So I read on here that the more packing you put in, the louder it is, not really true, my jardine is a hollow pipe pretty much and love the sound of it, did my own exhaust mod and cut all the pipes out of the middle section then filled it with SOS stainless steel pads, I spread them out first then layed them in, somewhat tight, and honestly it sounds stock.... Also did dual outlets that are about 2.5 inches diameter, also feels like I lost some power around 3000 rpm, I will be looking on these threads to figure out what people have had best results with. Anyone have a jardine and do this mod? Love the sound but hate the jardine look

Mine is a stock pipe with middle pipes in tact, cut out the butterfly valve and left an open chamber at the front, cut out pipes at the end and created an open chamber at the end. wrapped fiberglass mat around all 3 pipes in the middle and then hard packed the around the pipes with fiberglass muffler packing. my outlets are 3 inches long by 1.5 inches wide at one end and 1 inch wide at the other. i only have a 2 inch wide perforated section on the 2 larger pipes. the middle pipe i left intact.

From my experience you don't want too many holes in your baffle. 2 inches worth of holes is fine.

Now have full rev range and acceleration, more torque down low and no longer have any flat spots. I have a EBR ECM pre-programed for a Drummer SS.

it sounds awesome.

will post vid of it running next sunny day.
