I ordered two of these baffles for a 2001 Honda Sabre 1100 that I purchased on 070514. The previous owner had removed the baffles. I found the sound to be obnoxious and researched Dennis Kirk for a replacement. It took me a whole 5 minutes to install both baffles. The bike sounds great and my wife will not go deaf riding with me now.
Put these in my slashdowns and what a difference at road speeds, did not change the tone at idle or throttle but at cruising speeds it took the sharpness of the roar down. I can here my cycle radio so much easier now, befor it was turned up full blast and struggled to hear it with half helmet on now I am turning down the volume, the little extra backpressure seems to help the torque curve over the straight thru baffel. If I want loud sharpness it takes all of 5 minutes to switch them out
Installing these baffles gave me the sound and volume I was looking for originally from the Speedster Shorts I installed on my 08 Mean Streak. I do wish they came in pairs, and with instructions. The installation is pretty simple, but not completely intuitive. The increase in back pressure seems to improve the tune and throttle responsiveness. So I can now ride without earplugs while still enjoying a serious rumble!
I have a vulcan 900 after putting on the cobra slashdowns 4818. Speeds above 60 something bothered my ears tone wise. Added these baffles and it is all better. The bike has a deeper tone it. It also felt like it had a little more power. The only reason for 4 star is the lack of information on these in the description. Dennis Kirk did a great job at getting these to me. Order them on Monday had them on Tuesday. 1 day very impressed.
not sure who these would be good for . . . except some compliance reasons . . . . i have Cobra Dragsters on my 1100 Honda Sabre . . . love the blub blub sound at idle and low/medium rpms. . . . . beautiful sounding pipes. . . .when you really step on it . .the pitch can be "sharp" . . from the reviews i found said that it takes it down a couple decibles and takes the sharpness away . . . .that's absolutely not what i experienced. . . . the quiet core baffles completly changed the quality of the Dragsters . . . did not resemble the same pipes with standard baffles. . . . sounded like a slighly louder stock ride . . .none of the balls and rumble. . . .rode down the block and promptly removed them . . .i thought they sounded terrible, absolutely different. suppose if you live in HOA type neighborhood or you are riding long distances at highway speeds you might consider for temporary . . .otherwise . .
