Talking wired open my 5th and 6th port actuators, HUGE improvement

Hey all. as can be seen in the title, today I wired open my fifth and sixth port actuators, and MAN what a difference. I can just barily feel any low end loss, but the mid to high end gain is incredible. I only drove it for about 5 minutes after the mod, but it's sweet and i instantly noticed a difference, even coming down my little side road. anyway, i recomend to you guys who have "modified" exhausts that don't use the actuators to wire them open, or get them to open using one of the many other methods. Wiring them open is easy and free, so that's what I did for now. Maybe I'll do something a bit more sophisticated later. Anway, just wanted to let you all know that it's definitely an easy and cool thing to do

People say that there is no actual improvement if your 6-ports were working before. That is because they open automatically anyways. Wiring them open does nothing but take away the low-end.

Nice to hear you like it though.

With the presilencer installed, they open yes but they open at a higher rpm. I found wiring the aux port sleeves essential with a free flowing exhaust to preserve the midrange.
