LB7 Intake horn mod question
Hey guys Im planning on doing the intake horn mod to my truck tomorrow but I have a few questions I need answered before I start this... And I've spent the last hour reading different threads about this and havent found an answer yet..
I understand how and why we do this but Im a little unclear on how im supposed to grind material down to 2.8 inches exactly? Im just afraid of getting a little off track and grinding a hole in it...
