Borla Atak CrateMuffler Anyone?

Philipgonzales3 · September 22, 2020

So I just ordered this muffler yesterday. I called Borla to ask them if I should remove the resonator or leave it and they told me this muffler was designed for crate engines and is not the correct muffler for my truck. Seems some ppl just swap this muffler and it sounds virtually the same to them as the catback system. Anyone on here do this yet? I have a 2020 6.2L RST and since I already ordered this I figured I'm going to just swap the muffler, delete the flaps and send it! What do you think?

First cold start with the new muffler. Full disclosure, the muffler is only halfway welded in, the shop ran out out of gas for the welder! Told me to go back today, oh well, not a big deal to me. I haven't even paid yet lol. Was going to remove the resonators but not 100% sure as I'm loving the way it sounds currently.

Got the resonators removed. Sounds a little deeper/meaner to me. Only got the truck up to 50 on the access road but it's crazy how quiet it gets at that speed. Will have to take it on the highway anothrer day but so far no done! Loving it!

Ok, last video for now. Cold start with resonators deleted a few light revs. Phone audio doesn't do it justice. The revs sounded so loud and mean. Guess it's a little too much for the mic lol.
