What is the Purpose of a Loop in the Exhaust? Honda Grom Zoom loop exhaust

[@mb4lunch]

Not many tuners have figured this stuff out. Kudos to you sir.

[@0to60eventually_youtube]

The science is deepAF - hats off the all the real tunners out there.. and thanks to the good quality “bolt on” companies that figure it out and sale us the good stuff

[@achraf9946]

The Wisdom you share with us for free thank you sir!

[@0to60eventually_youtube]

My pleasure!

[@laegers]

Love your grom videos, keep them coming.

[@0to60eventually_youtube]

I have a bunch more grom goodness coming soon! 😁

I believe what happens is once your exhaust gas is back in the atmosphere, it has drops of Jupiter in its hair.

[@0to60eventually_youtube]

Nice… 90s throw back.

[@ryanrivard8775]

change intake or exhaust = need tuned ecu for each set up for best ppower

[@0to60eventually_youtube]

Intake = ecu reset (no flash/tune) InTake + slip on = ecu reset (no flash/tune) Full exhaust + intake = flash/tune and ecu reset

Very interesting to see an analytical approach to your motorcycle's performance instead of relying on urban myths like the rest of us. I just bought a pristine 2015 Ducati Scrambler with no mods whatsoever and the first thing my biker buddies asked was... are you getting a termignoni? And while I would like to get one eventually directly from Ducati (with cat) so it's legal and passes Swiss periodic technical inspections, it's not a priority. Stickier tyres, assuring proper maintenance and mostly riding the thing are my priorities. A loud exhaust is not! I've been dreaming of owning a motorcycle since I was 12 and I'm 46 now. I'll have time to tinker later. Great video! Definitely subscribing!

[@0to60eventually_youtube]

Thanks, I agree, it's all about the riding. Glad you're enjoying the video!

[@bena4316]

Wow, this was recommended to me by KZbin! Such a cool video

[@0to60eventually_youtube]

Thanks, glad you enjoyed it!

[@edwardcampbell3420]

Were talking reversion wave. Big thing on Harleys. Have you tried no restriction exhaust with a washer set back one inch from end of exhaust. Aka lollypop.

[@ryanrivard8775]

humm long tube headers are good...wow

[@mb4lunch]

I race WERA and work with a guy that knows these things. It's all true. You have to tune it for torque where you want it.

[@0to60eventually_youtube]

The science is deepAF .. hats of to the real runners out there

[@joekavalauskas8767]

I installed a Decha stealth air intake tube and drilled some holes in my air box, a good noise and plenty of oxygen. I tried an eBay exhaust and it was too loud even with the baffle. I'm keeping the stock exhaust on. It allows me to fit a Kitaco skid plate as well. I really want the zoom loop pipe but allow me to put on my own slip on.

[@0to60eventually_youtube]

Yep, I can relate. I found a slip on pipe along time ago, allowing to leave stock header pipe, which is tuned well for the engine. Air intake, slip on would allow to run it with no tune.. that plus one less tooth on the front is a nice bang for the buck..

[@fidelramen5202]

How did you get the length of the header pipe?

[@0to60eventually_youtube]

Just purchased the pipe, had DHM tune the ecu for a “yoshimira loop pipe” and started trial and error. The way to load exhaust kept me going back in with the Db killers … and got lucky over time

[@0to60eventually_youtube]

To be honest a slip on with a tune would probably be the best balance between sound and power access

[@yelnatsnart]

what rack is that?

[@0to60eventually_youtube]

Not sure, it was on it when I bought it

[@hogueraleksander5868]

Cool looking grom. I still dont understand why anyone would buy one and not a real motorcycle. Maybe is the wheely thing?

[@0to60eventually_youtube]

It’s a weird human behavior for sure. 4k pulse 2k in mods to go slower than a R3 or a Honda rebel 🤣. Short answer is if mopeds are fun, then these are even more fun… when you get into 300’s or bigger you have to get more responsible… 😎😂

[@hogueraleksander5868]

@0to60eventually_youtube I guess people see them as a bicycle and dont even wear a helmet.. who knows. I started ridding motorcycles 6 years ago. I had 3 cars and figured maybe I get a scooter for short 10 minute trips and to avoid paying for parking. Then I saw shitty 50cc scooters.. then I'm like, I could never buy that. Then saw 125cc and they barely do 35mph... then some 200cc. Meh. And then I said, for the same price I can get an 1100cc bike and turn it into a bobber and actually own something cool. So 10 motorcycles later, I still don't have a scooter lol.

[@carlangelo653]

You can get away with doing a lot of dumb stuff unscathed while on a smaller bike. Stuff that will get you killed on a bigger bike.

[@okok-oc4ko]

If can't get these bikes up to 100mph, you can't crash these bikes at 100mph.

[@hogueraleksander5868]

You can easily die at 50mph if you are unlucky 😅. Technically if your head hits the cement floor with no helmet at 3-4 feet, you can meet your maker. Always wear protection, even on a scooter.
