Did the "lolli pop" mod today
Well it was raining today so instead of riding my bike I decided to mess with it. I left the baffles in and put the 1/4 eye bolt in the pipe. Im running freedom performance exhaust they are id say 2 inch that go to 2 1/4 at the end of the pipe. I had to hack up the heat shield on the back side a little to clear the bolt threads coming out. I also double nutted it, I'm a firm believer in the double nut/jam nut after racing dirt track for 5 years. You learn to keep things from coming loose. Ill post some pics tomorrow have to recoat my pipes they got dings while I was doing the mod. Anyone else running the lolli pop mod?

Yeah normally I figured id try it with them in still then try it with the out. Here is a link to what inspired me to do it.

You know, you really want to see this on a dyno. Could be its doing nothing or making things worse.
The lollipop is a nice fix for exhausts that have a big reversion issue, usually those with open pipes like drag pipes. On other pipes it seems to do nothing but slow the exhaust gases.
I saw it in action a couple of years ago on a dyno in South Wales. A guy had a Sportster with some gutted Short Shots on it that was running like a pig at low RPMs. On the dyno the AFR and power was all over the place up to 3000 rpm. Then the tuner just stuck the blades of a couple of screwdrivers over the mouth of the exhaust and as if by magic the bike ran better. They made lollipops up with a washer welded to a bolt and when fitted the bike ran much better.

I rode the bike today for about 15 mins and tossed them out. They give the exhaust a weird tinny whistling noise. Maybe it was because I had the baffles in still, oh well at least I wont have to worry bout my baffles falling out now with the new bolts having lock tight and being double nutted.
