#217863 dseward (User) Senior Boarder Posts: 268 Exhaust Tones 2 Years, 9 Months ago   Well, I'm slowly making this R* my own. I've ported the intake. Added a K&N filter. Vented the cylinder to a seperate little filter mounted behind the rear cylinder. And have the PMS dialed in fairly good. With running the HK 3" I added the smart parts Hard kore baffles and have it toned down good. My delema is I would like the tone deeper. I had to drill 3 Ø.250 holes in the new baffles to cut the pressure back. That stopped the occasional popping in the carb. But I would like to build a baffle that's really deep toned instead of the two baffles per pipe I have now. Any ideas what might work. (No I can't afford different pipes yet. Plus I like the look of the HK's. [My sons suggestion] )   Logged     2007 Road Star Silverado.   The administrator has disabled public write access. #217918 RangerDan (User) racin the wind, chasin the sun Expert Boarder Posts: 461 Re:Exhaust Tones 2 Years, 9 Months ago   How much access do you have to machining tools, how experienced are you? (I'm out of my league.. I just have friends ) Anyway, I'd suggest experimenting with different muffling materials... I have a friend with a Harley Softail, V&H Big Shots, and custom baffles made by wrapping metal shavings (those long, spirally ones) around as the muffling material.. I have yet to hear a better sounding bike. So maybe experiment with some different materials that can take the heat. Good luck!

But I'm no muffler expert so I was,t sure where to start. I know Curt started experimenting about a year ago. But I'm not sure what he came up with. I'm a Quality Manager in a Steel Stamping plant. So access to material and others talents are also available.( Tool room made the floor board extenders!) So I was looking for ideas at this point!   Logged     2007 Road Star Silverado.   The administrator has disabled public write access. #371174 dseward (User) Senior Boarder Posts: 268 Re:Exhaust Tones 1 Year ago   Well I initially tried the Smart parts secondary baffles. Liked them but still was not the tone I wanted. This season I took them back out and inserted a 5 inch extension to move the original barrels back to just before the end caps. WOW! Has a cool tone and just a touch louder than with the extra barrels. So if you want a deeper tone in your HK's. Give it a try!   Logged     2007 Road Star Silverado.   The administrator has disabled public write access. #371181 Kai_Sayson (User) The Wind is the Spirit... Platinum Boarder Posts: 3789 Re:Exhaust Tones 1 Year ago   Maybe Curt will jump in, he's designed a couple of baffels..   Logged     My Garage Wind Therapy Riders Patriot Guard Riders May you always be in the Wind and May She Always Smile upon you   The administrator has disabled public write access. #371187 dingodango88 (User) Expert Boarder Posts: 518 Re:Exhaust Tones 1 Year ago   Curt designed a set of baffles (torque chambers) for my VH longshots yesterday. They sound GREAT! Talk to him, he can help you out.   Logged     Sig Pic deleted - larger than 450 pixels and 50 KB   The administrator has disabled public write access. #371191 Curt (Moderator) Never to old to ride! Moderator Posts: 12504 Re:Exhaust Tones 1 Year ago   The HK baffles are self contained.... in other words that are baffles inside an outer pipe inside again inside the heat shields. I found that by adding a 3" piece of car tail pipe the same diameter as the inside of the baffle to the end that is change the tone. It get rid of the tinny sound. I made Ryan some torque chambers yesterday and installed them on his V&H long shots. Just for fun I had a set of slash cut tip for my Bub Stubbies I stuck them up to the end and they made the sound much better. I have several baffles I have made for the HK's I used to have but none can come close to the sound of the Bub Stubbies with torque chambers. Here are some of the baffles I have made. Baffles More of them   Logged     My Site Black Ice is Shiny, Black Ice is Deadly, Ya Wanna Ride My BlackIce?   The administrator has disabled public write access. #371533 dingodango88 (User) Expert Boarder Posts: 518 Re:Exhaust Tones 1 Year ago   You got that right about the Bub stubbies. I cant stop thinking about how your bike sounded...amazing.   Logged     Sig Pic deleted - larger than 450 pixels and 50 KB   The administrator has disabled public write access.
