Hello everybody, I am new to the site and need a little help. I bought an '08 Ultra and the stock exhaust is not too bad for sound but they are ugly. A buddy has a set of Screamin' Eagle slip-ons part no. 80506-07. I ran a search on this site and came up empty. They don't come up on the Harley P&A either. The slip-ons are stamped "system meets EPA requirements of 80 db" etc. when used on FLT1584. Anybody know anything about these, how they sound, any download required if no air filter change is made?

 

Pretty much all screamin eagles w/epa requirements have no bass or real sound. If you change pipes you should add the A/C also it will make the pipes you get sound better. More air in more air out. If all you want to do is those few items look into the FUEL PAK by Vance and Hines. You'll thank yourself later.
