Muzzy Whisper Cores

Just finished putting Muzzy Pros on my 2010-----they're loud !!!!!! Has anyone tried the Whisper cores and if so are they much quieter and do they have much of a negative impact on performance ? Thanks BLW

They will make it quieter than stock. As long as you havent big bored your engine the negative impact on performance is nominal. You wont even notice in the seat of the pants feel. Now a big bore engine HAS to breath and it will take a good chunck of HP away. NO engine mods I would definately recomend them.

I have the Whisper Cores on my '09, and they are great. The Muzzy Pro's are awesome, but a little loud for blasting through my neighborhood, so I did the Whisper cores, and love them. I can swap them out in less than 5 minutes if I want to get loud again. No change in performance here - stock motor with MSD.

Here's a vid I made....

+1, I agree with everything you said. No power change I can tell, maybe better power with the cores on a stock machine, maybe.

After all of the pipe testing I have done it would lead me to believe that the whisper cores would actually produce more power on a STOCK MACHINE that without them.

That makes sense because some where I remember seeing that on dyno testing showed that on a stock machine that the standard Muzzy actually dynoed like 1 hp more than the pro so that little extra back pressure with the whisper core insert should memick the standard in the pro but I am just a plain ole reneck from hillbilly hollow, we actually rate things around here in mule or jackass power (MJP), If anyone need a conversion chart from MJP to HP give me call.
