Exhaust Port Gaskets / Yoshimura R77

[roadczar]

Question for people who installed Yosh R77 on the K8.
Yosh instruction state not to install the exhaust port gaskets when installing R77. I've installed plenty of systems and this is a first for me.

Did you use gaskets?
If not then did you have any problems with exhaust leaks?
Thanks.

 

[Dobieman]

You dont need them, follow the instructions. Yosh knows what they are doing.
Mine are fine and I havent seen a single problem from this.

 

[kreator]

did not use them and mine seem fine.. I was suprised at what a quality product the yoshi's are.

 

[Warchild]

Trust me, they are not needed whatsoever. The benefits of procuring a high quality, finely-machined system like the Yosh setup.

Thanks!

Still it seems weird that for '99 "“ "˜07

As everyone else has already stated no gaskets needed.

Your bike is my wallpaper at work right now...

Nice no gaskets! Dealer wanted $36 for them!

This is the answer I received from Yosh tech support..... Not pleased... This is a bogus reason for not using gaskets

That is kind of a crap answer. I got the same thing about the exhaust my self. They could come up with some FAQs on their website to make it easier for everyone.

 

[BIKE DUDE]

No gaskets!
No leaks!

 

[BusaWizard]

No gaskets here either.

 

[Italian Trev]

You dont need them, follow the instructions. Yosh knows what they are doing.
Mine are fine and I havent seen a single problem from this.

+1

 

[ks-waterbug]

No exhaust leaks on mine either.....

 

[roadczar]

I finally have mine mounted. Keeping the fingers crossed.

 

[BusaWizard]

You'll be fine. Trust the force.

I Just installed the R77 full exhaust on my Hayabusa 2011 but i forgot to remove said Gaskets, so is there is any problem may occurs in the future by leaving said OEM gaskets or i have to take them off and reinstall the exhaust ?
