I have had my headers on for 2 years now and have not finished the job. I have a crossover pipe (balancing) immediately behind the collectors and that's where I stopped. I purchased some mandrel 90's and 45's along with 2.5" Walker straight through truck mufflers and some 2.5" exhaust pipe. I would like to go with one big exit pipe in front of the drivers side tire, but not sure if 2 into 1 will hurt the performance in anyway. I'd like to see the finished Banks system but, haven't been able to see it online.
