if your giving up a few HP, and feeling power throughout the gears is tits compared to a 3500 4500rpm high hp number, it must be the 42 years of experience...D&D makes some nice exhaust also.

Interesting test; my gut instinct says that the main difference in power was the Thrashin system being held back by the dogball resonator. It's my understanding that the resonator gets rid of the classic empty pipe "rooga rooga/hub blub blub" sound upon deceleration that your new setup now has. 🤜

Dunno if you’re aware. But Thrashin have a tailpipe without the dog balls. If this comparison should have made any sense you should have compared similar baffles. Actually it’s amazing how close the dog balls Thrashin version is to the HP one. Anyways. Love your shit! Keep at it 🤙🏼

@anthonygranato7748 Жыл бұрын

In general, the exhaust system is designed to minimize back pressure. At the same time, the pipe diameter and length are carefully balanced with the engine performance. This is done to generate the right gas flow rate that assists in engine scavenging.Basically, back pressure is a function of the length and diameter of the exhaust system. While reducing back pressure is necessary, you also want the exhaust gases to have a minimum velocity. When the exhaust valve opens a high-speed positive pressure wave exits the cylinder and drags the exhaust gases with it. This wave travels at a certain velocity, they leave a low-pressure zone behind them. The low pressure helps in creating a suction effect. As a result, evacuating the engine chamber from the burnt gases gets easier. The entire process is termed inertial scavenging.

I'd be interested in seeing the numbers for it(Bassani), in comparison to the D&D (and HPi/Thrashin). The Bassani is pretty popular pipe and I think you should include it in the shootout.
