2013 GMC Sierra - Mini Outlaw 127H Train Horn Kit

Jonathan T. just leveled up his 2013 GMC Sierra with our Mini Outlaw 127H Train Horn Kit and it’s sounding absolutely nasty in the best way! :loud_sound::fire:

This clean GMC just got a whole lot louder thanks to the insane power packed into the Mini Outlaw setup :muscle:—perfect for turning heads, clearing traffic, and making some serious noise at shows! :sunglasses::articulated_lorry::dash:

:white_check_mark: Compact & LOUD
:white_check_mark: Easy install
:white_check_mark: LEGENDARY HornBlasters sound :triumph::loud_sound:

Huge shoutout to Jonathan for killing the silence the right way! Can’t wait to hear this beast blastin’ down the street! :truck::dash::boom:
