I totally agree! Is it necessary to include the regulators... Or is it a ploy to hike the price up!
Check out the pic I enclosed... I highlighted the area with a box. I remember reading that it is a muffler section only, but of course, cannot locate the source at this time! But if you look at the pic, it appears that the stock B-Pipe (straight section that connects the cat/header to the rear muffler section) is retained, and that the Dinan muffler is added and clamped/sealed? This was kind of a turnoff for me...
Thoughts?
