I've heard of people putting the mufflers on the wrong side by accident, their bike ran like crap, a lot of sputtering and backfiring on decel.

 

They are designed to run about 80% of the exhaust flow through the right side muffler by choking off the left side. If you look at the front or inlet of the baffles you will notice that one has a smaller opening, that's the left.

 

How do you like the competition baffles?

 

I can see in some cases things can be improved.

I see where this is going!

So would you buy the FM exhuast and mount them assbackwards thinking it would run better when the instructions clearly state which way to mount them?

 

I just looked at them again and I honestly can't tell which one has the smaller holes. They look the same to me.

I like them better than the regular baffles. They are a bit louder but they do pop a bit on decel. Not enough to bother me though.

 

Well...why not give it a try & let us know the results...

 

I swaped the mufflers to see what would happen, bike ran fine. It does sound different, not quieter but more mellow. I read the information on the site and it did not talk about the baffle placement effecting sound, only performance. The bike still has more power then with the stock pipes, my VE numbers still increased when i loaded a new map, and seems to have better off idle torque, with a bit less hp in the higher rpms. I have to ride it a bit more to determine if the sound was affected to a point where it would be worth giving up a few hp for a sound that better suits me. All I am doing in theory is redirecting the exhaust flow to choose the path of lesser resistance and taking a slightly longer rout to exit (like the stock system) which probably is not much due to the straight through design. I understand R&D but it depends on what you are reasearching and developing. In my case I am chasing the best possible sound for me. No catastrophic engine failure occured and the world did not end cause i put the Jackpots on backwards.

 

I like the sound of mine.Never thought of switching them too see what sound they make.
I guess I missed the "sound/DB" part of your post.Sorry

What kind of sound are you looking for?

 

Exactly, it's just exhaust. It's not rocket science. More engineering gets thrown away in the stock parts than most of the aftermarket suppliers combined, it doesn't hurt to experiment.

Mine ran fine putting a more restrictive baffle on the right side as well, but I didn't like the modification in sound. What became even more dominant was the induction noise since the right side was quieter.

Glad you tried it!

 

I figure Fuel Moto added that piece of paper with specific instructions on which way to install my Jackpot slip-on's for a reason. I'm not messing with it.
