Well that's great to hear! Thanks for the reply; maybe I'll look at doing this sooner than later.

Thanks for the response. I don't know if I'll do headers in the future, so I may just stick with the ATAK system.

Hey all, First post, long time lurker. I drive a 2015 Sierra All Terrain with the 5.3L . I am planning on doing a few mods once my warranty runs out in about a year's time. What i have been considering is the Borla ATAK stainless steel cat-back exhaust system with split side exits with the black tips and getting a cold air intake system as well. I've looked at the K&N 71 series blackhawk induction cold air intake system or the Airaid MXP cold air intake system. Has anyone had any experience with these products? Is it worth my money installing these? Will I get much of a drone when my truck is in V4 mode? I know they won't give me huge power gains, but i'm mostly looking for a good rumbling sound from my truck. Thanks to all in advance! Crunchy
