Muffler change only.

After PM'ing Cc1999 and finding out what Corsa muffler he bought, I took the plunge for my 2020 6.2 AT4. The previous owner deleted the flapper and muffler and left the resonators. I loved the sound on start up and around town. I never really paid much attention to the drone, and there was definitely drone, until I took a 600 mile trip with my son in my old truck last week, it was a game changer.

I ordered the Corsa Sport Pro on Monday, got it Thursday, and had it installed today. Sounds good on startup, quietens out til you get on it, and no drone.

Here is what I bought and where I got it.

Sorry to bring up an old post. But did you need anymore piping in order to make this work? Or was it all just plug and play after cutting the stock muffler off?

To be honest I don’t know. I had a shop do it.
