I'll post videos when I can figure it out Added a black widow venom 250 yesterday. Very happy with it. I left the resonator and factory GMC tip for now, I like the way it looks and I was nervous about it being too loud Anyways, it is exactly what they advertise. All tone and no drone. It's got some bark on cold start, around town you can hear it leaving a stop light and the idle is nice. Zero drone on the freeway - you really have to get on it to even hear it. I know a lot of you like magnaflow but I like to be different. They seemed too quiet to me. I haven't seen or heard of any tahoe or yukon with a black widow. Feels like it freed up some ponys but what do I know... I have an updated superchips tune running 87 power and 4cyl delete, AEM drop in. Still waiting on my airaid jr - should be here this week but it was promised last week.
