BEST long tube headers for 2012 suburban

[TurboMic]

LOL changed the title for you Mic

Thanks homie

Calspeed 1 7/8 won't fit the 4x4. Kooks might. ARH will. Just expensive.

Your main problem with a NNBS 4x4 and headers is the driveshaft. Something that hugs the block a lot will usually put the collector right where the driveshaft goes.

Cool, not real worried about price as long as it fits. Where do I get AHR? Haven't heard of them
