American Custom Slip ons
Hi all,
I just installed American Custom Slip ons on my new Deluxe instead of buying a whole new system ( stock sound like a bad lawn mower). The sound is way superior to my stock exhaust but the de cell popping is really crazy. I'm I running too lean, too rich? Do I need to tune?
If I need to tune I might as well put on a new full exhaust and air.
Your feedback would be greatly appreciated .

I have them on my 2k Heritage. Originally went with the completely gutted pipes but was too loud for me. Ordered the mid baffle and it's just right. I get no decel popping at all to speak of. Do you have baffles or just the straight pipes?

My brother and i run them on our bikes and they run great. We have the mid range baffles in them. We both have the cobra fuel controller plus an intake upgrade. We get good power and never get any pop on decel.
You might need to adjust your fuel.

I have Vance and Hines slip ons. I had the same popping when I would decel. I put a high flow air filter and Powercommander V which i had Fuel Moto download a map for my application before they shipped it to me. It works great. No more popping and better throttle response.

Decel popping occurs when one of two things are present.
1. The bike is so lean the exhaust is super heated and is burning the unburnt fuel that is in the pipes (there is always some unburnt fuel in the pipes no matter how lean). This is very rare, and does not occur with the stock map and free flowing pipes being the only change.
2. The AFR IN THE pipes is just right to burn the unburnt fuel. This is quite a common occurrence when free flowing pipes are installed (whether or not a free flow A/C is installed). It can also occur if there is an exhaust leak that is introducing extra air into the exhaust tract.
To get rid of decel popping a lot of people put MORE fuel than is needed into the engine/over-richening the AFR so that more unburnt fuel goes into exhaust, changing the AFR in the exhaust so that is no longer optimum for combustion in the pipes. This is just a waste of gas. And if using decel enleanment found on most tuners it is still really hard to get rid of the popping/burbling when the injectors kick back in at about 1750 rpm.
Another way to get rid of decel popping is to change the AFR in the pipes (mufflers/Slip-ons). This can be done with different baffles, a lolipop or Thunder Torque Inserts. The benefit to the TTI's is that it will let you keep your sound, increase the low and mid range power, and reduce/eliminate the decel pop by reducing/eliminating reversion, thus changing the AFR (in the pipes) to one that is not conducive to combustion.
Hope this helps you out
