Muffler clamp replacement


Recommended Posts

Hi everyone:

Going to be tackling a spark plug change in the near future. Bought all the required parts and was ready to start by removing the mufflers to make it easier....and.....it seems that I can't get the muffler clamps off either side! They are rusted pretty bad. Totally ruined the momentum. The car is a 2000 C4.

I wanted to order new clamps from Pelican(?). They seem somewhat expensive but I guess what isn't. The model number I believe is 996-111-220-01.

My real question is aside from drowning the bolts in lubricating oil, it is safe to use a propane torch on them? Any other technique?

Thanks!

Using a cut-off wheel with a 3" metal cutting disc will make short work of the rusted clamps, even if the bolts have "become one" with the nuts.

Here is one from Harbor Freight: http://www.harborfreight.com/3-inch-high-speed-air-cutter-47077.html

Just make sure to wear eye protection and position the tool so the sparks are flying away from you and not towards any gas lines, etc...

Also, be careful to only cut through the bolts and/or the clamps, and not the exhaust pipes themselves. It works pretty quickly.

Regards, Maurice.

Generally it's just the nuts and bolts that are the problem and not the entire clamp. If you carefully cut off the nuts you can replace them with stainless steel nuts and bolts from Ace Hardware or other local source. They don't have to match the OEM exactly. They just need to be roughly the same size.

I assume you're talking about the cat sleeve clamps rather than the muffler clamps which connect to the tips, but the same is true for the both.
