well a 6 inch lift itself is not gonna be efficient. i suggest looking at cat-back systems, flowmaster or magnaflow. exhaust exit location is personal preference. and there are lots of options. check out http://summitracing.com or http://jegs.com just to name few dealers. good luck

yes you are very right thats why i want to get as much out of the engine as i can with the lift
