990 Adv Exhaust

Hi all... I'm looking at different exhaust options for my 07 990. Do you need to re-pack the mufflers on all after market mufflers? I'm wondering if that is a part of the higher cost for something like Akros, etc.. I really don't want to have that added on to my maintenance items.


Thanks...

In general, repacking is needed only when you use your aftermarket exhausts without db killers, otherwise no.

Sorry, but that statement doesn't make sense...

Any muffler with packing will require repacking after a certain amount of time. Repacking a pipe is really not that big of a deal. If you have a drill, some time, a few pop rivets and a repack kit it's not a big job at all. Certain factors will determine when they will need a repack such as: conditions you're riding, mud invasion into the pipe, water invasion into the pipe, how many miles/kms you ride, etc.

So, to answer the original question, a repack is no cheaper depending on the pipe. It's pretty much the same. The only pipe I know of that is a packed pipe and doesn't ever need service is one that comes from Staintune in Austtralia. I had one on my F650GSPD and it sounded great! It's wasn't cheap though... Fwiw... Just ditch the stock cans man! They are hot, heavy pieces of steel that do not belong on such a nice bike,

Cheers!

However, with a db killer any loss of packing properties will not be audible.

Sure it will. No packing means no packing, lol! An empty can or one with ragged carbon infused torn packing is always louder than one with proper packing. Fwiw, you can extend the life of a packing job by double merely by wrapping the core (a perforated tube that is the inner "tube" of the exhaust can) in stainless wool before wrapping the actually fiberglass batting around the core. This will help prevent the fiberglass from being blown out of the exhaust when you really rip on it.

i've had a set of Leo Vince pipes on sence '08 and have had no problems at all with them

Leave the inserts in for a nice tone or take them out for some thunder in traffic.

Also they were cheper than the akros

I've had Wings and FMF's on my 990 so far and many other pipes on other bikes. The Wings are amazing, sound great, come with 2 types of db killers free and are a fraction of the cost of Akra's. Not as cheap as FMF's, but also much more versatile! Wings would be my first choice also.

I've decided on Wings. Placed the order this morning with Gorazd. I'm having them send me additional packing material and the rivets as well. What kind of interval are you guys getting before having to repack them?

Well it's nice that you will have extra packing & rivets, just remember where you put them as it will be quite some time

before you will need to use them . I don't recall anyone needing to repack a set of wings over the past 5 yrs maybe, someone

has,, don't know

Depends on how you ride... If you ever fill your pipes with water or mud riding in wetter conditions or if you spend a lot of time ripping on the throttle in wide open spaces without the db killers in it could be sooner rather than later. I generally make it a point to change or at least inspect packing every 25,000kms. That will at least give you the chance to wrap the core in stainless and get 50K out of that pack job.

Fwiw, it never hurts to have spare parts handy. If you're like me you hate waiting to fix something. I actually have a full set of spares for this bike on hand (bearings, seals, crush washers, body clips, bolts, screws, etc), but I'm a bit manic about service, lol! Congrats on the choice and enjoy!!!

*Edit: My maintenance schedule is high because of what I ride (primarily off road/gravely/dusty roads). I've already had to replace rear wheel bearings at 9000kms and I've had the bike less than 3 months, LOL! Lets hope your maintenance schedule is less!
