I installed a Vance and Hines CS One on my 2011. it looks and sounds great but now there is a slight engine miss at low RPMs in first and second gear. Other than that she is running perfectly. Any ideas?

Sell it and get an Area P or Muzzy instead.

Just for Pokey's sake, I will point out that it is not an "aftermarket exhaust", it is an "aftermarket muffler" or even "aftermarket silencer"

Well.... guess it depends. Where I grew up, the "exhaust system" (AKA "exhaust") was everything from the exhaust manifold, through the front pipes, cat, mid pipes, muffler, and tailpipe.

Back to the issue at hand. Is this 'miss' occurring during acceleration or deceleration?

There is no way that a slip on exhaust should create any issues with the way the bike runs. I'm guessing it is unrelated, or when you installed it you accidentally knocked a wire connector off something (although I can't imagine what). Good luck and keep us posted.

Pure speculation here, I would guess that the "Miss" was always there, the differance being you can hear it now. Easy check, reinstall the launcher and see if the miss goes away.

Well, if you can't hear the miss with the launcher installed wouldn't it seem to go away if you reinstalled the stock pipe? It'd still be there, it would just be silent again...

You've had this muffler since November, has it been missing the whole time?

If the "miss" is only on deceleration, it is probably a backfire/burble everyone encounters with an after market muffler. Try the "holeshot" fix. http://www.holeshot.com/

That was kinda the whole point of my saying this is not an "aftermarket exhaust", if it were, that might actually account for something.

McJunkie · « **Reply #13 on:** July 12, 2012, 04:27:36 PM »

This could be caused by more air moving through the new can and the bike running leaner because of it.

Not true at all, especially if the fueling is somewhat lean to begin with "which the C14 is not".

Yeah, right! As my friend's daughter says.... " W H A T E V E RRRRRRRRRRRRRRRRRRRRRR"

I have a 2011 with the vance and hines CS1 with no issues. is this your first time putting a pipe on a bike? You mght be hearing the burbling on deceleration is all. Every bike ive owned i put a pipe on it and never had any issues except the burbling and occasional pop on the decel. It isnt a problem and you will learn to enjoy it .

Boys, and you know who I'm talking about...

On a bike with the catalytic converter still in the header pipes (meaning still on the bike) there is just not that much difference in back pressure with a slip on pipe vs stock.
