Borla Atak for 2020 AT4

GS357 S · August 14, 2020

Looking for a new exhaust for my 6.2 AT4. Leaning toward the Borla Atak system. Appears to deliver some sound and performance gains. Talked with Borla Engineers and they say absolutely NO drone on the Atak system ay any RPM and no problem with cylinder deactivation. I just don't want it to be too loud at cruising speed but have not heard of any complaints. Ready to pull the trigger on this but looking for any first hand experience with the Atak system. Thanks

I put this system on mine, super easy install!!! At first was taken back by the sound but within around a thousand miles everything settles in. If you get on the gas you are gonna know along with when it cranks but overall I love it!

I ended up going with a custom shop. Did true dual exhaust from headers to tips. X-pipe to deal with V4 sound issues. Probably acts as a resonator.
Sound is very manageable, but growls at throttle and start. I almost want to get a bit more sound out of it, but that’s coming from noisy import life. I do notice a bit of drone at highway speeds though, so I’m going back to try and sort it out.
It just came out much cheaper than a borla, and I expect better performance not having to share the piping.

I have the exhaust on my 6.2 and absolutely love it. The start ups in the morning bring a smile to my face. I had my husband drive next to me with the windows up and cruising and he says he can't hear the rumble. But when I got on it he said it sounded mean and awesome. I have found the sound is different between the sport mode and normal. Sport definitely is throaty but I love the sound of a V8 LOL! Honestly I feel like Borla perfected the system with this ATAK version! Highly recommend. If I could figure how to get you some video clips I'll try uploading them. Pull the trigger, you won't regret it

Thanks for all the replies. The true duals look really clean and well done. I know the Borla is more but some of the cost is the R&D to get that exact right sound balance. I had Corsa on the last truck but not too many thumbs up with Corsa on the 6.2.
