Exhaust packing-2007 CRF450

My nephew just picked up an '07 CRF450 and the pipe gets red hot as it exits the engine very quickly. We are going over some stuff and pulled the muffler cap and do not see any exhaust packing, just the spark arrestor cone. Not sure that has anything to do with the heat issue and can't find anything online so thought I would ask if anyone here has any input.

Thanks!

500 EXC muffler question

Fri, 18 Jan 2019 02:59:18 +0000

Been poking around and planning the changes that I need to do on the Orange bike. Saving up for the Vortex and plan to do the smog delete and reed valve removal (only about 100 miles on the bike and already hate the flame outs!). Looking at end cap replacements (like this one: https://www.ktmandhusky.com/exhaust-upgrades-for-2017-exc-fe) instead of a complete new muffler; waddya guys think? Seems the stock box is okay but the restrictions inside are less than desirable. If these work like presented and I can keep the stock appearance (to avoid ranger danger) it sounds interesting.

FMF "turndown?"

Wed, 07 Feb 2018 15:28:36 +0000

Learning all the time, mostly from SDAR moto folks. FMF no longer makes a muffler for my 2007 bike. An attempt to fix is the next step since the high heat gasket maker red bonding attempt only lasted a couple months. Apparently, in interior piece called a turndown has come loose. I do not know whats inside so I do not know where it became unattached. FMF rep strongly thinks that a previous owner repacked incorrectly and broke it. Consequently, the end of the spark arrestor vibrates in and out of the muffler up to 5/8 of an inch. Doesn't seem to be a big deal, have ridden it like that for awhile, but it would be nice to fix if possible. Maybe a more serious Bonding agent? Maybe a repack, and while in there, a small tack weld inside? or a tiny tack weld from the back with spark arrestor out? But, titanium is the name of the muffler, so is it actually titanium, and can it be welded easily? I would need to slide the spark arrestor in still after the weld so there isn't much room to have a bubble in the weld that restricts the insertion of the spark arrestor. I attached a pic with the spark arrestor out, and pliers holding the part apparently called a "turndown" that slides in and out a bit somewhat randomly. The pic shows where the spark arrestor screws in with a small allen bolt, not to the exterior of the muffler, but to the turndown. Any thoughts? Thanks.
