You don't.

The Cobra pipes are fairly loud to start with. Whatever they have as baffles should be left as is.

I have to agree with KM on this one ,Cobras are loud from the factory.I actually took the baffles out of mine and wrapped them with muffler packing and I like it a lot better now.

If you must remove them there are bolts on the back side of the pipe that thread into the baffle.If you do take them out Lay the baffles aside with the bolts and take a ride at high way speed for about an hour and you will come home and put them back.

My advice ? Is to keep your stock exhaust. If you want louder, remove the "goats belly" but install a cross over pipe.

Better? For what?

Louder? See above.

Rejet? No. Unless you really want to..

ok so i decided to keep my stock pipes. i have found out the PO did rejet the Vulcan to much too big and thats why is feels funky in first and second gear..so i have to get that done correctly..and also found out the PO drilled holes in the baffels..my new question is if i take out the baffels completely will i have to rejet the bike? and will taking them out affect my performance? and from the previous answers to my previous post (knifemaker) i do kow what a crossover pipe is and where it would be located but why do i need one or do i have to have a cross over pipe?

Thanks for the advice and sry this is my first bike and trying my best to learn about it but need help from experienced Vulcan owners..

You shouldn't have to re-jet if you take the baffles out of the stock pipes as long as you keep the stock air box and ears. If you do an earshave you will need to re-jet.
You will lose some torque and power off of the bottom end with the baffles removed, and it will be a quite a bit louder. A cross over pipe will help with that.
You don't actually need a cross over pipe or have to have one, but like I said you will loose some bottom end power and torque.

Did the PO take off the stock air filter boxes and intake plenum (ear shave). If so that explains the larger jets. How do you know you have too large of jets? What size are you running?

the PO told me he has it at 45/145 like i said in previous post i'm new to bikes and not educated on the specifics yet..i know i might be sounding a little repetitive but i want to make sure i get what i want without spending a whole lot or doing something i really dont have to do..it does not have the original air filter boxes but from what others that have seen my photos say it does not have a earshave. any more advice?
