Downpipe nuts backing out

[92gsxbafaro]

Just like the title says I just got a new exhaust on my gsx and the nuts that connect the downpipe are backing out. My question is will red locktight be enough to hold them on?

Red will work but might be a bit too much, use blue as its more vibration and heat proof also stick some locking washers on that will also help them stay on

If you don't have lock washers, do that either way.

Loctite 266 red-orange, high temp resistant.

The lock washers helped for me,stopped the nuts from backing up

Gotta love an easy fix.

The nuts from the DP to the O2 housing?

Use a copper based anti-sieze lubricant and hot torque the bolts. (do a couple hard pulls and then torque them right away) You have to do the same thing when you plan on loosening them later on though...

I have never had an exhaust fastener come loose again after doing using that procedure. And I have never had a stripped, broken or corroded exhaust fastener using the copper based anti-sieze. It works better than the graphite based IMO.

If you are still having the problem of the nuts backing out, get yourself another nut for each stud and double them up. Just don't over torque them. Had the same problem and ended up taking the bolts out and going v-band.

What is so hard about buying the OEM nut and using it. They are not simple nuts, they are lock nuts and they do have a finite life. Lockwashers won't last under exhaust heat, they lose their spring. It's not a serious enough connection to warrant locktite. 200k miles and I don't know how many times I've had a down pipe off but I never had one back off. I also replaced the downpipe nuts periodically with new OEM nuts.

They are still backing out im going to try the copper based thread lock and new nuts now

I had,a problem with this and used lock washers to fix. So far so good but after oem nuts, would work best.

 

[92gsxbafaro]

Where can I get oem nuts and lock washers?

 

[pauleyman]

OEm nuts do not use lock washers. OEM....well that implies at the dealer or any mitsu retailer vedor.
