LRD Pro 4 Series Full System

[Jub04Cobra]

I plan on getting an LRD full system exhaust and I was wondering what jetting it will need. I have a K&N and I plan on removing the lid. Its a 2003 ltz 400. Also, what is a good name brand for the jet kit. Thanks

I had a LRD full system on mine with a Dyno-jet jet kit and it pulled pretty hard. the dyno-jet kit has great directions and jetting specs.
