Hey everyone, I hopped on here to try and identify this part on my 2004 Frontier. Pics attached. I'm looking at the metal weave cylinder around one of the exhaust pipes. This cylinder is on the exhaust pipe coming off the right side of the V6 engine before it merges into the other exhaust pipe and into the catalytic converter. In the pic, you can see there are two loose rings on either side. The rings are clanking whenever the engine is running, but don't appear to have actually been doing much in the first place. I believe this is just a heat shield and the rings are clamps, but not positive. If it is a heat shield, I'm thinking of just using some high heat epoxy to reattached them. Thoughts?

The weave thing is a flex pipe. It allows for movement of the engine separate from the exhaust to not break any welds.

As for the rings, I have no idea. Is there a hanger anywhere near them that may have broke? Is the exhaust stock? If everything is fine, I'd probably just cut them off.

Also, Welcome to the forum!

Thanks for the welcome Chris! I believe the exhaust is stock, but I am the 2nd owner. From their diameter and taper, they appear to have been on the ends of the flex pipe, but a bit higher up than where the flex pipe actually meets the exhaust pipe.

Those rings are the end caps/rings of the flex pipe. They are there to keep the woven part from fraying.

When mine came loose like that, I cut them off and never had any more problems

not epoxy.... JB Weld may be an option, but I'd start saving for an exhaust shop to replace the flexpipe. All they do is cut it out & weld a new one back in. Cost should be between $100-$250 depending on price of flex and how much they charge (gouge) hourly. Time-wise it will be an hour or less (so most shops will just charge a full hour for first hour). I had to have my car done recently.

JB weld will stink for weeks as it burns off, then the pieces wall fall off again - tried it

Those caps don't really help structurally with the flex pipe and if the pipe leaks after cutting them off then I think it would be for other reasons, just my opinion

I can't tell you how many of them I cut off while working for Nissan! Just cut it off, trash it and forget about it! It'll be fine without them.

Mine broke off mine before I got had a custom y pipe made. Just cut em off, really no need for em
