I think Fullsac will recore your stock ones .I've read a couple of posts of people who used them and liked them.
Don't know the whole name but maybe if you do a search you'll find em.
I just bought a set of the SE Torque slip-ons, hoping they will do what you describe, but I won't be able to put 'em on 'til I get my SE air cleaner and flash for ecm. I did hear some V&H pipes today that really sounded sweet. Did not seem as loud as the SE II. Not sure which model they were, but were quite long.
The HD Touring Muffler (50 state legal) is alittle louder than stock but not as loud as the SEII. I prefer Rineharts myself. Not really loud unless you want them to be.
