Why I love FT86 Speedfactory and this header = because they are the ONLY and first manufacturer (including the bigger companies too) to install, dyno and also make a video of their header on a full stock exhaust system while marketing it. That can be funny and/or dumb to some, but to others, including me, that's gold
...just means they actually consider people/tuners of all kinds, including the conservative ones that want an ultra quiet DD and want to keep a stock exhaust. Might seem minor...but if you think about it, who has ever done this??
