From what I've read, even Staintune exhausts need repacking. Their big thing is that they don't use rivets, but bolt the innards to he end caps. Sounds like a quality system but I've read about people repacking them.
My shop is the importer and distributor for stainitune, trust me, no repacking
The packing burns out. OEM exhausts don't have packing they have baffles.
Twins tend to be harder on the packing. The Muzzy on my SV650 is so loud it is embarassing. Packing just arrived, I will repack it next week.
The manufacturers I looked up recommend every 6-10k miles...ouch!

hitman5532 : It depends on the manufacture. Some (like staintune) never have to be repacked, and are welded shut even.
when I ask them .There is never a need to internally service or repack a stainless steel muffler because the packing material is a spun stainless steel wool. It will not disintegrate or blow out, ever. There are no rivets and there is no way to open the muffler up to get to the internals.
Yeah I have Staintunes on the ST2 and it's been past that time . The problem is ... Munroes's is the only one that has the kit , so I gotta go to the city , but every BMW dealer just goeswhen I ask them .

For those of you with an aftermarket exhaust, how often do you repack it? The manufacturers I looked up recommend every 6-10k miles...ouch!

But my packing is so full of soot and burnt oil, I think it's probably quieter than it used to be.![]()
