Does anybody know what the torque values are for exhaust flanges on 2018 Street Glide?

 

Are you reinstalling or replacing the full exhaust system? If so, you do know there's a sequence to tightening and torquing the fasteners, right? I'd tell you what it says for the exhaust on my '14 Limited, but I don't think it's the same as an '18 SG.

 

I'm reinstalling decated exhaust, I know there is a sequence but can't find torque values anywhere, I appreciate any help...

 

Here are the instructions for installing a Screamin' Eagle exhaust system with sequence and torque values:

Those instructions are not for a M8 bike..while the specs for head pipe flange nuts are about the same , Final Torque 100-120 inch

 

Torq charts are going to give you a value for shank dia.
That will not work as you are going into aluminum threads.
You want Snug and a fudge, check them a couple times later.

 

It came from this system which shows to fit the OP's bike:

Thanks guys!
I appreciate the knowledge.

 

The instructions are incorrect for OP's bike. But he got the info requested

 

You are correct. but. the stock M8 touring bikes do not use Item #11, looks like the Hiflow system has that gasket like the twin cams had. No harm, I would feel bad if someone drove all the way into town cause he was missing that gasket and then racked his brains and knuckles trying to fit what was never meant to be.....Good Times
