I just installed a 2 into 1 pipe on my 2010 Street Glide. Great looking and sounding pipe but may be slightly louder than I thought it would be. I got the wrapped perforated baffle. Waiting for the Zippers max flow air intake which should be here tommorow

 

Right on.

 

It's a great exhaust you will love it......

 

Great exhaust. I've got the concentric baffle on my bike and couldn't be happier.

 

is concentric baffle louder or quieter?

 

The concentric is the quietest. They'll all get louder over time, but I wanted something I could spent 12-14 hours in the saddle with and not be deafened.
