I have a 2010 Ultra Classic Limited, and recently changed my exhaust from stock headers and Screaming Eagle Street Cannon Mufflers to Cobra 4.5" Powerflo Mufflers and Fullsac x pipe headers. I also changed from stock air cleaner to screaming eagle and Screaming Eagle Race Tuner.

I love the new set up! Sounds amazing. Deep growl from Cobra exhaust, and definitely great volume, but not so much that they are obnoxious. Sounds awesome when you crank it, but can still hear the radio when cruising. Much louder than the SE Street Cannons. The Cobra Headers also come with a lifetime warranty, so if they change color, or have any problems, they replace for free.

The headers seem great too. Definitely a huge drop in temperature on the leg. Not only do you get rid of the catalytic converter, but they are ceramic coated too. They use the stock heat shields, so if you want a new look, these aren't for you.

Definitely a better throttle response with this total set up.

After all upgrades (Mufflers, headers, AC, and Tuner)
HP 79.61
Torque 95.22

 

Yes sir Cobras are great I've had my cobras since 08
and they still look and sound wonderful.
