Yoshimura Y- Series Exhaust for the FJ-09

[morkys]

Ok, sounds good. Ordered the Yoshimura Y-Series! It is on the way I will get my torque wrench ready and look for the values. I have a rear stand I bought and used with my Honda CB500F, I will see if it works with the FJ. I have a friend or two who can lend me a helping hand.
 
I will be installing the exhaust with less than 2000 km (1250 miles)...Should I use new gaskets?

[chitown]

No. You're nowhere close to needing new gaskets. Put that many miles on with the new exhaust weekend before last
 
There's a description and photos of an exhaust removal here: https://fj-09.org/thread/2911/12-step-replace-oil-pan
 
While it's not necessary to remove either wheel removing the rear makes it easier to get to things.

[morkys]

Ok, thanks.

The Yoshimura exhaust is at the Post Office waiting patiently for me If I have at least one friend, a torque wrench and a wide open garage, how much time should it take to remove the oem and install the Yosh?
 
P.S. I asked a few of you owners some questions in messages. I guess I could have asked here.

Should not take more than 1 hour for sure, I removed my exhaust in about 20mins alone including the time it took to set up tools.

[morkys]

Fair enough. So 14 LBS/FT or 20 NM is good for the exhaust header bolts?

[kingofthenorth]

Yep 20NM for headers nuts and the 2 bolts near the center stand.
Put the bike on side stand and just drop the center stand when you need to make the « twist » move (you will understand)
 
My bike has 16000kms and I did not need to replace gaskets.

Should I use new gaskets?

always. They are crush washers and by definition are single-use only. You don't replace them because of mileage (or lack) but because when you install it indents the mating surface and you're not going to exactly match up the new exhaust to the previous indentations. 
It's a trifling amount ($13?) so having shelled out $6-800 for an exhaust it's just beyond silly not to do the job completely and correctly. If you want to save money, skip the next 3 Starbucks coffees and you're back to break-even.
 

[kingofthenorth]

Sorry about my misinformation, I agree that if it is a different headers going back there, new gaskets.
 
I guess I did not need to replace because I used the same headers/shape and it went back in same spot.

[chitown]

Yes, the manual calls for replacement and can't fault anybody for following that policy. Replaced mine because they needed replacing. But have also inspected and reused. Will continue to use my judgment on certain items a mfg might declare single use. Will also ignore the shift points in the manual, the chain slack spec, and some of the wild and whacky errata found in manuals over these many years

My contribution to the Yoshimura exhaust thread. Figured I have asked enough questions, it's time to contribute something. Yeah, I know it's not the lastest news, but it's experience just the same. Here is the beast being slid into my trunk. it arrived here in Pickering, a burb of Toronto, all the way from BC via Canada Post in less than a week. Gotta hand it to Canada Post, they ain't no slouch. I love picking up a Yoshimura exhaust from the Shoppers Drug Mart Post Office...lol.
 

 
 
 

 
 
 

 
 
My best weight of 3 tries with a bathroom scale reports 12.6 LBS. Going to pick up three exhaust manifold gaskets on my way home from work today and set aside the few tools I need including torque wrench, then clear space in the garage. Hopefully with a friend this should be short work. I don't have any mineral spirits so I may just wipe it down with a cloth damp with iosopropyl alcohol before throwing it on the bike and starting it up. I will try to take a video of the exhaust in action after install.

spray the current studs/nuts with penetrating oil and leave overnight. It's not uncommon for them to corrode and end up coming out of teh engine block instead of the nuts coming off.

[kingofthenorth]

Forget about bubble wrap, Spray foam!

I will give a spray if I can find some. My FJ is less than 1600 km in and barely 7 months old stored in my garage over winter.

I think this is good advice, but wasn't required for my install (Akropovic)... some advice I have is, dont over torque the nuts onto the stud.. they will bend.
