anyone have try to enlarge and put a go little more higher on the auxiliary port exhaust on a 98 srx 700
Sure, you enlarge them, thats where 80 percent of a port job comes from on a srx/viper. No , I wouldnt suggest you make them the same height as the main exh port. The main has a powervalve which lowers the port for increased torq output and low speed response, having the triple ports same height will only lose more compression and take too much response, torq away from the engine.
