Has anyone here used this product: http://www.apexi-usa.com/produ...Num=1
I was cruising on-line and I found that overpriced product very interesting.
Makes me wonder what scenarios can this open complement. Such as if you are running 3 inch exhaust, but you are N/A, could this be used to create back pressure at low RPM, and gradually opens up as the rpm climbs to allow the exhaust system to utilize it's top end performance of the 3 inch piping?
Just a thought.
