Cutting baffles 6 Years, 3 Months ago  
Been kinda bored the past couple of nights, so I decided to pull the baffles on my Freedom duals. I wanted to see for myself how it'd sound! It sounds "wicked nasty!" as in bad a$$ for you older gents! I think I woke up half my neighborhood this morn when I rode to work at 6am & I was barely putting along!
According to the seat dyno, it feels that I lost a little bottom end torque. I was wondering if I cut the baffles in half...so they'd be 8" in length as opposed to 15"...if that would help restore some of that lost bottom end. Would I have to tweak the PMS a bit too? Any input would help! I know Curt & some of you other members have some info on this! I've attached a photo of the baffle as well.
Thanks, Chris

I pulled mine out for a short ride and lost alot of my "get up and go" I think if you cut them back some you may just need a tweak on the screw.

I did just that with my V&H baffles... but, I went a step further to help flow... I welded a small thin walled pipe in the middle to add structure and help with flow. It fit perfectly to the ID of the baffle... a few tach welds and she was done... sounds awesome and I didnt loose any performance...

You can make your own Monster baffles. Go to the auto parts store and buy 4 tail pipe reducers that got from the diameter of your baffle ends (like 1 3/4" down to a smaller diameter (like 1 1/2" and weld the small ends together. Drill a hole in the 1/3 portion of them weld a metal rod with a washer welded on the end and you have your monster baffles for about $12.

Sweet thanks Curt! I also found a site which explains a few things about the angle the washer placement. Very interesting stuff!

Re:Cutting baffles 6 Years, 3 Months ago  
Nice link! and the piece of pipe I welded in is not that long... I think I made it 3" long... still being able to let the baffle do what it is suppose to with the louvers punched in the sides... I like the idea of the tunable baffle too... think I may try that out as well...
