Does anyone have the FLP FL98 headers?
im not sure the FLP has rear o2 provisons in there Y pipe like the jet hots do but if it does then you can run all 4 sensors and be fine. if it doesnt have the rear sensors you'll need to run o2 sims or edit the code out to get rid of the SES.
as far as warrenty contact your specific dealer, they will no more about it then we will, some dealerships void for a k&n, some allow a host of bolts ons, its a toss up.

Give me a call...
