Had a little lull in the shop, and blew my new Borla touring mufflers on. They sound real good!! I haven't gotten them out on the freeway yet, but I tell you, they sound real good going sideways down the surface street!! I'm glad I bought these, they seem to be ok as far as drone is concerned, as well

 

Running the axleback with stock exhaust?

How much louder would you say they are than stock?

 

Yes just the axle backs. At idle a little louder, with good sound. Hard acceleration, louder by about 15-20%. At cruise,. louder, but inside is very quiet, no droning., very comfortable as far as noise level. But get on it, and these are NICE!! Remember this is from a harley guy, who knows what exhaust is supposed to sound like!!

If you are looking for loud exhaust these aren't it, I'm kinda old, and want my car raspy, but not overwhelming
