bike was running perfect with rush exhaust .pulled them off and put the Kerker stout 4 inch on and now it is running like really bad ---jumping and lurching on takeoff but runs like a scalded dog after you get it above 40 mph.tried them once before about one month ago same result.my bike is an 08 flhx streetglide fuel injected and i am thinking it has to do with the computer.-thanks in advance for all info

Have you had the air fuel ratio adjusted from stock? What engine modifications have been done?

Do you have the system number for the Kerker Stout mufflers you have purchased? I would need the system number from your purchase receipt.
Not the number on the muffler body.

If you are using the stock fuel map on your 2008 fuel injected FLHX and no other modifications have been done to your motor, then you may need to have your bike looked at by a qualified technician.

Also what is the part number for our slip-ons. I still would like to know which model of our Kerker Stouts we are talking about.

If you feel fuel adjustment is required then there are other options for that as well. FuelMotoUSA.com offers great tech support with the fuel tuners they sell. They also are very familiar with our products.
When tuning with our exhausts it is best to find someone with previous experience tuning our systems otherwise the results may not be the best.

The numbers you gave reference our muffler body which is used on the 2010-12 models as well as the earlier models. I was trying to determine which model you had. The core assemblies are different for the early and late model Stouts. FuelMoto sells DynoJet Power commanders which is an aftermarket fuel management add on. I am not familiar with any tune shops in your area.
If you decide to get your bike dyno tested then finding a shop that has experience dyno testing with our products is recommended.

I am sorry to hear that. Our Stouts were designed and tested to work with the stock air/fuel ratio as well as aftermarket fuel management modules.
