These "tech" vids are the best. Sick's explanations and experience deserve to be continuously HEARD.
Great garage Block, enjoy being here.

Anybody that likes to do their own work has to love you guys. Great information for all of us. Appreciate the work you do to help keep us informed.

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.

I love the way you work. You are experts on doing what you are doing. But mostly I love the way you get along with each other. Keep up the great work, performance, friends and great vives at work. You all guys are pros.

I’m actually anxious to see the D&D pipe numbers. I so appreciate the science research your doing 😁.

[DoctorMotorcycle]

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. 🤜

[stevewilliams]

Thanks for all the hard work you have done to show the difference in each pipe. Mine is on order with you and waiting on delivery for my 24 Low Rider ST

[bowlingmatt]

What about a thunderheader? I love the sound and performance on my old evo.

[austinap]

Iv'e got the mid length stainless steel 2 in one Bassani on my 2020 SGS and it's awesome.

[williamb.]

I'm looking forward to the D&D pulls. I'm also interested in the Sawicki. Thanks boyz!

The only problem I see with HPI is the lead time. They're like 16-20 weeks out. I think they are the best but damn 16-20 week wait and +$300 for 3 or 4 horsepower? Is it worth it? Your call.

[anthonygranato]

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'm in California and I'm amazed at how far the grumble is with this pipe it pumps louder than I thought it would be allowed to

[zaytona]

Súper dope exhaust. Can’t wait to work with you guys really soon. Great groups of guys with a lot of experience.

[matt_wrx]

Baffles me how expensive headers are for bikes…… flat out ridiculous compared to cars

[ValOzuna]

Dude I would love this bike in my garage. I bought a 2020 fatboy with the M8 but I shoukdve bought the lowrider st. Absolutely love this bike. Thanks for the video!!

[이재학-sp]

Riding, motor cycle life~ 🌞
If you raise your hand, 👋, it's even more nice to meet you. It's safer. It's more honest.
Always be happy with you.👏👏

[slayer]

Cam and exhaust shoot out!! Please for Science!! I would love to know what Woods cam 22xe vs 22xd does?!! Love the HPI sounds a lot better

[michaelmitchell]

For sub 2 grand for a pipe, it better perform..., so in other words their both great exhausts for the m8, but stupid expensive...I'll stick with my bassani stainless 2 into 1. Great video tho guys, love what you all are doing.

[jakeb.]

Love the Thrashin pipe but the HPI does look damn good on the ST
