GM Performance Exhaust- Borla ATAK Conversion

[AT4Play]

Hey guys, thought I'd share some part numbers for those with the GM Performance exhaust so you can swap over to the ATAK system. 

 

The parts fit my 2019 Sierra 1500 AT4 with crew cab, short bed, and GM Performance exhaust.

 

Install is simple all i had to do was cut a few inches off the front pipe and it bolted right up.

 

ATAK Muffler - 401318

ATAK Harmonizer - 57022

Clamp - 90122

 

Price was $461 with shipping.

 

Sound differences - Cold start is LOUD for a few seconds and then tames down to a nice rumble at idle (no complaints from the neighbors yet). Good growl part throttle and roars when you step on it. No drone at all, my wife even likes it and we spend alot of time in the truck off road.
