Resonators help for sure driving wise, but the cold starts are still brutal. Actually the more I have had it, I think its a little too brutal on cold start and want to explore some options on taming that if possible.

I want that cold start to be the daily driving rumble

I put the Corsa system on my 6.2 2022 High Country. The cold starts were awesome, but was too loud while driving....especially on the highway at 70-80 mph. I did notice some drone while in stop and go traffic that was quite annoying. Ended up putting on the Corsa resonators and now its great. Not perfect though. Only complaint is that at 75-80mph on the highway, its loud. Cold starts are still good too.

LMAO, man its tough. Mine gives me a glare every time we start up. I did the Corsa resonators but its still a brutal start. IDK if adding a 3rd resonator right after the muffler is worth doing or not. I am considering it but dont know how much itll affect performance.

As soon as you start it up, put it into gear and the rpms will drop so it is a little quieter.
