Had the AC slip-ons and catless header installed at Americade 2 years ago...got 2 sets of baffles and the black end caps. Drilled out the second baffle with six rows of 11/16 holes to give me three options...stock baffle quiet but louder than stock...drilled baffle plenty loud enough when you come on to her but quiet at idle...and no baffles loudest but not obnoxious...good deep rumble.
I have put about (25,000 kms)16,000 miles on the bike with this exhaust with no issues...for the money it is a tough system to beat and maintains the stock appearance with the EPA stamp on the mufflers
