Big AP

Didn’t mean to get off on the wrong foot fellas, I’m just frustrated. I’m taking it back and hoping he can make it right. I’ll show you guys the final product. Apart from the headache and disappointment with these headers, the sound is great and the truck is mint.

No ****** Sherlock

I have attached a video of the sound. At 3000RPM there is a god awful grinding sound IMG_1304.MOV

So I drop my truck off last week to have DNA Headers installed (I will never buy again, I’ve learned my lesson) The mechanic cannot get anything to line up, has to dent headers to fit, slip joints leak, Y Pipe does not line up, it’s a nightmare. Guy gets back to me 6 days later with a nearly $1400 Bill. He was supposed to dyno tune the truck but says he just did a street tune. One day later I have check engine light on and get this sound. Very frustrated, I have a near mint 2016 Sierra Z71 with 48k miles that sounds like it’s going to fall apart. The performance upgrade was very underwhelming as well. What would you guys do/think I should do? IMG_1304.MOV
