I need some help here. i am wanting to do the High flow cat option but i was wondering if anyone knew where you can buy the BOLT ON Product. i would like to extend the pipe diameter from the headers as well as put in High flow cats. I would like the larger 3" diameter all the way back to my Flow master exhaust. Does anyone have any idea where i can get the R and L kit for a 2007 Ford F-150 with a 4.6? Also if you have experience wiht any other way i am more than interested to hear your response. thanks so much
