Normal exhaust flow?
I traded my FLSTC in about 2 weeks ago on a new FLHTCU. The dealer installed Vance and Hines Oval slip-ons the day of purchase. Today I was standing behind the bike while it wasrunning to listen the sound and I put my hand close to the exhaust. I noticed that the right side had a lot more flow coming out of it than the left side did. I know there is a "crossover pipe" butis this normal? I figured that crossover would equal out flow??? I have never owned a bike where the exhuast pipes come out both sides...

With the stock headers the crossover will put more flow and sound both out the right side.

RE: Normal exhaust flow?
This is normal. The factory header is essentialy a 2:1 system. It will deliver more TQ & HP with the Ovals than a true dual system. Stick with it. At idle, if you put a handkerchief close to the left exhaust (looking from the rear), you may see the cloth sucked inward slightly due to negative pressure.
Did the dealer change the air cleaner to a high flow system?
Some dealers are taking shortcuts and doing a HD Digital Tech "race flash" along with a hi flow cleaner. This is not the correct route. You need to install an EFI mapping system..PCIII or SERT for example.
