Exhaust flange retaining ring upgrade

Exhaust flange retaining ring upgrade
I tried this retaining ring as an experiment when I installed my exhaust last spring, and I’m glad I did. Since then I've had the exhaust off about 4 times for various reasons and the ring is not rusted or distorted in any way. I would never suggest changing the exhaust flange retaining ring just for the purpose of upgrading it, but if you are working on the exhaust anyway, this is a real nice replacement that I would definitely categorize as an upgrade. It is a spiral, gapless, 18-8 stainless steel retaining ring, it fits the flange ID a little tighter than OEM and provides more surface area contact with the flange. It is a little thinner than the OEM ring but ultimately it is still stonger because of the material. It can be installed by hand without some type of spreader pliers, and it is priced relatively cheap at $3.00, considering its probably the last retaining ring you will need for the life of the bike. (this ring fits stock size 1 ¾” head pipes, you’ll have to look for a different ring for bigger pipes)

I also tried these flange lock nuts for the flange studs to replace the OEMs, which have proven to work excellent. $9.00 for a bag of 100. At .09 each you can afford to use a new one anytime you remove it. I’ll admit I bought some high dollar stainless nuts at the same time but I never used them, I liked the black phosphates better.

If I ever have to replace studs, I would probably spend the extra $ for stainless, but good stainless nuts are a waste at $6.00 a piece.

Too cool, somebody else finally found these usefull. I just swapped pipes again about three weeks ago, and they are still in perfect condition. not distorted at all and didn't lose their springitude, and I've been runing lean and hot enough to burn the Swain Tech ceramic off my pipes. They do make short work of swapping flanges.

I thank you for the info. I bookmarked the pages. I have had countless times frustrationed from having to R/R rusted header flange nuts and studs on my cars in my life. I will have to R/R the clutch in my 96 Mustang Cobra soon and I know it will be a bear. New SS studs or bolts and nuts are the way to go.
Thanks for the link.

Most aftermarket pipes are designed to work with OEM flanges so they don't come with new flanges, you just swap them out. I would verify if your new system comes with flanges befor letting go of the old ones. Some come with gaskets, some don't, ask the manufacturer. Either way I would still recommend trying the retaining rings mentioned in the original post, they are awesome, last set you'll have to buy, barring any crazy damage, remove and replace numerous times with no distortion and stainless so no rust.
