I want to change out to some twin pipes for my Aero 1100. The only brands I've found so far that are model-specific are Vance & Hines straight shots and a brand called MAC that makes some actual straight pipes for the Aero. Not sure I want to run true straight pipes but I like the look. Does anybody have any experience with either of those sets, or do you know of any other twin systems that will work? Will the 1100 ACE pipes fit on the Aero frame? Thanks in advance for any info.
