- Harley Davidson 2009 CVO Roadglide (110)
- Recalibration : SE super tuner
- 4'' Megaphone (slip-on)
- Each 13 discs for right and left

Above is present configuration of my bike. It runs okey and I am quite satisfied with torque and power.

In case of slip-on, we use stock header pipe. Pre-2009 (~2008) Harley touring cross over exhaust has different right and left exhaust ratio. About 60~70% of gas are through right side pipe. Therefore, when slip-on Megaphones are installed, 60~70% number of discs should be installed in right side.

Now I wonder what is the right and left exhaust ratio of 2009 Harlley Touring 2-1-2 header pipe. 50:50 ? or 60:40 (70:30) like pre-2009 cross over type ?

Accroding to correct right and left exhaust ratio, I think I have to change the number of discs in my left and right pipe, presently 13=Right and 13=Left as I thought the exhaust ratio is 50:50...

Please let me have your advice...

We run the same on each side with the new Head Pipe.
It is a true 2 into 1 into 2 pipe.

how many discs is a real close number to run on a 110" with just a set of the mufflers, perhaps a bit more aircleaner, and a good tune????????

thanks happy

start with 10, that is a good flow/sound balance.
Be sure to use liberal amounts of the anti-seize that come with the mufflers.
